The sand wasp Ammophila sabulosa has an exceptionally long petiole. This Acanthomyrmex ant has a petiole and postpetiole In entomology, petiole is the technical term for the narrow waist of some hymenopteran insects, especially ants, bees, and wasps in the suborder Apocrita. The petiole can consist of either one or two segments, a characteristic that separates major subfamilies of ants.
|
|
There is a notably large backward curving spine formed from the upper surface of the petiole, being longer than the width of the petiole.

Saccoloma inaequale petiole Image at PlantSystematics.org 01 Feb 2012Saccoloma dominguense petiole Image at PlantSystematics.org 01 Feb 2012 The common name soralpouch fern is used for Saccoloma.
|
|
Broadly oblong oval, obtuse to blunt pointed apex, margins coarsely serrated; petiole channelled above in mature leaves; prominent fleshy horseshoe-shaped cushion on upper side of petiole of young leaves.

|
The overgrown petioles of rhubarb (Rheum rhabarbarum) are edible. Petiolated leaves have a petiole (leaf stalk), and are said to be petiolate. Sessile (epetiolate) leaves have no petiole and the blade attaches directly to the stem. Subpetiolate leaves are nearly petiolate or have an extremely short petiole and may appear to be sessile.
|
|
The petiole is thick and hairy, and about long. The leaf is deeply indented where it is attached to the petiole. Opposite some of the junctions formed by the petiole and stem, grow branched tendrils, and at others there are flower shoots. The flowers are monoecious, with separate male and female blooms.
|
|
Both are features seen in ant species that typically soil or leaf litter dwelling. Due to positioning of the worker in the amber, two of the important features distinguishing the subfamily Aneuretinae genera are not directly visible. An elongated one segmented petiole is indicated by the lower impression of the petiole in the amber, though the upper portion of the petiole along with the upper portion of the mesosoma after the pronotum are missing from the specimen. Though the junction of the petiole with the gaster is missing, the lower impression of the petiole shows it was probably widening at the junction.
|
|
The petiole ranges between long and is notably very hairy. It bears a stipule up to half the petiole length which hosts many simple straight hairs in addition to some glandular hairs.
|
|
The propodium bulges into a humped upper surface and the connecting area for the petiole is concave. A short neck connects the propodium to a node-like expanded petiole. While the D. pinguis male is the only fossil male described in the genus, the petiole does show similarity to Dolichoderus kutscheri described from Bitterfeld amber in Europe.
|
|
It has an acute-obtuse apex that is occasionally acuminate. The base of the lamina is gradually or abruptly contracted at the petiole. The petiole is canaliculate and up to 15 cm long.
|
|
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.
|
|
The pronotum displays a pair of spines angled upward and rearward and a 40° angle. Both the alitrunk have a notable and coarse reticulated pattern, while the clypeus, petiole, and post-petiole areas are notably smooth.
|
|
The leaves are elliptical or narrow-oblong shaped, tapering into the petiole. The leaf margin is entire or slightly lobed or toothed. The leaves have a base attenuate to petiole and an obtuse or acute apex.
|
|
The petiole is rounded in side view, with a high, thick scale.
|
|
It has an emarginate apex. The lamina is gradually attenuate into a short petiole (≤7 cm). The petiole is decurrent into a pair of wings (≤2 mm wide) that extend over almost the whole length of the internode.
|
|
Where preserved the mandibles comprise less than half the length of the head. The petiole is rounded in side view, with a high, thick scale, and there are visible hairs preserved on the last segment of the petiole.
|
|
In the event of injury to the bark, a milky juice is released. The leaves are alternate and spirally arranged. They are gummy and thick and are divided into a petiole and a leaf blade. The petiole is long.
|
|
The petiole can reach 6–17 cm in length and is also glabrous.
|
|
The poplar petiole gall moth (Ectoedemia populella) is a moth of the family Nepticulidae. It is found in North America, including Massachusetts, New Hampshire and Ohio. The wingspan is 7-8.5 mm. The larvae make petiole-galls in several Populus species.
|
|
Resupinate leaves have the petiole or "stalk" twisted - respuinate flowers twist as they open.
|
|
We tried what result would ensue upon slitting the intumescence of the petiole horizontally.

