Southern arrow-wood (V. dentatum) is similar, except that it blooms later and has broader, more coarsely toothed leaves and longer petioles. Other similar species are smooth arrowwood (V. recognitum) and Carolina arrowwood (V. carolinianum).

They have very short petioles and velvety undersides. The highly fragrant, nectariferous flowers vary from white (rarely) through pinkish and purplish and occur in umbellate cymes.Liede, S., and F. Weberling. 1995. Plant Systematics and Evolution.

The structure of the petiole is an easy way to visually classify ants, because the major subfamilies of Formicidae have structural differences: some ants have two- segmented petioles, while others have a single-segmented petiole.

Fully grown, the plant is tall with its petioles being circa . Its flowers are white and they bloom from March to June. Its small berry-shaped pome fruits are red. Its branches have long spines.

Since long petioles are the dominant character state in all closer relatives, Coccinia sessilifolia var. variifolia can either be interpreted as a relict of long-petiolate ancestors or a secondary development of an ancestral character.

In young plants the trunks, petioles and rachises are covered in spines. Mature plants typically lose rachis and petiole spines but will retain trunks spines in its new growth. The suckering stems are small to mostly moderate and are among the few in the palm family that branch; among rattans it is the only one with splitting stems. The trunks are bare at the bottom but retain persistent leaf bases in its youngest parts; enlarged paper- like appendages, ocreas, form where the petioles meet the stem.

Drosera dilatato-petiolaris is a carnivorous plant in the genus Drosera and is endemic to Australia, being found in both Western Australia and the Northern Territory. Its leaves are arranged in a rosette and commonly produces plantlets, eventually forming large clumps that can be over across. Green petioles emerging from the center of the rosette are typically 3–5 mm wide, but can vary. Red carnivorous leaves at the end of the petioles are small and round, with most resting on the soil surface.

Typical prostrate shrub habit Banksia petiolaris was first described by Victorian state botanist Ferdinand von Mueller in 1864, its specific name Latin for "with petioles", referring to the species' long petioles. The type specimen was most likely collected in 1861 by G. Maxwell between Cape Le Grand and Cape Arid and is housed in Melbourne. George Bentham published a thorough revision of Banksia in his landmark publication Flora Australiensis in 1870. In his arrangement, Bentham defined four sections based on leaf, style and pollen-presenter characteristics.

Hentak is a thick fermented paste in Manipuri cuisine made with sun-dried fish powder and the petioles of aroid plants. The small Indian flying barb fish are sun dried on bamboo trays and crushed to powder. The aroid petioles are cut into pieces and left in the sun for one day, then in equal parts with the fish powder the mixture is sealed in an earthen pot and fermented for around one week. Hentak is a standard ingredient in Manipuri households, where it is consumed as a condiment with boiled rice or curry.

Stipules can be considered free lateral, adnate, interpetiolar, intrapetiolar, ochreate, foliaceous, bud scales, tendrillar or spiny. A stipule can be fused to the stem, or to the other stipule from the same node. A stipule is "adnate" if it's fused together on part of the petiole length, but the anterior is still free. A stipule is "interpetiolar" if it is located in between the petioles, as opposed to being attached to the petioles, and generally one stipule from each leaf is fused together, so it appears that there's just one stipule between each leaf.

The sexual, reproductive stage, (teleomorph) grows during summer on ash petioles in the previous year's fallen leaves. The ascospores are produced in asci and are transmitted by wind; this might explain the rapid spread of the fungus. The origins of the disease are uncertain, but researchers are investigating the theory that the fungus originated in Asia, where ash trees are immune to the disease. Genetic analysis of the fungus Lambertella albida which grows harmlessly on petioles of the Manchurian ash (Fraxinus mandschurica) in Japan, has shown that it is likely to be the same species as Hymenoscyphus fraxineus.

The leaves of a lateral shoot are further twisted at their petioles to form two pectinate rows in a horizontal plane around the shoot. The leaf petioles in Retrophyllum are uniquely twisted on the lateral shoots in opposite directions on each side of a shoot orienting the leaf blades with the adaxial or ventral surface upwards on one side of the shoot and the abaxial or dorsal surface upwards on the opposite side of the shoot. The leaf blade varies in shape from lanceolate to narrowly ovate. The leaves have conspicuous midribs and are amphistomatic with stomata present on both sides.

The large cordate or sagittate leaves grow to a length of 20 to 90 cm on long petioles. Their araceous flowers grow at the end of a short stalk, but are not conspicuous; often hidden behind the leaf petioles. The corms of some species can be processed to make them edible, but the raw plants contain raphid or raphide crystals of calcium oxalate along with other irritants (possibly including proteases) that can numb and swell the tongue and pharynx; they cause difficulty in breathing, and sharp pain in the throat. The lower parts of the plant contain the highest concentrations of the poison.

The species has often been confused with Vatica odorata, being distinguished by leaves narrowing gradually to a blunt point (instead of being acuminate), the relatively longer petioles, and the less raised main venation. The young twigs and petioles are furthermore covered in pale-greyish scruff as opposed to reddish-brown scruff. According to King in his original 1893 description of this taxon, it is most similar to V. curtisii (now synonymised with V. odorata), especially in its fruit, but he distinguishes the taxa on the basis of this taxon having leaves with fewer and less prominent nerves.

The leaves have blades that are lanceolate to broadly ovate or elliptic in shape without lobes. The leaf bases are attenuate to cordate in shape and the margins of the leaves are usually entire or serrate, or sometimes lacerate. The upper surfaces of the leaves are glabrous or have hirsute to strigose hairs. The basal leaves are petiolate, with petioles that are 5 to 30 cm long and 1 to 8 cm wide, the cauline or stem leaves have petioles that are 2 to 25 cm long and 0.5 to 7 cm wide, the bases are attenuate to cordate or auriculate in shape.

The leaves have variously shaped blades borne on long petioles. The blades are 5 to 15 centimeters wide and may be hairless, hairy, or waxy in texture. The leaf blades are often divided into narrow lobes or dissected into small segments. The shape of the leaf blade differentiates the two subspecies; ssp.

It is a woody perennial bush-like tree 1-5 meters in height. Its stems are erect and covered in small hairs called trichomes. Its oblong, leathery, blueish-green leaves lack distinct petioles and are blunt or notched at their tips. The leaves are 3-15 long by 2-7 centimeters wide.

The leaves have oval blades up to 4 centimeters wide which are borne on petioles up to 7 centimeters in length. Flowers have 5 to 7 shiny yellow petals each a few millimeters long and many stamens and pistils. The fruit is an achene borne in a spherical cluster of up to 15.

The petioles and rachis often have spines, though there may be very few to none. Leaflets are simple, entire, and articulate at the base, with parallel side veins and no distinct central vein. Male cones are cylindrical, upright, hairy, and stalked. Female cones are stalked or sessile, erect, and have short hairs.

The plant is an extremely slow grower. It has abnormally thick traps and petioles, which are probably the reason why 'Wacky Traps' has trouble closing its traps quickly. It takes several minutes trap closure even with repeated teasing of the trigger hairs. Robert Ziemer has tried unsuccessfully to sexually propagate Dionaea 'Wacky Traps'.

The leaves are oval in shape, up to 2.5 centimeters long, and lack petioles. The sepals of the flower separate into two pairs, revealing the lavender-pink blooming petals. Each petal is just over a centimeter long, fan-shaped to oval, and sometimes with a yellow base marked with a red spot.

This plant is rooted from a branched rhizomes which gives rise to long petioles which terminate in smooth floating leaves. Since the leaves are subject to tearing by water and waves, they are round with a waxy upper coating that is water-repellent.Sculthorpe, C. D. (1967). The Biology of Aquatic Vascular Plants.

Petioles are long and spiny. Rachises are with 27 to 36 pairs of leaflets, the ends of which are deeply notched to form a pair of "horns". Inflorescences consist of a peduncle and a rachis long. The rachis bears 2 to 3 rachillae, which are the smaller branches which themselves bear the flowers.

Milicia regia has a wide, rounded dark green crown. The trunk is tall and straight, with smooth, reddish-brown bark. The leaves are borne on short petioles and are ovate, dark green and up to long. They are arranged alternately along the twig and have seven to eleven lateral nerves and untoothed margins.

Biota of North America Program 2013 county distribution map These plants are perennial herbs with stolons. The stems are prostrate or upright and bear leaf blades on long petioles. The inflorescences arising from the leaf axils have two to many flowers. The tubular corolla has two lobed lips, and is generally blue-violet.

Its leaves have thin secondary veins that arch and connect with one another near the leaf margins. Its hairless, wrinkled petioles are 6 millimeters long. Its solitary (rarely in pairs) are axillary and have a distinctive pink to dark-red color. The flowers are born on pedicels that are 3-5 millimeters long.

Daphne species are shrubs, with upright or prostrate stems. Upright species may grow to . Their leaves are undivided, mostly arranged alternately (although opposite in D. genkwa), and have short petioles (stalks). The leaves tend to be clustered towards the end of the stems and are of different shapes, although always longer than wide.

Sidalcea stipularis is a rhizomatous perennial herb, producing a bristle-haired stem up to 65 centimeters tall. The leaves have oval, unlobed blades on petioles and are evenly spaced along the stem. Each is accompanied by short stipules. The inflorescence is a headlike cluster of flowers with a cuplike skirt of hairy bracts.

The actual traps are held by petioles which hold air sacs that aid in flotation. One end of the stem continually grows while the other end dies off. Growth is quite rapid ( per day in Japanese populations), so that in optimal conditions a new whorl is produced once or more each day.

It is a fungal ascomycete that commonly infects seeds, pods, stems, and petioles. This pathogen is also found in its imperfect state, Phomopsis sojae. This is a common disease of most soybean growing regions in the United States. Losses result from losses in field stands, reductions in yield, and poor seed quality.

It is a hairy, erect to almost recumbent, annual herb, high from a taproot. The leaves are oppositely arranged in pairs about the stem. The lower leaves have short petioles; the upper are sessile. Each leaf, in length, is ovate, or triangular with a truncated or slightly cordate base, with coarse teeth.

The larvae feed on the fruit of Hibiscus arnottianus and the petiole of Abutilon sandwicense. The petioles in which larvae are boring become considerably swollen. Full-grown larvae are about 12 mm long and dirty whitish or yellowish with a rosy tinge. The pupa is about 7 mm long and yellowish brown.

A. vicina are known to create outstandingly large nests. The combs themselves are generally horizontal and fairly even, neither convex nor concave. The cells face downward and comb layers are vertically connected by petioles. The bottom combs resemble stratified layers while the top combs expand concentrically to form a singular huge comb.

The leaves have whitish midribs, and are positioned basally and mostly alternately on the stem. They vary from linear and sessile nearer the top of the plant, to oblanceolate with petioles nearer the bottom. The stem is up to . The stem and leaves are sparsely to densely covered with short white hairs.

A large-seeded woody species, e.g. the chestnut, retains the cotyledons inside the seed coat below ground while the radicle grows downward and the shoot appears aboveground. To make a nurse seed graft, a germinating seed is needed. A knife is used to cut an opening between the petioles of the cotyledons.

Rubus is contained within the family Rosaceae (the "rose family"). Rubus means "bramble" or "bramble-like" in ancient Latin, and in Botanical Latin, tricolor means "three-coloured". Focke conferred that epithet based on the three colours of the plant: leaves green above, white below, and the red bristles of the stems and petioles.

It is a bush reaching 0.5-1.5 meters in height. The younger branches are covered in yellow-brown, dense, woolly hairs. Its internodes are 1-4 centimeters long. Its petioles are 3-4 millimeters long and covered in dense woolly hairs. Its oblong to oval leaves are 7-19 by 3.5-9 centimeters.

Boiled corm of Taro is commonly served with salt, spices, and chilies. Taro is a popular dish in the hilly region. Chopped leaves and petioles are mixed with Urad bean flour to make dried balls called maseura (मस्यौरा). Large taro leaves are used as an alternative to an umbrella when unexpected rain occurs.

This cycad contains reddish seed cones with a distinct acuminate tip. The leaves are long, with 5-30 pairs of leaflets (pinnae). Each leaflet is linear to lanceolate or oblong-obovate, 8–25 cm long and 0.5–2 cm broad, with distinct teeth at the tip. They are often revolute, with prickly petioles.

The leaves, which are mostly arranged around the base of the stem, have crinkly or wavy-edged round blades on petioles a few centimeters long.

They may be green or striped, marbled or bordered with pale green, red or gray, and the petioles of some kinds are red. The tiny flowers are unnoticeable and they grow in the form of cordlike spikes. The fruit is a berry that eventually dries out and shows the pepper-like seed.

Polypodium virginianum is a small rhizomatous fern with narrow leaves long and wide borne on smooth, scaleless petioles . Leaves are evergreen, oblong and pinnatifid with acuminate tips. Large, circular sori are prominently featured on the underside of fertile fronds in late summer and autumn. Sporangia are intermixed with long brown glandular hairs.

It is easily told apart from other miniature species of Butia by its densely furry spathes, with the hairs being woolly and persistent (not easily rubbed off). With its petioles lacking teeth along the margin it is most similar to B. archeri according to Glassman in 1979, although a number of other dwarf species lacking teeth have been discovered since then. It grows in the same region as the extremely rare B. pubispatha, another dwarf, grass-like species described as a new species in 2010, which also has petioles lacking teeth and furry spathes, but this species has a spathe with shorter, more pubescent hairs which can be rubbed off, and is also somewhat robuster and larger in size. B. pubispatha also grows much faster.

The flowers have five sepals, two of which are greenish and three of which are cream in color. There are sometimes white petals as well, but these are often absent.

The mine consists of a very long corridor, often following the midrib or the leaf margin, widening in the end into an irregular elongate blotch. The larva may move to another or even a third leaf (all the while mining) by way of the petioles and stem. Pupation takes place outside of the mine.

Young twigs and both sides of the leaves are covered with a white or tawny loose felt. The leaves are ovate-lanceolate, 5-12 cm long by 2.0-4.5 cm wide, with petioles 0,6-2,5 cm. The shrub flowers from February to August.Flora of China; Bean says June or later; Krüssmann 1984, vol I, p.