Diagram of a worker ant (Pachycondyla verenae) Ants are distinct in their morphology from other insects in having elbowed antennae, metapleural glands, and a strong constriction of their second abdominal segment into a node-like petiole. The head, mesosoma, and metasoma are the three distinct body segments (formally tagmata). The petiole forms a narrow waist between their mesosoma (thorax plus the first abdominal segment, which is fused to it) and gaster (abdomen less the abdominal segments in the petiole). The petiole may be formed by one or two nodes (the second alone, or the second and third abdominal segments).
|
|
The gaster is attached to the petiole with a narrow connection on the secong metasomal segment, while the petiole is narrow and tall. A large sting is present and partly extended from the gaster tip. The pygidium has a fine covering of setae.
|
|
The margins are slightly incurved and narrowly decurrent at the base along the petiole. The midrib is raised on both leaf surfaces. Nerves: Lateral nerves 7 to 14 pairs. Petiole slender, 1–3 cm. Panicles glabrous, erect, up to 20 cm long, terminal.
|
|
Leaf of Sabinaria magnifica. Sabinaria magnifica is a single-stemmed palm tree with palmately- compound leaves. The trunk is tall and in diameter. Leaves are borne at the end of a long petiole; the combined length of the leaf sheath and petiole averages .
|
|
It initially bores in the petiole, causing a gall-like swelling. After the last moult, the larva enters the leaf and creates a blotch. The larva mainly feeds and night, and retreats into the petiole at daytime. Pupation takes place outside of the mine.
|
|
The apex of the lamina is acuminate-obtuse, while the base is abruptly contracted where the petiole begins. The petiole itself is up to 15 cm long. It is canaliculate (grooved lengthwise) and typically bears wings that form a partially amplexicaul sheath around the stem.
|
|
The petiole is a triangle in side view, with a high scale, and a rounded apex.
|
|
They believed that ant-like mandibles first appeared before the development of an ant-like petiole, but such case was proven false when it was opposite on S. freyi specimens (ant- like petiole first appeared before the development of ant-like mandibles). Based on drawings, it was suggested that Mesozoic ants had long mandibles with multiple teeth, toothed tarsal claws and a broadly jointed petiole. Examination of collected specimens, however, shows that these ants had very short mandibles, toothless tarsal claws and a separated petiole. S. freyi remained as the sole member of Sphecomyrma until a fossil closely resembling the species was collected in Canadian amber deposits in 1985.
|
|
The leaf base forms a distinctive green sheath around the uppermost portion of the trunk. Known as the crownshaft, this sheath extends down the trunk. The petiole connects the lead base with the rachis. Zona only reported petiole lengths for three of the 10 species, ranging from .
|
|
Petiole may also be used in the context of wing veins, where a wing cell that is ordinarily four-sided is reduced to a triangle with a stalk (the cell thus being 'petiolate'). The stalk at the base of paper wasp nests is also called a petiole.
|
|
Like all Apocrita, gall wasps have a distinctive body shape, the so-called wasp waist. The first abdominal tergum (the propodeum) is conjoined with the thorax, while the second abdominal segment forms a sort of shaft, the petiole. The petiole connects with the gaster, which is the functional abdomen in apocritan wasps, starting with the third abdominal segment proper. Together, the petiole and the gaster form the metasoma, while the thorax and the propodeum make up the mesosoma.
|
|
The petiole-and-bowl segment stands independently of the leaf section, but is positioned to give the impression that the midrib continues into the petiole. It rises approximately 42 inches (110 cm) off the ground, not including the water spigot. The stainless steel petiole structure stands atop a small stone base and supports the main bowl structure, which is made of copper. A thick, slightly irregular, oblong ring of limestone forms the lip of the drinking fountain basin.
|
|
The leaves of Haemanthus species are thicker, opposite, without a distinct petiole, and never form a pseudostem.
|
|
It is characterized by large pinnate-pinnatisect leaves, sparse narrowly triangular petiole scales and caducous membranous indusia.
|
|
It very much resembles a tuft of grass. The 3-10 leaves are pinnate and coloured greyish-green. The 13-20cm long leaf petiole is spineless, bearing only some fibres along the margins at the base. The petiole is 0.4-0.6cm wide and flat on top but rounded elsewhere.
|
|
Variously sized clubbed hairs are scattered along the rear borders of both the gastral tergites and sternites, while similar, but minutely sized clubbed hairs are rarely found on the rear corners of the head. The propodium has narrow lamellae along the posterior sides that project out and then taper towards the rear. The petiole and post petiole segments each have triangular semi-transparent lamellae on the sides, with the post petiole lamellae bracketed by the lamellae projecting from the front of the gaster.
|
|
Workers can be distinguished from other species by the following combination of character states: conspicuous bristle-like setae covering the entire body but most pronounced on the dorsum of the head, mesosoma, petiole and gaster; fine striations on dorsum of the head; integument smooth and shiny with bluish luster most visible on sides of the head; antero–inferior corner of pronotum without tooth-like process; petiole bulging at antero-dorsal corner; insertions of setae on dorsum of petiole raised, papillate. Males are unknown.
|
|
The petiole node is a bit shorter than it is high and has rounded faces on each side.
|
|
The stamens and the stylus are densely hairy. The mostly four to nine in undergraduate rosettes arranged leaves are divided into petiole and leaf blade. The limb of the wild species is green but purple cultivars have been selected for horticulture. The petiole, soft, whitish, is 15 to 25 cm long.
|
|
This leads to a very small petiole and to the gaster being pointed downward. The anal pore then opens ventrally (toward the abdomen) instead of distally. A side view of the body of a T. sessile. It shows that the gaster part of the abdomen is directly above the ant's petiole.
|
|
This species is a perennial herb. Its rhizome is creeping, with a diameter of between , which is densely covered with fibrous remnants of cataphylls. Its leaves are distally huddled, each being between long; the petiole measuring between . Its lamina is linear, measuring between by , and basally gradually tapers towards the petiole.
|
|
Also, the leaves of Virola pavonis are stalked meaning the leaves have a petiole thus meaning it is petiolated.
|
|
There is a covering of fine microtrichia hairs on the petiole and a pair of small setae are situated near the apex. At the front of the petiole there is a narrow attachment area to the propodeum, while the rear is flared into a large attachment to the gaster. The helcium, a small exoskeleton plate between the petiole and gaster, is developed and shows crenelations on the rear edge. There is a small but distinct constriction between the first and second segments of the gaster.
|
|
Harvested rhubarb petioles with leaves attached The petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves, the leaf stalk (petiole) may be long, as in the leaves of celery and rhubarb, short or completely absent, in which case the blade attaches directly to the stem and is said to be sessile. Subpetiolate leaves have an extremely short petiole, and may appear sessile. The broomrape family Orobanchaceae is an example of a family in which the leaves are always sessile.
|
|
Leaves are bluish-green and pinnately compound. Leaves are arranged on a petiole, long, with 6-9 leaflets-(or variously up to 15, 7, 7-opposite, and one terminal), each being . At the base of each pinnate leaf petiole grow two thorns, about long. Bloom time occurs in late April/May to June.
|
|
The gaster is attached to the petiole with an elongated and enlarged connection on the second metasomal segment, while the petiole has a node in the middle. A number of large setae are scattered on the upper surface of the gaster and a large sting is present and extended from the gaster tip.