Pollen Library/ The leaves on the shrub are arranged in an alternate pattern with petioles 8 mm in length and covered in a white waxy coating known as glaucose.Encyclopedia of Life In addition, leaves are thin and smooth and ovate in structure. A seemingly random venation pattern is visible on the underside of the leaves.

Its petioles are 3-7.5 millimeters long. Its flowers are arranged in groups of 3 or fewer on a rachis opposite the leaves. Each flower is on a fleshy, slightly hairy pedicel 10.5-17.5 millimeters long. Its flowers have 3, green or brown, oval-shaped sepals that are 2-3 by 2-3 millimeters.

The compound, alternate leaves are green, also glaucous (excluding petioles), and up to , becoming smaller as they ascend the stems. Lower leaves are bipinnate, while the upper leaves are often simple-pinnate.

Table beet stem infected with Pectobacterium carotovorum subsp. betavasculorum. Note entry through a wound. Symptoms can be found on both beet roots and foliage, although foliar symptoms are not always present. If present, foliar symptoms include dark streaking along petioles and viscous froth deposits on the crown which are a by-product of bacterial metabolism.

Some preparations may include other plant ingredients like Colocasia esculenta. The standard ingredient of aroid petioles enhances flavor and also serves the purpose of aiding the fermentation process. In Manipur, hentak is a homemade preparation that is not produced for commercial markets. It is custom to serve this to expecting mothers and patients in convalescent.

Common differences include leaf size and shape and placement of pubescence on leaf undersides and petioles. Leaves in autumn Larvae of moths feed on V. dentatum.

It has numerous thorns, long. The petioles are narrowly but distinctly winged, and are long.

The fungus grows in the petioles and/or midribs of the perennial plant meadowsweet (Filipendula ulmaria), a member of the rose family, causing swelling and distortion. Sori develop with bright orange spores. The rust's spores reach the new meadowsweet plants via air movements. The rust has a severe effect on the survival of meadowsweet seedlings.

Mature trees branch only from the top third of the trunk. The juvenile leaves have a broad oval shape. The broad lanceolate shaped adult leaves are dark glossy green on top and lighter underneath, and grow to a length of and broad. The leaves have a disjunct arrangement and are narrowly flattened or channelled petioles.

It is common for the petioles of the leaves to have purple, sunken lesions that resemble streaks. If these streaks are severe enough, they may lead to the bowing of the petiole which in turn kills the leaf. Strawberry leaf scorch infects all parts of the flower, leading to unattractive blemishes on the fruit (strawberries).

Unlike its congeners, G. tinctoria and G. manicata, the leaves are small, approximately 6 cm across. They are rounded or kidney-shaped, stipulate on long (2–10 cm) petioles, with crenate edges.

Like other wattles, its leaf-like structures are actually enlarged and flattened petioles known as phyllodes. These are irregularly oval in shape, long and wide and prominently veined.

Evidence of their presence are dead or dying speargrass plants or deep oval notches on leaf petioles. The weevil spends a year as a larva before constructing a chamber in which it pupates for two weeks. After emerging, the teneral adult weevils can stay in the chamber for eight months before emerging, and live for over two years.

It bears small flowers with hairy, pointed sepals surrounding five purple-streaked lavender petals. The filaree fruit is quite long, its style reaching up to 12 centimeters in length.

As N. peltata can propagate through fragmentation, mechanical control is a challenging strategy because it can often aid in dispersal. One approach is to cut leaf petioles one to two times each spring and summer. Cutting, harvesting, and covering plants with barrier materials can sometimes result in a successful control effort. Hand raking can be a viable strategy in very localized areas.

The stems are scantily branched, square and usually hairless, although new growth sometimes has a few hairs along the angles. The leaves are opposite, about long and wide, ovate or broadly lanceolate, with toothed margins. The lower leaves have short petioles and the upper leaves are appressed against the stem.

Each basal leaf is palmately cleft into 3-5 lobes; these lobes are often divided again into smaller lobes. The alternate leaves are similar to the basal leaves, except they become smaller as they ascend the stems and their petioles are shorter. The upper leaves are more slender and divided into fewer lobes. The margins of the leaves are crenate or dentate.

Nymphaea thermarum forms rosettes wide, with bright green lily pads growing on short petioles. The very small flowers are white with yellow stamens, with the flowers held upright a few cm above the plant. They can self-pollinate, and after blooming the flower stalk bends so the fruit contacts the mud. The sepals are slightly hairy, and as large as the flower's petals.

It remains smooth but becomes a pale grey, grey-brown, white or pinkish to coppery colour with ribbons on the upper branches. The thick, concolorous, glossy, green adult leaves have an alternate arrangement. The leaf blade has a lanceolate to broadly lanceolate to ovate-elliptic shape and is in length and with the base tapering evenly to petiole. Petioles are in length.

Different interpretations are also sometimes made regarding placement of various eastern Asian populations of this group, by some considered to represent additional varieties or subspecies, if not different species altogether. The most distinctive physical difference among these plants is usual presence of gland-tipped hairs on first-year canes, petioles, pedicels, and calyces of R. strigosus, lacking in R. idaeus.

Lyonothamnus is endemic to the Channel Islands of California, where it grows in the chaparral and oak woodlands of the rocky coastal canyons. This is a tree growing up to tall with peeling reddish gray or brown bark. The evergreen leaves are shiny, dark green with lighter undersides, and borne on short petioles. The two subspecies have different leaf shapes.

This perennial herb or subshrub grows 20 to 40 centimeters tall. The narrow- lobed leaf blades are borne on petioles up to 3 centimeters long. The flower heads contain several yellow ray florets each about half a centimeter long and many yellow disc florets in the middle. The plant grows in dry, rocky canyon habitat, anchoring in rock cracks and crevices.

Paired stipules are generally present, and are a primitive feature within the family, independently lost in many groups of Amygdaloideae (previously called Spiraeoideae). The stipules are sometimes adnate (attached surface to surface) to the petiole. Glands or extrafloral nectaries may be present on leaf margins or petioles. Spines may be present on the midrib of leaflets and the rachis of compound leaves.

When they occur, the hairs often branch into a star-like shape. The stem scales are iridescent, a distinctive feature of the species. The pinnae, which are alternate on the rachis, range in shape from oblong-falcate (somewhat sickle-shaped) to long-triangular. They are asymmetrical at the base, being attached directly (without petioles) to the rachis near one corner of the pinna.

In the case of L. dorsata, defense is passive rather than active. Nest petioles are covered in a sticky substance that protects the nest and the larva inside from ants. This protection is perhaps the reason that this species has extremely docile females. In many species that employ this method, the small size of the wasps requires alternate defense systems rather than aggression.

A large buttressed trunk of Ficus obliqua, Allyn River, Barrington Tops, Australia. Ficus obliqua is a tree, which may reach in height with a similar crown width. It has smooth thin grey bark with lighter-coloured lenticels, and a buttressed trunk, which may reach in diameter.

Petioles up to 40 cm long bear deeply bifid leaves up to 50 cm long. This plant has a wide but scattered distribution from Costa Rica to northwestern Colombia.