Lamina membr., glab., ovate to ovate-elliptic to lanceolate, acuminate, tapering to petiole; ± 60-(75) × 20- (35) mm.; margins ± waved.
|
|
The name derives from the Latin angulatus, which translates as "angular", referring to the leaflet arrangement on the leaf petiole.
|
|
The legs are short and have a thick appearance, while the petiole is low and similar in height and length.
|
|
Mr. Lindsay attempted to elucidate the action of the intumescence in raising and depressing the petiole, in the following manner.
|
|
These ants have a two-segmented petiole (a petiole and postpetiole) connecting their abdomen to the thorax. They have 10 segments in their antennae, which end in large segmented clubs. Thief ants possess small stingers on their oblong abdomens. Worker ants have large jaws for carrying food, usually other ants' brood, back to the colony.
|
|
The projection starts near the center of the petiole segment and slopes upward as it progressed to the front of the petiole, ending with a flat front face. The distinct projection is the inspiration for the species name subcuspis, which is a combination of the Latin prefix "sub-" for underside and "cuspis" meaning point.
|
|
The pronotum and propodeum each have convex upper profiles, with approximately 25 concentric striae circling the pronotum. There is a large backward curving spine formed from the upper domed surface of the petiole, being a little narrower than the width of the petiole, and a smaller process is positioned on the forward underside area of the petiole. The worker is incomplete, missing the legs and antenna of the left side plus tip sections of the right legs. The third through end segments of the gaster are shrunken and missing.
|
|
Several leaves containing a petiole form at the base of the plant. The flowers appear as if they are upside down.
|
|
The vaginate sheath of Ligularia is observed in the petiole of cauline leaves as well as in that of radical leaves.
|
|
Phebalium clavatum is a shrub that typically grows to a height of . Its branchlets are covered with pale red glands and silvery, scale-like hairs. The leaves are more or less circular, about in diameter on a cylindrical petiole long. The leaves and petiole are covered with silvery scales and the leaf has a large spherical gland.
|
|
The mandibles have a flare in width near the center of their length and sport between 9 and 10 teeth with the apical three teeth on each mandible blade elongated and slender for grasping prey. The propodium sports short spines on the rear edge, while the petiole two spines which angle vertically up from the petiole face.
|
|
The buds are in the leaf axils. They may be so tiny as to be almost unnoticeable. Holding the petiole of the leaf as a handle, an oval of the main stem is sliced off, including the petiole and the bud. This is immediately slid into the T on the rootstock, before it can dry out.
|
|
These leaves are pale green to yellowish and have wavy margins. They are long and wide with a petiole long. Flowering plants also have a similar leaf on the flowering stem except that it lacks a petiole and is well above ground level. Up to four flowers long and wide are borne on a brittle, fleshy flowering stem high.
|
|
They are arranged alternately on the stems, an arrangement unusual for Hamamelidaceae. The petioles are long and the leaves flutter in even a light breeze, like the leaves of poplars. The poplar petiole is flattened, and in cross section, it is long in the vertical direction. Whether Exbucklandia has the same sort of petiole has not been recorded.
|
|
The larvae feed on Agathis australis. They mine the leaves of their host plant. The mine starts at the tip of the leaf and then heads for the general direction of the petiole, sometimes double-backing along the way. Near the petiole, the host plant forms a gall, creating a sheltered site for the larva to overwinter.
|
|
Young larvae bore in the petiole, bark or a twig of their host plant. This causes the petiole to swell gall-like. When almost fully grown, it moves through the midrib into the blade, creating a small blotch. Finally, an oval excision is made, which the larvae uses to vacate the mine and drop to the ground.
|
|
Its - to -inch-long leaves are attached to the stems without a little stem (petiole) at the bottom of the leaf (sessile).
|
|
The node shaped petiole is shorter than the height, with a helcium that projects of the front face of the gasteral segment.
|
|
Small tree with alternate, odd-pinnate leaves, the base of the petiole hollow, and inclosing the leaf-buds of the next year.