The bark sheds from the tree in short ribbons or as small polygonal flakes. The concolorous, glossy green adult leaves have an opposite to sub-opposite arrangement. The leaves are supported on petioles which are long. The leaf blade has a narrowly lanceolate to lanceolate shape and is in length and are wide with a base that tapers to the petiole.

Colouration is highly variable. The laminae and petioles are often green throughout when produced in shaded conditions and red to purple in plants exposed to direct sunlight. In certain specimens the underside of the lamina and/or the stem may be red to purple, but this is uncommon. A red tinge to the stem is already apparent in many juvenile plants.

This perennial herb produces long, slender stems up to 2 meters (80 inches) long, sometimes growing erect. The leaves are each made up of several narrow leaflets, and some of the leaflets are divided further into lobes. Leaves near the base of the plant are borne on petioles. The inflorescence is a raceme or a panicle containing a few flowers each.

Colona evecta was described from southern Vietnam, it is also found in neighbouring provinces of Cambodia, where the species often survives forest clearing. The tree grows from 6-20m, with radiating pubescent branches and terminal flowers. The bark of young trees is very tough. The leaves are relatively thick, lanceolate, denticulate, glossy on upper sides, with 5–7 mm petioles.

It is a loosely tufted plant growing from a stout stem base, reaching to 10–25 cm tall. The basal leaves are 3- (rarely 5-) foliate, hairy above, and densely tomentose beneath, the petioles and stems with long, straight hairs. The inflorescence is branched, bearing several fairly large flowers. The flowers have five petals, pale yellow, inversely heart-shaped, longer than sepals.

The leaves narrow at their base to form long wings that run down the petioles. The leaves have 16-18 secondary veins emanating from both sides of their midribs. The secondary veins emerge at near 90° angles from the midribs, but curve to join one another 3-5 millimeters from the leaf margin. Its inflorescences have 2-3 green to yellow flowers.

A very variable species especially in shape and size of leaves, and length of petioles and stipules. It is a perennial, evergreen or caducous sub-shrub. Stem succulent, may be branched or not. Stem a thick, dark green- to mahogany-colored conical trunk, up to 15 centimeters in diameter and 30-40 centimeters in height, older parts often with peeling bark.

It is blue-green in color, succulent, and lightly hairy. The oval, smooth-edged leaves are one or two centimeters long and borne on short petioles.

Most of the leaves are low on the plant, the toothed oval blades borne on long petioles. The hairy, glandular inflorescence is a one-sided curving or coiling cyme of bell- shaped flowers.

In gynes the petioles are enlarged, while in males, the outline is triangular. In the forewings there are 4 well formed cells enclosed by the veins, 1+2r, 3r, rm and mcu. The 3r cell has an elongated outline that extends to the upper wing margin. Of the wing veins, the 1RS runs perpendicular or slightly angled to the R vein.

The upper surface of the leaves are somewhat shiny and hairless or sparsely hairy, while the underside is hairless and pale. Its leaves have 10-18 pairs of secondary veins emanating from their midribs. Its slightly hairy to hairy petioles are 5-14 by 1.5-3.3 millimeters.

The lamina is lanceolate, with spined dentate margins and an apical spine. The sarcotesta is orange-brown, the sclerotesta short ovoid to globular, with a network of shallow grooves.

Its leaves are triangular-lanceolate, truncate to cordate at the base, with an acute to acuminate tip. Its petioles are around 3-15 mm. It produces small yellow flowers from late spring through summer. Tragia urticifolia can be distinguished from the similar looking Tragia betonicifolia by its longer pedicels on staminate flowers (1.5-2 mm), which are more evenly distributed in the raceme.

The inflorescence consists of nodding spikelike racemes with numerous drooping flowers. The flowers are bright blue-violet (rarely white), 2 to 4 cm long, with short petioles standing to one side in the axils of the bracts. The bracts are quite different and smaller than the leaves.

Fl. June; fr. November. \---- A small bush, averaging six feet in height, rounded in form, of a bright cheerful green hue, and which, when loaded with its inflorescence of surpassing delicacy and grace, claims precedence over its more gaudy congeners, and has always been regarded by me as the most charming of the Sikkim Rhododendrons. The plant exhales a grateful honeyed flavour from its lovely bells and a resinous sweet odour from the stipitate glands of the petioles, pedicels, calyx, and capsules. Leaves on slender petioles, three-quarters of an inch long, coriaceous but not thick in texture, two to three and a half inches long, one and three-quarters to two inches broad, cordate at the base, rounded and mucronate at the apex, in all characters, except the evanescent glandular pubescence and spherical buds, undistinguishable from Rhododendron Thomsoni.

They are dark green above and pale below and are generally 5 inches long by 1.5 inches wide. The leaves are petiolate with petioles of 0.5 inch length. The Inflorescence consists of a long axillary peduncle which bears short clusters of sweet white-smelling flowers, each cluster supported by a leaf-like bract. The individual flowers are sessile and may be with or without bracteoles.

H. benghalensis is a stout, high-climbing liana or large shrub, with white or yellowish hairs on the stem. Its leaves are lanceolate to ovate-lanceolate and approximately long, and broad; petioles are up to 1 cm long. It has scandent branches up to high. H. benghalensis flowers intermittently during the year, and produces fragrant flowers borne in compact ten-to-thirty-flowered axillary racemes.

The flowers are white fading to pink; blooming from June to August.

Rosa stellata is a species of rose known by the common names desert rose, gooseberry rose, and star rose. In Texas this type of rose grows on dry rocky places to , such as the Trans-Pecos. It occurs in the mountain canyons of Arizona and New Mexico. It has trifoliate leaves, deep rose purple blossoms and yellowish white prickles on the petioles and stems.

Pseudotrillium rivale is a rhizomatous herbaceous perennial growing up to in height. The three bracts have generally lance-shaped blades up to long borne on petioles in length. The blades are glossy blue-green with silvery venations. Atop the whorl of bracts, on a pedicel high, is a single nodding non-fragrant flower with green sepals and pink-blushed white petals up to long by wide.

Like seedlings, adult plant shade avoidance involves several mechanisms acting together. Petiole elongation is both a result of cell expansion and cell division, though not at the same stage in petiole and leaf formation. In newly growing leaves, cell division is the primary factor, while fully formed leaves and petioles rely on cell expansion. Xyloglucan endotransglucosylase/hydrolases (XTHs) are a family of cell wall modifying proteins.

Ginkgophyte foliage has stayed largely consistent since the Mesozoic. Its historically wide territory makes it an important leaf morphology, and its unique stomata and isotopic profile give it a key role in recreations of the Mesozoic and Cenozoic. Leaf fossils that resemble the Ginkgophytes are known as Ginkgoites. There are similar, now extinct, morphogens, such as Sphenobaiera, which describes fan-shaped, deeply divided leaves without clear petioles.

The leathery leaves are fascicled and about 25 mm in length with very short petioles. Like most Grewias its leaves are markedly 3-veined from the base; leaf margins are bluntly toothed or crenate to almost entire. Flowers are small, bright pink and fragrant. The hairy fruits are fleshy drupes some 20 mm across, reddish brown when ripe and either entire or deeply 2- to 4-lobed.

It grows slowly, and can reach 1000 years old. It has broken bark with ashen gray color. Older branches have the same design, fractured and ash color, which gives the tree a grizzled look. The leaves are oval, almost sessile, shining above, and dark green, with seven to 9 leaflets, imparipinnate with petioles a little winged, flowers in racemes lax, the male and female on different trees.

Mature tree showing trunk and foliage kernels. Karaka is a leafy canopy tree with erect or spreading branches. It grows to heights up to 15 m and has a stout trunk up to 1 m in diameter.

Lamina are elliptic-lanceolate to elliptic-oblanceolate, narrow-oblanceolate, or more rarely linear- lanceolate. Petioles are 1.5–9 cm in length. Flowers: 2.6–8.2 cm across, with 4– 8– 11 satiny deep-blue to violet, to indigo-purple, more rarely pinkish, or very rarely light blue petals.

Agastache parvifolia is a species of flowering plant in the mint family known by the common name small-leaf giant hyssop. It is endemic to far northern California, where it grows in woodlands. It is an uncommon species and is sometimes considered a local subspecies of Agastache urticifolia. This plant is an aromatic perennial herb producing an erect stem with triangular serrated leaves on petioles.

Basal leaves are oblanceolate in shape and have petioles. Cauline leaves, those growing along the stem, are ovate to ovate-lanceolate in shape, with alternate attachment to stem, sessile, acuminate at the base, acute at the tip. Leaf margins are entire, or smooth and lacking teeth or serration. Leaf texture is sericeous adaxially (above) and abaxially (below), giving the leaves a silvery-grey appearance.

Zamia fischeri has a subglobose subterranean stem about 8 cm in diameter. Zamia fischeri has a large stem and cones compared to its leaf size. The cataphylls are ovate, 1 to 1.5 centimeters long, and 1.5 to 2 centimeters wide. The leaves are about 15 to 30 centimeters long; the petioles are 5 to 10 centimeters long, and the rachis has 5 to 9 pairs of leaflets.

Flower of D. kenneallyi Drosera kenneallyi is found in sandy loam soils on the margins of the Airfield Swamp. The type material was collected under a Eucalyptus latifolia near the Airfield Swamp. During January and February, this species is frequently flooded with high-temperature water. It survives these conditions by altering the position of its petioles with the rise and fall of the surrounding water.

The basal leaves have fleshy oval blades with bristly, toothed edges which are borne on petioles. Leaves farther up the stem are lance-shaped with smooth or wavy edges and bases that clasp the stem. Flowers occur at intervals on the upper stem. Each has a bell-shaped calyx of bristle- lined purple sepals with four purple tipped yellow petals emerging from the tip.

The plants that do not die completely may have rotted-out, cavernous roots. Various pathogens can cause root rot in beets; however the black streaking on petioles and necrotic vascular bundles in roots and adjacent pink tissue help to distinguish this disease from others such as Fusarium Yellows. Additionally, sampling from the rhizosphere of infected plants and serological tests can confirm the presence of Erwinia caratovora subs.

Pectobacterium carotovorum subsp. betavasculorum is a gram negative, rod bacteria with peritichous flagella. For it to enter sugar beet, and thus cause infection, it is essential that there is an injury to the leaves, petioles or crown. Infection will often start at the crown and then move down into the root, and can occur at any point in the growing season if environmental conditions are favorable.

It was classified in the genus Erwinia until genetic evidence suggested that it belongs to its own group; however, the name Erwinia is still in use. As such, the disease is sometimes called Erwinia rot today. It is a very destructive disease that has been reported across the United States as well as in Egypt. Symptoms include wilting and black streaks on the leaves and petioles.

The 1 in flowers are inflated and have two lips, ranging in color from brick-red, rose- red, to scarlet, and are carried on many 15 in racemes. The calyx is a showy dark-red, about . The stems and petioles of the leaves have short wooly hairs, making them appear gray. The rough leaves are evergreen, with veining on the underside and light cream-colored hairs.

Its petioles are 2-7 millimeters long.

Borassoid palms typically have large, column-like trunks, though several species of Hyphaene have branching or clustered stems. The leaves are large, palmate and often with spines or sharp edges along the petioles. Leaves are retained on young palm stems, later falling to reveal prominent scars. All genera in the Borasseae are dioecious, with separate male and female trees; they are pleonanthic, flowering regularly for many years.

Leaves are sessile (=without petioles), thick and leathery, dark green on upper surface but much lighter below, elliptic to broadly ovate, up to 8 cm long. Peduncles are usually 12–32 mm long, sometimes up to 40 mm. Inflorescence is an elongate raceme up to 40 mm long at flowering time, with 9-27 flowers. Flowers are tubular, greenish-yellow, up to 9 mm long.

Micranthes odontoloma is a species of flowering plant known by the common name brook saxifrage. It is native to much of western North America, where it can be found in many types of moist and rocky habitat types. It is a perennial herb growing from a caudex and rhizome system. It produces a clump of leaves with rounded, toothed, or scalloped blades on long, thin petioles.

They are elongated, and normally located on one side of a vein. More rarely, they may be in pairs on a single vein, but then they never curve over the vein. A flap-like indusium arises along one edge of a sorus. The leaf stalks (petioles) have two vascular bundles, uniting to form an X-shape in cross-section towards the tip of the leaf.

The tree grows with a twisted trunk of to varying heights of . It has needles on the branchlets, aged limbs and trunk. Its leaves are large with petioles in the shape of wings, a dull green colour, and an elliptical or oblong egg shape. The flowers are sweet- smelling, and fruits are formed in globular, egg, or pear shapes, with the width varying from .

The oval to rounded leaves are up to 7 centimeters long and are sometimes borne on petioles. The inflorescence is a raceme of flowers with a distinctive pair of bracts completely fused around the stem to form a rounded disc up to 4.5 centimeters wide.

P. rufescens workers in western and southwestern Europe are dark red, while eastern specimens are more orange-red. Darker ants often have a purplish or brownish tinge to their gasters and appendages. Morphologically, ants of this species are similar to the Mexican Polyergus topoffi, but have narrower heads and petioles and the first tergites of their gasters are more hairy. The total length of this ant is .

Females lay eggs in groups of 1 to 4 on sides of a plants leaves. The caterpillars look like bird droppings and spend majority of their life cycle on leaves, feeding on them in the evening. When the caterpillars mature they start feeding during the day as well by eating leaf petioles or stems. Their hosts are typically Gossypium thurberi, Rhus trilobata, Arctostaphylos pungens and Rhus choriophylla.

Erythranthe tilingii is a rhizomatous perennial herb growing 2 to 35 centimeters tall. The oppositely arranged oval leaves may be several centimeters long and some are borne on short petioles. The yellow flower may be over 4 centimeters long, its narrow tubular throat opening into a wide, two-lipped mouth. The base of the flower tube is encapsulated in a calyx of sepals with uneven lobes.

Banksia blechnifolia is a prostrate shrub that grows to about high and spreads to across. It has thick horizontal stems up to long and thick that lie on top of the ground. They are covered in fine rusty- brown fur, which turns grey with age. The leathery herringbone leaves rise vertically from the stems on thick long petioles, which have two narrow ribs on the undersurface.