Growing to tall and broad, the subspecies O. triangularis subsp. papilionacea, the purpleleaf false shamrock, is hardy in mild and coastal areas of Britain, down to , and has won the Royal Horticultural Society’s Award of Garden Merit. It is a perennial plant without aerial stem, formed by leaves borne by a long petiole emerging at the ground level of a tuberous rhizome (5 cm long, over 10 - 15 mm in diameter, fully covered with scales). The leaf is formed of three sessile leaflets (or very short petiole), obtriangular to obovate-triangular, glabrous, arranged in the same plane perpendicular to the petiole.
|
|
Eucalyptus leptocalyx is a mallee that typically grows to a height of and forms a lignotuber. It has smooth brownish over light pink bark. Young plants and coppice regrowth have leaves that are arranged alternately, egg-shaped, long, wide and have a petiole. Adult leaves are the same slightly glossy green on both sides, lance-shaped, long and wide on a petiole long.
|
|
Leaves alternating up to the middle of the stem, with 3-4 petiole, rounded-ovate blades measuring 2 1/2 cm long and 18 mm wide. Obtuse at the apex, acute at the base and round at the petiole. Smooth on both sides of the membranous 5 parallel nerves, reddish-purple underneath. Sheaths with petioles measuring 1 cm long, folded and slightly pubescent.
|
|
The abdominal segment connected to the petiole is modified into a postpetiole that is thicker and a little shorter than the petiole, and which has a distinct convex curve to the upper surface. Of similar size as the head, the gaster has a notably enlarged first segment and in the holotype specimen the remaining abdominal segments are withdrawn into it.
|
|
Medicosma heterophylla is a tree that typically grows to a height of . The leaves are simple and trifoliate, the simple leaves elliptical, long and wide on a petiole long. The trifoliate leaves have a petiole long, the leaflets elliptical, long and wide. The flowers are arranged singly or in small groups up to long, each flower on a pedicel long.
|
|
Pestalotiopsis palmarum is the causative agent of a fungal disease of bananas, coconut and Date palms . The fungus causes leaf spots, petiole/rachis blights and sometimes bud rot of palms. Unlike other leaf spot and blight diseases, Pestalotiopsis palmarun attacks all parts of the leaf from the base to the tip. Whereas most diseases only infect the leaf blade or the leaf petiole.
|
|
Melicope broadbentiana is a tree that typically grows to a height of but also forms flowers and fruit as a shrub. The leaves are simple and/or trifoliate and arranged in opposite pairs. The simple leaves are egg-shaped to elliptical, long and wide on a petiole long. The end leaflet of trifoliate leaves is elliptical, long and wide on a petiole long.
|
|
Eucalyptus × balanopelex is a mallee that typically grows to a height of and forms a lignotuber. It has smooth pale grey to brownish bark throughout. The leaves on young plants and on coppice regrowth are dull green, egg-shaped, long, wide and always have a petiole. Adult leaves are lance-shaped, sometimes broadly lance-shaped, long and wide with a petiole long.
|
|
Cross-section of a 'Pascal' celery rib, the petiole Celery was described by Carl Linnaeus in Volume One of his Species Plantarum in 1753.
|
|
Young leaves are distinctive due to it brown lower surface. Apex tapering. Petiole 1.5–3 cm long. The flowers are small, approximately 5-6mm. Bisexual.
|
|
There is a fringe of long setae along the apical margin of its wing. Its abdominal petiole is dorsally smooth, with deep, longitudinal grooves ventrally.
|
|
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.
|
|
The tiny seeds are explosively expelled. Plants acaulescent or nearly so. The stems, if any, are very short and covered with persistent petiole bases. Leaves are often very numerous and crowded. Stipules persistent; petiole 8–25 cm. Leaf blade long-petiolate, oblong-ovate, deltate- ovate, or orbiculate, entire or deeply pinnately or almost palmately lobed, 6-20 × 7–22 cm, sparsely scabrous or pubescent.
|
|
Unlike all other ant mimics from the family Theridiidae, A. formicaria mimics the ant's petiole by an elongation of the pedicel. In addition the dorsum of the "petiole" is rugose and has a distinct "node", like most ants do. The abdomen is rounded and highly shiny, mimicking an ant's gaster. The spider mimics the 2.6 mm long myrmicine ant Monomorium croceiventre, which lives in the same habitat.
|
|
Eucalyptus beyeriana is a tree that grows to a height of and forms a lignotuber. It has rough, dark grey to black "ironbark" on its trunk and branches. The leaves on young plants and on coppice regrowth are lance-shaped, long, wide and have a petiole. Adult leaves are lance-shaped, long, wide on a petiole long and the same dull green on both sides.
|
|
The fruit is a red hip 1–2 cm diameter. The strong, stalk-round branches have an almost bare, purplish-brown bark and there may be many to no curved, stocky, flat spines. The alternately arranged leaves are divided into petiole and leaf blade and a total of 5 to 11 inches long. The petiole and the rhachis are sparsely spiked and glandular-fluffy hairy.
|
|
The petiole is canaliculate and occasionally winged, the wings being around 4 mm wide. The petiole may be up to 18 cm long in etiolated plants, but is more typically up to 10 cm long. It clasps the stem for around half of its circumference and is abruptly decurrent, sending off a pair of low ridges to the node below. Longitudinal and pinnate veins are inconspicuous.
|
|
Leaves are simple, being directly attached to the stem by a petiole (stalk), but unlike the leaves of most flowering plants they have no stipules. The petiole is short or the leaf tapers gradually towards the base. Leaf arrangement is typically alternate but some are opposite or whorled, and there is generally a rosette at the base of the stem. The edges are toothed (dentate) or sawtoothed.
|
|
A piece of L. dorsata nest L. dorsata nests are made of extremely thin material classified as paper. These nests may or may not have a petiole. If there is a petiole present it is covered in a sticky substance that protects the nest against ants, which are brood predators. The nests are a series of combs underneath the leaf, and may be fused.
|
|
Eucalyptus broviniensis is a tree that typically grows to a height of about and forms a lignotuber. It has smooth bark, pale orange when new but fades to grey. Young plants and coppice regrowth have egg-shaped leaves arranged alternately, long, wide and have a petiole. Adult leaves are lance-shaped, long, wide on a petiole long and are the same dull green colour on both sides.
|
|
The males are smaller than the queens, with a total body length between and an overall shiny exoskeleton. There are longitudinal ridges on the propodeum sides, while the petiole is smooth. There is dense pitting on the head and sparser pitting is present on the gaster and mesosoma. Many upright hairs are found on the gaster, petiole scale, upper surface of the mesosoma, and on the head.
|
|
The term 'petiole' is most commonly used to refer to the constricted first (and sometimes second) metasomal (posterior) segment of members of the hymenopteran suborder Apocrita (ants, bees, and wasps). It is sometimes also used to refer to other insects with similar body shapes, where the metasomal base is constricted. The petiole is occasionally called a pedicel, but in entomology, that term is more correctly reserved for the second segment of the antenna; while in arachnology, 'pedicel' is the accepted term to define the constriction between the cephalothorax and abdomen of spiders. The plump portion of the abdomen posterior to the petiole (and postpetiole in the Myrmicinae) is called the gaster.
|
|
The genus Chiropteris was named from fragmentary and whole- plant fossils. It was constituted of a short 25cm long petiole and a 16cm diameter circular leaf.
|
|
The fungus was discovered growing on a dead petiole of moriche palm (Mauritia flexuosa). It differs from other Wardomyces by having conidia that are readily liberated.
|
|
Petiole comes from Latin petiolus, or peciolus "little foot", "stem", an alternative diminutive of pes "foot". The regular diminutive pediculus is also used for "foot stalk".
|
|
The leaves are alternate, simple, 8–13 cm long and 3.5–4.8 cm broad, oblong-lanceolate, with a serrated margin and a 4–7 mm petiole.
|
|
It has an acute apex and an obtuse base. The petiole is canaliculate and up to 5 cm long. It is semi-amplexicaul, but lacks wings.
|
|
The robust long petiole starts wide at its base, and gradually thins along its length before meeting the leaf in the center of the cordate leaf base.
|
|
Alternately arranged leaves with dark green on both side. Stipules are either small or none. Base of petiole swollen to form the pulvinus. Leaf blade is bipinnate.
|
|
Two to four crops of figs can be produced in a year. Subspecies pubipoda is distinguished by having the base of the petiole covered in white fur.
|
|
Eucalyptus redimiculifera is a tree that typically grows to a height of and forms a lignotuber. It has smooth white to grey or pink bark that is shed in long ribbons. Young plants and coppice regrowth have broadly lance-shaped leaves that are up to and wide on a petiole up to long. Adult leaves are lance-shaped, dull to slightly glossy, and wide on a slightly channelled petiole long.
|
|
Eucalyptus melanoleuca is a tree that typically grows to a height of and forms a lignotuber. It has rough black bark on the trunk and larger branches, smooth white bark above. Young plants and coppice regrowth have egg-shaped leaves long and wide on a short petiole. Adult leaves are the same shade of glossy green on both sides, lance-shaped, long and wide, tapering to a petiole long.
|
|
Eucalyptus beardiana is a spreading mallee that typically grows to a height of and forms a lignotuber. It has smooth grey, cream-cloloured or pinkish bark from the trunk to the thinnest branches. Young plants and coppice regrowth have dull, narrow lance- shaped leaves long and wide and have a petiole. Adult leaves are lance-shaped to curved, mostly long and wide, narrowing at the base to a petiole long.
|
|
The lamina or leaf blade is obovate-oblong in shape and measures up to 15 cm in length by 6 cm in width. Its apex is acute to obtuse and may even be slightly peltate. The base of the lamina is gradually attenuate towards the petiole. The petiole (≤4 cm long) is grooved lengthwise and bears a pair of narrow wings that form a semi-amplexicaul sheath around the stem.
|
|
Nest composed of chewed wood fibers A V. vulgaris nest is made from chewed wood fibers mixed with worker saliva. It is generally made of brittle tan coloured paper. It has open cells and a cylindrical column known as a petiole attaching the nest to the substrate. The wasps produce a chemical which repels ants and secrete it around the base of the petiole, to avoid ant predation.
|
|
Their blades are also ovate, though the bases may be cordate to rounded. They measure long by wide, making them often much longer than the basal leaves. The distal leaves are typically sessile, meaning that no petiole is present, though they are sometimes subpetiolate, meaning a very short petiole is present. The blades are ovate to lanceolate, meaning lance-shaped, with rounded bases and are long by wide.
|
|
In lateral view, the peduncle of the petiole is not clearly differentiated, with an abrupt anterior slope of the node. There is also a conspicuous antereoventral projection of the petiole in T. legatus which is absent in T. dux. Tyrannomyrmex legatus has its sting extruded and it is comparable in length with T. dux. It is possible that a fully extruded sting could appear to be longer as in T. rex.
|
|
The lamina is attenuate at its base. The petiole itself is amplexicaul, canaliculate (grooved lengthwise), and up to 7 cm long. Tendrils are up to 30 cm long.
|
|
Katamenes arbustorum can reach a length of in the females, of in the males. The body has a black and yellow pattern. Petiole and postpetiole are strongly divided.
|
|
Full grown trees usually stand 12m tall. Young branches are sparse-adpressed hairy. Leaves are simple, alternate, and distichous. Petiole is 0.5-1.0 cm long, canaliculate and glabrous.
|
|
The petiole is 7 to 10 cm long and winged. It is semi-amplexicaul, with the lower wings being slightly expanded. Tendrils are 25 to 35 cm long.
|
|
It is similar to P. neriifolia, but has a more westerly distribution. P. neriifolia has sessile (no petiole) leaves, which curve upwards and are often somewhat more greenish.
|
|
The blade is borne on a long petiole, with upper leaves having larger petioles than basal. The inflorescence is a dense compound umbel of many small white flowers.
|
|
Venation is pinnate. They have white to rusty complex hairs on the under surface. The petiole is less than a quarter the length of a blade. Stipules are present.