It is quite variable in appearance, and submerged parts of the plant look different from those growing above the surface or on land. In general it is a perennial herb growing from a white or blue-tinged tuber. The leaves are variable in shape, many of them sagittate (arrow-shaped) with two smaller, pointed lobes opposite the tip. The leaf blades are borne on very long petioles.

The leaves are arranged alternately on petioles. They are ovate, long by wide (rarely to by ). They have 6–10 pairs of prominently grooved and slightly downy veins and an entire margin. The flowers are small, in diameter, star-shaped with five greenish-white acute triangular petals, hermaphroditic, and insect-pollinated, flowering in May to June in clusters of two to ten in the leaf axils.

Thalictrum occidentale is a perennial herb growing erect to a maximum height around a meter. It is hairless to lightly hairy and glandular. The leaves have compound blades divided into a few or many segments, often with three lobes, and are borne on long, slender petioles. The inflorescence is an upright or arching panicle of flowers with leaflike, lobed bracts often growing at the base.

The basal leaves have lobed or toothed blades on long petioles, and the leaves higher on the stem have smooth or toothed edges. The inflorescence is a raceme of flowers and bracts. Each flower has a bell-shaped calyx of sepals and four purple petals which may be nearly 2 centimeters long. The fruit is a long, flattened silique up to 14.5 centimeters in length.

It is native to the southeastern United States, where it is distributed in Alabama, Florida, Georgia, Louisiana, and Mississippi.Biota of North America Program 2014 county distribution map Brintonia discoidea is a perennial herb growing up to 1.5 meters tall from a thick rhizome. The erect, unbranched stem is lightly hairy. The alternately arranged leaves have rough-haired serrated blades up to 10 centimeters long on winged petioles.

Pilea pumila is an erect annual, growing 0.7 to 70 cm tall. The foliage is opposite, simple with dentate margins, wrinkly (with depressed veins), ovate, and with long petioles. Both the leaves and stems are translucent and bright green, turning bright yellow in autumn.

The leaves have 18-20 secondary veins emanating from its midrib. Its petioles are 3-6 millimeters long, covered in rust-colored wooly hairs and have a groove on their upper surface. Its flowers are on 1-1.5 centimeter long, black peduncles that are covered in white wooly hairs. The peduncles have a triangular bract about a third of the way up their length.

The leaves are widely linear in shape and borne on short petioles. The top of the stem is occupied by the tall inflorescence, which bears hanging buds that open from the lowest upward so that there are several closed buds above open flowers. The sepals do not remain fused as the flower opens. The petals are diamond-shaped and sometimes lobed and curling at the tip.

The diet of Perrier's sifaka resembles that of other sifakas, consisting of fruit, leaves, flowers, buds, petioles, and seeds. Sifakas are naturally suited for this herbivorous diet because they have long gastrointestinal tracts and enlarged ceca. Groups of sifaka do not show any aggression towards other groups when feeding, let alone come into contact with each other. Sifakas in general show seasonal variation in diet.

The elliptic-oblong, leathery leaves of about 7 to 10 cm long, are carried on long petioles, and are often noticeably folded along the midrib. The leaf sides are almost parallel and clear net-veining is visible on the lamina. Leaves are brittle and have a characteristic smell when broken or bruised.

From the top of the leafy stem appears an inflorescence of tube-shaped reddish-purple flowers, each about a centimeter long. The fruits are bumpy, bristly nutlets attached to each other in clusters of four.

Macrozamia montana is part of the genus Macrozamia but is isolated from the rest of the genus. It is more closely related to larger M. communis plants in New South Wales, Australia than the smaller M. communis plants on the north of Newcastle. The petioles of the M. communis however, grow to about 10–40 cm long which is far longer than those of the M. montana.

It is a bush or small tree reaching 6-7 meters in height. Its black, slender branches have fine dark-red hairs when young, but later become hairless. Its oblong leaves are 3.5 by 13 centimeters with tips that come to a long tapering point and bases that taper to their connection to their petioles. Both surfaces of the leaves are hairless and their margins are wavy.

Eryngium mathiasiae is an erect perennial herb 30 to 40 centimeters tall. There is a basal rosette of long lance-shaped leaves, the blades up to 17 centimeters long and lined with sharp-pointed serrations or lobes, borne on petioles several centimeters in length. The inflorescence is an array of flower heads, each surrounded by sharp, spined bracts. The greenish flower heads bloom in small, white petals.

Betka bottlebrush is an upright or angular spreading shrub which grows to between 1 and 3 metres in height and 1 to 4 metres in width. It has grey bark which reveals white underneath after peeling. Its new growth is initially pink, becoming blue-green and eventually green with a non-glossy sheen. The stiff leaves are irregularly aligned as a result of twisted petioles.

It is a tree reaching 23 meters in height. Its papery to membranous, elliptical leaves are 14-29 by 3.5-11.4 centimeter, have short tapering tips and bases that come to a point where they meet the petioles. The dull upper surfaces of the leaves are hairless except the midribs which have fine hairs. The shiny lower surfaces are hairless except the midribs which have fine hairs.

Cleistanthus sumatranus is an evergreen tree, growing up to tall. The leaves have petioles with elliptical leaf blades which are typically by . Flowers are small, each with five sepals and five small petals (both male and female), with up to seven occurring in axillary fascicles, subtended by normal or smaller leaves, or on leafless spike-like axes. Flowering is typically from March–August; fruiting from April–October.

The plant's apical meristem produces a rosette of pinnate leaves, each with several pairs of leaflets with toothed margins. The lower leaves have short stems, the upper ones are stemless, and the terminal leaves have three lobes. The leaves are once- or twice-pinnate with broad, ovate, sometimes lobed leaflets with toothed margins; they grow up to long. The petioles are grooved and have sheathed bases.

The large shrub or tree up to tall and has a similar width, it has ribbed branchlets that are often arched downward.

It is a small tree. Its wrinkled, hairless, dark brown branches are circular in cross- section and have lenticels. Its petioles are 5-10 millimeters long. Its leathery, elliptical, hairless leaves are 10-25.5 by 3.5-6.5 centimeters with tapering tips and wedge-shaped bases. It leaves have 10-12 pairs secondary veins emanating from their midribs and their smaller veins give the leaves a granular appearance.

The perennial wildflower Trillium cernuum possesses three leaves that are sessile at the top of the stem. In botany, sessility (meaning "sitting", used in the sense of "resting on the surface") is a characteristic of plant parts that have no stalk. Flowers or leaves are borne directly from the stem or peduncle, and thus lack a petiole or pedicel. The leaves of most monocotyledons lack petioles.

Its leaves are triangular- lanceolate, truncate to cordate at the base, with an acute tip. Its petioles are around 10-40 mm. It produces small yellow flowers from late spring through summer. Tragia betonicifolia can be distinguished from the similar looking Tragia urticifolia by its shorter pedicels on staminate flowers (with the persistent base only reaching 0.6 mm), and its more distally clustered flowers in the raceme.

The leaves are petiolate with 2 to 18 cm long petioles. The leaf blade is egg-shaped or round, 5 to 15 cm long and 3.5 to 14 cm wide. The underside is densely hairy with short, soft trichomes, the top is more or less sparsely hairy. The base is heart-shaped, the leaf margin is entire or three-lobed, the tip is pointed or sharply pointed.

The leaves are shallowly, acutely lobed, 7–14% of the way to the central vein. The leaf margins are weakly doubly serrate. The upper surface is dark green and hairless, the lower greenish-white with matted plant hairs and between 17 and 22 veins that project at an angle of 32 to 39 degrees from the central vein. The petioles are 8 to 20 mm in length.

Clarkia borealis is a rare species of flowering plant in the evening primrose family known by the common name northern clarkia.

Water pennywort has stems that spread horizontally and can float on water. Leaves grow on petioles up to 35 cm long, and are round to kidney-shaped, with 3-7 lobes and crenate to entire margins. Flowers are small, pale greenish white to pale yellow, and come in umbels of 5-13. Fruits are small achenes that can float, helping the seeds to disperse.

Lesions can also form on the petioles, stems, flowers, and fruits. The fungal spores are borne on the wind and infect plants when the plant surface is moist and the average temperature is around 10 °C. Symptoms appear in about two weeks and the lesions are largest by 20 to 25 days after infection by spores. Several potato cultivars are resistant to the rust.

Phacelia minor is an annual herb producing a mostly unbranched erect stem 20 to 60 centimeters tall. It is glandular and coated in stiff hairs. The leaves are up to 11 centimeters long with toothed, crinkly, oval or rounded blades borne on long petioles. The showy inflorescence is a one-sided curving or coiling cyme of many bell-shaped flowers, each up to 4 centimeters in length.

Cercospora arachidicola only infects peanut plants, causing symptoms of brown lesions with chlorotic rings on the stems, leaves, and petioles. The first macroscopic symptoms usually appear on the adaxial surface of the lower leaves about 30 to 50 days after planting. Further damage can lead to premature defoliation and even yield loss. Signs include tufts of silvery, hair-like spores on lesions during humid weather.

It is surrounded at the base by narrow oval leaves up to 8 cm (3.2 inches) long, on petioles. There may be a few much smaller leaves along the stem. The inflorescence is made up of 1-3 flower heads per stem, each head lined with hairy, glandular phyllaries. The head contains 15–40 blue or purple ray florets surrounding numerous yellow disc florets.

Dissected terminal bud showing ligulate excresences. The midge induces stunted and distorted rosettesHancy, Page 88 in the host by inhibiting the elongation of the shoot; the rosette is formed from many (8 to 40 or more) slightly thickened and deformed leaves with reduced petioles. Many of the leaves have small green or red ligulate excrescences or projections. The midge larvae are of an orange-red colour.

Drosera regia shares other features with the robust Tasmanian form of D. arcturi, including the lack of stipules and petioles and the non-circinate growth of the scape. It has a diploid chromosome number of 2n = 34, which is unusual for the genus Drosera and closer to the diploid chromosome number of the Venus flytrap (Dionaea muscipula), another member of the Droseraceae.Behre, K. 1929.

The flowers are monoecious, with separate male and female blooms on the same plant.

Papaya ringspot virus is a well-known virus within plants in Florida. The first signs of the virus are yellowing and vein-clearing of younger leaves, as well as mottling yellow leaves. Infected leaves may obtain blisters, roughen, or narrow, with blades sticking upwards from the middle of the leaves. The petioles and stems may develop dark green greasy streaks and in time become shorter.

Sidalcea oregana is usually hairy in texture, the hairs thick and bristly toward the base of the stem. Most of the leaves are located low on the stem, basal or on long petioles. Their blades are usually deeply divided into lobes (see image at left); upper leaves may be divided further into leaflets. The inflorescence is a dense or open spikelike raceme of many flowers.

Blumea, published online on October 24, 2013. These species are united by a number of morphological characters, including winged petioles, lids with basal ridges on the lower surface (often elaborated into appendages), and upper pitchers that are usually broadest near the base. In their original paper defining the N. alata group, Martin Cheek and Matthew Jebb treated N. ceciliae as possibly conspecific with N. copelandii.

Arikanchan is prepared from taro leaves, black lentils paste and spices in mostly the Eastern Terai of Nepal, is traditional and indigenous food. Taro is grown in the Terai and the hilly regions of Nepal. The root (corm) of taro is known as pindalu (पिँडालु) and petioles with leaves are known as karkalo (कर्कलो) and also as Gava (गाभा). Almost all parts are eaten in different dishes.

Phacelia grandiflora is an annual herb with a branching or unbranched erect stem reaching one meter in maximum height. It is glandular and coated in soft and stiff hairs. The leaves are up to 15 centimeters long with toothed, rounded or oval blades borne on long petioles. The large, hairy, glandular inflorescence is a one-sided curving or coiling cyme of widely bell-shaped flowers.

It grows from bulbs up to 4.5 cm in diameter. The slightly glaucous leaves, which usually appear by flowering time, have short petioles and blades (laminae) which are 20 cm long by 10 cm wide. The flowers are umbellate, on a stem (scape) up to 60 cm in height, pale red in colour, with stamens with prominent long filaments. The stamens are yellow in the Ecuadorian var.

Members of the family have the following characteristics, being distinguished by having strongly dimorphic fronds, with the fertile fronds different from the sterile fronds. The rhizomes are long- to short-creeping to ascending, and sometimes stoloniferous (Matteuccia and Onocleopsis). The leaves are strongly dimorphic and the petioles have two vascular bundles uniting distally into a gutter-shape. The blades are pinnatifid or pinnate-pinnatifid.

Calamopityaceae is the largest family of the division of extinct seed-bearing plants (spermatophytes) known as Pteridospermatophyta. This family is characterized by its petioles and specific wood pattern, and it grew only in the Paleozoic era, specifically in North America and Europe. It is divided into three genera based on stem structure: Calamopitys, Stenomyelon, and Diichinia. It was named by Solms-Laubach in 1896.

Colouration of the vegetative parts is variable. The laminae and petioles are often green throughout when produced in shaded conditions and red to purple in plants exposed to direct sunlight. Both lower and upper pitchers are predominantly green to yellow on their outer surfaces, often flecked with red to purple markings on the interior. Wholly red or purple lower pitchers have not been recorded.

Petioles short. Bracteas deciduous, densely silky. Flowers two to three inches long, two to two and a half inches in diameter, always white. In the silvery underside of the foliage, but in nothing else, this resembles R. arboreum; while in the much divided limb of the corolla, the ten-celled ovary, the stout flexuose style and large stigma, it approaches R. Falconeri, but only in those particulars.

Representatives of this species grow as a rosette herbaceous plant that spans from 10 to 29 centimeters. The stem axis alone reaches a length of approximately 2 to 4 centimeters. Its leaves are red, and in the plant's drooping age, the length of the leaves can be 10 to 12 centimeters. The petioles can be 6 to 7 centimeters in length and 1 mm in width.