There are several characters which separate Avitomyrmex from other ant genera. The most notable feature is the distinctly slender nature of the queens and workers morphology. This is shown clearly in the shape of the petiole connecting the thorax and the abdomen. While similar to the modern myrmeciine genus Nothomyrmecia of Southern Australia, the two genera are distinguishable by the structure of the petiole, with Avitomyrmex lacking the peduncle seen in Nothomyrmecia.

Army ant Eciton mexicanum workers with N. kronaueri attached between the ants’ petiole and postpetiole. N. kronaueri is noted for its unusual mechanism of phoretic transport - it uses its mouthparts to attach itself to the waist (between the petiole and postpetiole) of medium sized ant workers of the species Eciton mexicanum. Once attached, the beetles appear to mimic the ants' abdomens. To human eyes, this makes it appear that the ant has two abdominal segments, one above the other.

|
|
The leaves are flattened to slightly angular and range from 5–35 mm long and 1–3 mm broad. They are borne singly and are arranged spirally on the stem; the leaf bases are twisted so the leaves lie flat either side of the stem or more rarely radially. Towards the base, the leaves narrow abruptly to a petiole set on a forward-angled pulvinus. The petiole is twisted at the base so it is almost parallel with the stem.
|
|
In both species the pronotum has an upper front surface that is rounded and not angular, lacking a tooth. The petiole is node shaped, separating it from the extinct genus Electroponera that has a much more angular petiole. The rear side of the metatibiae do not have a median tooth, as seen in modern Ectatomminae genera. The gaster is different from the modern Gnamptogenys and Rhytidoponera in that the trapezoid shaped second segment is not notably rounded as in the modern genera.

|
|
It is also monoecious, which basically refers to a single plant that has both female and male reproductive organs on it. It is typically dark green with serrated leaves and has white disc-like glands that appear above and below the petiole where the stem and petiole meet. Tropic croton can be typically mixed up with the Eclipta prostrate plant because of its similar plant structure but in reality the leaves of the Eclipta prostrate are more linear and arranged oppositely, whereas the leaves on the tropic croton are arranged alternately. The tropic croton can also be confused with Sida spinosa in terms of its growth patterns and appearance but it is important to understand that the Sida spinosa lacks the disc-like glands that appear above and below the petiole.

For those not familiar with botanical terminology, a petiole is the portion of the plant that attaches to the base of the leaf and supports the blade A petiole is commonly called a "stem". The blades are considered sub-coriaceous which indicates the leaves are just less than leathery to the touch. The leaves are slightly more glossy on the upper surface than the underside. The lobes at the top of the leaf are sometimes overlapping but also may appear to have a closed sinus.

The gyne for A. longipennis has a total length of , with only one segment to the petiole, while the first segment of the gaster is not constricted as Heer originally reported. Three sets of paired spines are on the propodium, the pronotum, and the petiole, respectively. The head has antennae with elongated scapes that protrude past the rear margin of the head capsule and have flagellomeres that are longer than they are wide. The margins of the compound eyes are rounded and lacking occipital angles.

The gall is almost globular, of about the size of a pea, and is a swelling of the petiole close to the leaf. It is somewhat rugose (wrinkled) longitudinally and of a grayish color. The course of the petiole is generally very distinct along its upper side, being smooth and of a reddish- brown or yellowish color. The cavity is more or less irregular on account of the woody fibers, which run through the walls of the gall and which are not eaten by the larva.

Workers of D. gribodoi are unique (and easily identifiable) among all Dorylus species in having a nearly round petiole in dorsal view and a distinct ridge on the posterior head margin that is laterally developed into tiny horns in larger specimens. D. gribodoi workers of the same size class can be separated from workers of the D. kohli / D. congolensis complex also by the posterior margin of the head being angular in lateral view and not smoothly rounded. Larger D. emeryi workers can be separated from D. gribodoi workers of the same size class by the following features: posterior angles of head drawn out backwards and ventrally, petiole in dorsal view angled at widest point, petiole has several conspicuous erect setae on dorsal surface (which are lacking in D. gribodoi), largest workers have massive heads with width ≤ 3.92 mm. The unique petiole shape of D. gribodoi was recognized by Emery in his original description of D. gerstaeckeri (Emery 1895) and also by Bernard (1952) who described D. lamottei based on workers collected at Mount Nimba in Guinea but failed to realize that these specimens were in fact conspecific with Emery’s D. gerstaeckeri.

Workers of this species is recognized by its finely micro- sculptured integument which is not shiny, rounded anterior inferior pronotal corner lacking a tooth-like process, ventral side of the head lacking any gular striations and long/flagellate pilosity. Males are distinguished by the long fine setae of the second funicular segment, light brown coloration, long narrow parameres, volsella with two small basal teeth and lacking a lobe on the distal edge of digitus volsellaris. Dinoponera quadriceps may be confused with Dinoponera mutica, but has a finely micro-sculptured integument which is not shiny, lacks gular striations and has a petiole which bulges on the dorso- anterior edge in contrast to Dinoponera muticas roughly microsculptured integument, striated gula and petiole with even, non-bulging corners. Dinoponera quadriceps and Dinoponera mutica differ in micro-sculpturing, gular striations and petiole shape.

Their mimicking behavior was discovered by researchers Ernesto Gianoli and Fernando Carrasco-Urra. They carried out observations and measurements in a rainforest located at Puyehue National Park in southern Chile. They sampled 12 different species of host trees with 45 total individual B. trifoliolata vines that had climbed these trees. The two closest leaves in proximity between a pair of the 45 vine-trees were measured, 11 different traits in total: angle, thickness, petiole length, leaflet petiole length, leaflet angle, maximum width, maximum length, area, perimeter, area/perimeter, and color.

The male genitals are diagnostic for the different species. Polistes species have single-layered nests which are shaped like an umbrella, with the cells exposed to the air from the bottom, and no layer wrapping around the nest. The nests are suspended from a surface by a petiole and are constructed from a paper- like substance made of a mix of saliva and wood fibres chewed off old and soft wood or dead twigs. Many Polistes species in general often have nests supported by a longer petiole than those of Vespula.
|
|
It is 12-15mm wide in the middle, but 5-6mm wide at the end where it joins the leaf blade. The adaxial side of the petiole, the upper surface, is flat, and it has scattered appressed hyaline (glassy-looking) scales, with ciliate hairs along their margins. Both left and right edges of the petiole have short, flat, brown, blunt, triangular, 5-8mm long spines down their entire length, these spines reduce in size as they march towards the leaf blade. The sheath is coloured dark, chocolate brown.

Adult leaves are triangular to more or less round, mostly long, wide on a petiole long and usually the same glossy green on both sides.
|
|
Eucalyptus apodophylla was first formally described in 1934 by William Blakely and Wilfred Surrey Jacobs and the description was published in Blakely's book, A Key to the Eucalypts. The specific epithet (apodophylla) is derived from the Ancient Greek words pous, podos meaning "foot" and phyllon meaning "leaf" with the prefix a- meaning "without", possibly referring to the lack of a petiole, although a petiole is usually present. The whitebark belongs to the Subexsertae series and sub-series Applanatae, along with E. bigalerita, E. platyphylla, E. tintinnans and E. houseana.
|
|
The trunks are both solitary and clustering with short internodes, usually covered in spiny, persistent leaf sheaths. The pinnate leaf has a tubular sheath with whorls and scatters of spines and hairy, brown tomentum, the sheath ending in a narrow, armed auricle on each side of the petiole. The petiole is abaxially rounded, adaxially flattened, hairy, and equipped with grapnel spines. The rachis is similarly armed, the leaflets widely spaced to crowded, linear, with one fold, and covered in bristles and scales; the midrib is adaxially prominent, the transverse veinlets are short yet conspicuous.
|
|
The O. spinifer worker is approximately in length, and has a shining exoskeleton of yellowish red to reddish brown tones. The smooth exoskeleton has tiny punctuation found across the top of the head, mandibles, petiole node and the gaster. In contrast the frons, antennae depressions, pronotum, mesonotum and underside of the petiole are distinguished by varying degrees of striation. The head is large with a rectangular outline, being 2/3 longer than wide, with the rear margin of the head wider than the maximum width of the pronotum.