Sarsaparilla is a perennial woody climber with tendrils, thin branches and extended ovate leaves that grows about 4 to 5 meters vertically. Its paper-like leaves are pinnate veined, leathery and alternatively arranged. The leaves' width ranges from 10 to 30 cm and the petioles' length is about 5 cm. It is known for its small red berries with 2 or 3 seeds and small green flowers.

Flower of Drosera nidiformis Leaves on mature specimens are obovate and range from 1 to 2 cm in length. Petioles can grow 1.5 to a maximum of approximately 5 cm. D. nidiformis exhibits a reddish tint if grown in the correct light conditions. Upon capture of prey, the leaf curls around it to bring it into contact with as many digestive glands as possible.

Its base is a caudex which is generally covered in the remains of withered leaf bases. The leaves have lance-shaped or oblong blades which have smooth or toothed edges or may be divided into a few lobes. The blades may be 22 centimeters long. Some are borne on long petioles, while others, especially those higher on the plant, clasp the stem at their bases.

This may deter predators, keep out water and/or keep out chilled air (the latter is Darwin's preferred function). Leaves are dragged in mostly by the tips, which is the easiest way of doing it, but when the base is narrower the worms change behaviour. They drag pine needle clusters in by the base. Petioles are used to plug up burrows, and for food.

This also makes it burp frequently from the resulting gas. It prefers to eat small, young and tender leaves, but will also eat fruit like figs, buds, petioles, flowers, bamboo shoots and seeds. It gets all the liquid and protein it needs from the food it eats and doesn't need to descend to the ground to drink. This monkey eats 50 different plant species but no animal prey.

The basal leaves have fleshy oval blades up to 3 or 4 centimeters long borne on petioles, with leaves farther up the stem smaller and simpler. The inflorescence is a single flower head, or occasionally two to five heads. Each is lined with reddish or green phyllaries with green or bluish tips. The head contains many golden yellow disc florets and usually 13 yellow ray florets each roughly a centimeter long.

Melaleuca adnata is an erect to spreading shrub up to tall with papery or fibrous bark. Its leaves are arranged in alternating pairs at right angles to the pairs above and below so that there are four rows of leaves along the stems. The leaves are elliptic to narrow egg-shaped, long, wide and crescent-shaped in cross-section.The petioles are attached the underside of the leaves (peltate).

Packera ganderi is a perennial herb producing a single erect stem which grows to a maximum height of 50 to 80 centimeters. It is mostly hairy and green, but may have some fuzzy areas and a purple tinge. The leaves have rounded or oval blades with toothed edges or shallow lobes. The blades are often thick and somewhat tough, measuring a few centimeters long and borne on petioles longer than themselves.

It is endemic to Wyoming in the United States, where it occurs only in and around the Wind River Range in Fremont County. This species is a perennial herb growing from a taproot and producing decumbent or prostrate stems up to 15 centimeters long. The basal leaves are up to four or five centimeters long with oval blades borne on petioles. Longer, narrower leaves occur along the stems.

The virus can also cause malformed leaflets, crinkled leaves, and also uneven leaf distribution in the plant. Another symptom can be the formation of lesions or areas of damage in the petioles and stolons of the plant. Episnasty can also occur from the virus, which causes increased growth of the upper region of the plant, which in turn makes the plant top-heavy causing it to bend downward.

It can grow up to 20 m (65 ft) in height and up to 60 cm (24 in) in diameter. The bark is grayish brown. The leaves are oppositely arranged, toothed edge, oblong and lanceolate shaped. 7-15 long, 2–4 cm wide, with the apex and base acute. Glossy green above and whitish and somewhat hairy below, the petioles are fluted and hairy about 0-7-1 cm long.

This is a tough perennial herb growing from a woody rhizome. The thick, leathery leaves are oval in shape and up to about 30 centimeters long including the petioles, located in a basal rosette about the stem. The inflorescence is a stiff, branching panicle no more than about 35 centimeters tall bearing large clusters of flowers. The flowers have brownish white ribbed sepals and lavender to nearly white petals.

Stipules are linear, measured approximately 1.5 cm in length. Both stems and petioles (3–11 cm in length) are smooth or generally free from hair. Acetosella is further divided into a section called Furcaria, which is a group of approximately 100 species that have non-fleshy calyx or sepals. The sepals contain 10 veins, 5 of which run to the apices of the segments; the other 5 run to the sinuses.

Packera layneae is a perennial herb producing an erect stem or a small cluster of stems up to 70 centimeters tall. The thick leaves have wide lance-shaped blades a few centimeters long which are borne on long petioles; smaller leaves occur farther up the stems. The inflorescence bears several flower heads containing many yellow disc florets and several narrow yellow ray florets each up to 1.6 centimeters long.

The female takes two to three days to construct the flimsy platform nest. It is made of twigs and leaf petioles that are carefully selected by the male (as in other dove species) and delivered to her at the nest site. The nest is placed 2 to 10 meters above the ground on a horizontal branch fork. Quite often, an old nest of another species may be used.

Its petioles are 3-7 by 1.2 millimeters and covered in sparse, fine hairs. The flowers are on fleshy, densely hairy pedicels that are 2.5-5 by 0.5-0.9 millimeters. The pedicels have an oval, basal bract that is 1 by 1 millimeters, and another upper bract that is 1-1.5 by 1-2 millimeters. Its flowers have 3 oval sepals that are 1.5-2 by 2-2.5 millimeters.

Trachymene ochracea is an erect herb growing up to high. The leaves are consist of 3-5 deeply dissected lobes on stalks (petioles) up to 10 cm long. The inflorescences are umbels borne on dichasial cymes. The umbels have 30 to 60 flowers, are from 7 mm to 18 mm in diameter on stalks (peduncles) which are 3 to 8 cm long and are glandular- hairy near the stalk base.

In clasping or decurrent leaves, the blade partially surrounds the stem. When the leaf base completely surrounds the stem, the leaves are said to be perfoliate, such as in Eupatorium perfoliatum. In peltate leaves, the petiole attaches to the blade inside the blade margin. In some Acacia species, such as the koa tree (Acacia koa), the petioles are expanded or broadened and function like leaf blades; these are called phyllodes.

Buddleja longiflora is a shrub 0.5 - 1 m high. The young branches are densely tomentose, bearing lanceolate leaves 10 - 17 cm long by 1.2 - 2.7 cm wide, glabrescent above, tomentose below, with petioles 1 - 2.5 cm long. The yellowish orange inflorescence is < 15 cm long, the flowers borne in paired 3 - 5 flowered cymes. The eponymous long flowers have corollas 35 - 42 mm long by 4 - 5 mm wide.

Livistona nitida has cream to yellow flowers, flowers from September to December, and fruits from November to March. It is a dioecious palm, growing to 35 m, with raised leaf scars. The petioles of dead leaves persist for the first metre, but they shed higher up the stem.

The flowers are green, brown, yellow, pink, or purple and have narrow sepals and petals.

Injury to the leaves, petioles or crown is mandatory for the pathogen to gain entry to the host tissue. Accordingly, hail damage is correlated with a higher degree of disease outbreak. Young plants (less than eight weeks old) are also considered to be more prone to infection Temperature and availability of moisture are key factors in determining the rate of disease development. Warm temperatures, 25-30 °C, promote rapid disease development.