The flower buds are arranged in groups of mostly seven, nine or eleven on a peduncle long, the individual buds sessile or on pedicels long.
|
|
Its size is comparable to ants in the genus Ypresiomyrma. The shape of the petiole, a narrow waist that is located between the mesosoma and gaster is distinct from other species and is similar in structure to the genus Prionomyrmex though the shape and size of the mandibles are distinct. Overall, M. herculeanus was assigned to Myrmeciinae due to its mandible length, despite them being poorly preserved, and due to the appearance of its petiole and propodeum. The legs are long in comparison to its body length, and the gaster is robust.
|
|
Eucalyptus conglomerata is a straggly tree or a mallee, that typically grows to a height of and forms a lignotuber. It has greyish brown, fibrous stringybark over the trunk and most of the branches, sometimes smooth bark on the thinnest branches. Young plants and coppice regrowth have leaves that are glossy green on the upper surface, paler below, narrow elliptic to narrow lance-shaped, long, wide on a short petiole. Adult leaves are lance- shaped to elliptic, the same glossy green on both sides, long and wide on a petiole long.
|
|
The mature leaves on the vine have three lobes with open upper lateral sinuses (spaces between the lobes) of medium depth. The main vein is slightly longer than the petiole (stalk attaching the leaf blade to the stem), and the petiole sinus opens widely. Between the veins on the underside of both the mature and young leaf there are dense hairs that lie flat against the surface. The teeth on the edge of the leaf blade are convex on both sides, medium in size, and short relative to their width.
|
|
Only some petiole tissue has been found; it is classified to be of the Kalymma genus and suggests the plant had large fronds. To identify a genus within this family, this petiole structure and monoxylic wood must be present, as well as a much larger cortex than vascular cylinder. No fossil evidence has been found to describe on their seed and pollen (reproductive) organs, and therefore the species within this family show more variance than other families. A fossil example of a member of the Medullosales, which has similarities to Calamopityaceae.

Oxyepoecus is differentiated from other Solenopsidini by the 11-segmented antennae with a three-segmented apical club, the clypeus with four teeth, and the dentate propodeum. In addition, the petiole and postpetiole nodes are high and often anteroposteriorly compressed.
|
|
In fact, the stridulitrum is absent from all species except P. pulchella, where a vestigial and non-functional remnant is present. Second, he maintained that there was an "absence of any constriction between postpetiole [= first gastral segment] and gaster", when in fact differentiated presclerites are strongly developed on the second gastral segment but are specialized in form and usually concealed by the posterior portions of the sclerites of the first gastral segment. However, Wheeler did recognise that the apparent similarities between his Phrynoponera species and two Indian Pachycondyla (then Bothroponera) species, Pachycondyla bispinosa (bispinose propodeum) and Pachycondyla rufipes (denticulate dorsal margin of petiole), were superficial and possibly independently acquired. Each of these Phrynoponera-like species lack the extremely specialized morphology of the petiole sternite, helcium, and prora, as well as the characteristic 5-spinose petiole node, that are unique and consistent in the female castes of Phrynoponera.

Dipterocarpus geniculatus is a species of plant in the family Dipterocarpaceae. The species name is derived from Latin (' = with bent knee) and refers to the shape of the petiole. There are two subspecies; D. geniculatus subsp. geniculatus and D. geniculatus subsp.
|
|
They have brown, ellipsoid fruits up to long. The specific epithet velutina comes from the Latin meaning "velvety", referring to the petiole. They grow naturally in lowland mixed dipterocarp forests' habitats from sea level to altitude in Peninsular Malaysia and Borneo.
|
|
The laminar apex is acute. The petiole is canaliculate, semi-amplexicaul, and slightly decurrent down the stem. Tendrils reach 15 cm in length and bear numerous extrafloral nectaries. The leaves of climbing stems are similar, but are separated by longer internodes.

Shade avoidance response in adult plants is less commonly studied than it is in seedlings, though adult Arabidopsis show more complex response patterns than seedlings. Shaded adults have elongated petioles at the rosette, smaller leaf blades, and suppressed axillary bud growth. By elongating the petiole sideways, the plant repositions its leaves away from shading plants to absorb more red light, though there is a trade off in leaf size. The leaves can also bend upwards towards potential light sources as a result of higher growth on the underside of the petiole than the top, a process called hyponasty.

Corymbia scabrida is a tree that typically grows to a height of and forms a lignotuber. It has tessellated, pale brown to yellow-brown or orange bark on the trunk and branches. Young plants and coppice regrowth have more or less egg-shaped leaves that are long, wide and hairy with the petiole attached to the underside of the leaf blade. The crown of the tree has both intermediate and juvenile leaves that are the same shade of dull greyish green on both sides, long, wide and rough with a petiole long attached to the underside of the leaf blade.
|
|
The leaves are large, deltoid (triangular), long and broad with a truncated (flattened) base and a petiole long. The leaf is very coarsely toothed, the teeth are curved and gland tipped, and the petiole is flat; they are dark green in the summer and turn yellow in the fall (but many cottonwoods in dry locations drop their leaves early from the combination of drought and leaf rust, making their fall color dull or absent). Due to the flat stem of the leaf, the leaf has the tendency to shake from even the slightest breeze. This is one of the identifying characteristics.

|
It has been demonstrated that seismonastic movement can be inhibited with the use of anesthetics. Using nuclear magnetic resonance, upward movement of water within the pulvinus joint in response to electrical stimulation was observed in the pulvinus at the base of the petiole. Movement of water to the upper or lower part of the pulvinus causes asymmetric swelling therefore causing the petiole to either droop or rise and contributing to the characteristic displacement of the petioles. The transmittance of internal electrical and chemical signals cause changes in the pulvinus which allows M. pudica to respond accordingly to touch stimuli.
|
|
It has an obtuse apex and is abruptly contracted towards the petiole, which is up to 6 cm long and bears a pair of wings (≤5 mm wide). Around three longitudinal veins are present on either side of the midrib. They originate from the wings of the petiole and run roughly parallel to the midrib in the outer third to fourth of the lamina. Pinnate veins are indistinct and reticulate. Tendrils are usually 1 to 1.5 times as long as the lamina and range in diameter from 2 mm near the lamina to 5 mm near the base of the pitcher.
|
|
P. macrosporus galls on a petiole and mid-rib of A. podagraria The gall develops as a chemically induced swelling, arising from the surface of the leaf lamina, veins, mid-ribs, and petiole. On the leaf lamina it forms yellowish bulges standing out on the upper surface, but missing the black sori that are typical of an otherwise similar gall caused by the rust fungus Puccinia aegopodii. On veins, mid-ribs and petioles the gall appears as translucent yellow-white swellings that are often elongated and blister-like. It is particularly apparent in early spring when the greatly distorted leaves first appear.

|
Eucalyptus fracta is a tree or mallee that typically grows to a height of and has hard, grey to black ironbark on the trunk and branches more than in diameter, smooth whitish bark above. Young plants have dull, bluish green, egg-shaped to more or less round leaves that are long and wide on a petiole long. Adult leaves are the same slightly glossy greyish green on both sides, lance shaped, long and wide on a petiole long. The flower buds are arranged in groups of seven on a branched peduncle long, the individual buds on a pedicel long.
|
|
Pulvinus cells are located at the base or apex of the petiole and the flux of water from the dorsal to ventral motor cells regulates leaf closure. This flux is in response to movement of potassium ions between pulvinus and surrounding tissue. Movement of potassium ions is connected to the concentration of Pfr or Pr. In Albizia julibrissin, longer darker periods, leading to low Pfr, result in a faster leaf opening. In the SLEEPLESS mutation of Lotus japonicus, the pulvini are changed into petiole-like structures, rendering the plant incapable of closing its leaflets at night.

|
T. sessile is a small ant that ranges in color from brown to black, and varies in length from to inches (1.5–3.2 mm). When crushed, these ants leave a smell which leads to their nickname "stink ant". The gaster portion of the abdomen sits directly on top of the petiole in the abdomen of this species, which helps distinguish them from other small, dark, invasive ants. A comparison of the side view of the T. sessile (below) and a diagram of the a typical ant body (below) shows how the T. sessile’s gaster sits atop its petiole.

In shade conditions, the genes coding for XTH9, XTH15/XTR7, XTH16, XTH17, and XTH19 are up-regulated and these proteins act to hydrolyze and weaken the cell wall, allowing for expansion of the petiole cells. Like in seedlings, PIF7 is involved in the regulation of petiole and leaf growth due to low R:FR, by up-regulating auxin-related and brassinosteroid-response genes which promote growth. Auxin signalling is also essential to hyponasty, though its role is not yet fully understood. Leaf curling is primarily a response to phytochrome B converting to PR in shade conditions, which promotes unequal proliferation and growth of cells on the upper and lower leaf sides.

T. legatus is most easily distinguished from T. rex and T. dux by differences in pilosity, sculpture and the shape of the petiole and postpetiole. T. rex is almost lacking pilosity on the mesosomal dorsum, while the whole dorsal surface is covered with long erect hairs in T. legatus and T. dux. The foveolation is weaker in T. rex, especially on the mesosoma where the foveae on the mesosoma are small with most interspaces equal or wider than their diameter. T. legatus can be most easily separated from T. dux by the shape of the petiole, which is much more robust in the former.

40, No. 4, Autumn 1970. Trillium undulatum is a perennial herbaceous plant that spreads by means of underground rhizomes. There are three large leaf-like bracts arranged in a whorl about a scape that rises directly from the rhizome. Bracts are ovate, each with a definite petiole.
|
|
The leaves reach of length. They are oval, bluntly-toothed, quite hairy. They have a short petiole and are in opposite pairs up the stems. The inflorescence is composed of large pedunculated hermaphrodite flowers (two to six, or more) growing in the axils of the leaves.
|
|
They fly during the day in the early spring. Their nearly black coloration is undoubtedly an adaptation toward this habit. The larvae feed on Nothofagus dombeyi. They bore into the leaf and from there through the petiole into the supporting branch, eventually reaching the main trunk.
|
|
The leaf blade is simple, and sometimes has three pointed lobes, or rarely, five. It is thickly leathery and its margin is entire. The venation is palmate, with the secondary veins radiating from the apex of the petiole. The stipules are large and coherent; soon falling away.
|

|
|
There is a tendency for the leaves to cluster near the top of the stem or stems. A conspicuous, slightly ciliate bract with 5-9 lobes is located where the leaf petiole meets the stem. This bract wraps around the inflorescence, which consists of a green cyathium.
|
|
Leaves are lanceolate, up to 50 cm long and 10 cm across, narrowing to a petiole below. One umbel can produce as many as 20 flowers. Flowers are white with a slight greenish tinge, the tepals reflexed (curling backwards) at flowering time.Hortipedia, Hymenocallis speciosaSalisbury, Richard Anthony. 1812.
|
|
The leaves are compound in Bischofia, but otherwise simple and usually alternate. Rarely are they opposite, in fascicles, or in whorls around the stem. The leaf margin is almost always entire, rarely toothed. A petiole is nearly always present, often with a pulvinus at its base.
|
|
The species of the subfamily Corispermoideae are all annual plants. Leaves are mostly alternate, sessile or petiole-like attenuate, laminate, scleromorphic.

|
|
Type I physoderm causes conspicuous black pustules on several parts of the plant including the stem, petiole, leaflet lemina, and flowers. Type II physoderma formed abundant resting spores and epibiotic sporangia on seedlings of S. suave. The stems and leaves of this plant are toxic to livestock.
|
|
The larvae are 110–130 mm long. Early instars feed on the surface of the petiole, scratching the epidermis and then perforating the interior. They create sinuous tunnels with irregular borders. These interrupt the flow of water and nutrients, causing premature senescence of the flowers or fruits.
|
|
The leaves are mostly located at the base of the plant. Each has a short petiole and a thick, bumpy blade up to 10 centimeters wide. The leaf is coated in large, stiff hairs with glandular bases. The branching inflorescence bears clusters of very hairy, tubular flowers.

|
|
The leaves are medium green and have a rhombic diamond shape that give it its species name, rhombea. Leaves have a glossy, dark green petiole. The bisexual flowers are 4–5 mm in diameter and yellow-green, in erect umbels. The round fruits are black when ripe.
|
|
The petiole has a triangular outline and is of similar length as it is high. The stipes on the genitalia are rounded at the tips and triangular in shape. They differ from those of F. flori and F. gustawi which have stipes that are less rounded.

|
This eucalypt was first formally described in 1867 by George Bentham who gave it the name Eucalyptus peltata and published the description in Flora Australiensis. In 1995 Ken Hill and Lawrie Johnson changed the name to Corymbia peltata. The specific epithet (peltata) is from the Latin word peltatus meaning peltate, referring to the attachment of the petiole to the leaf blade.
|
|
The leaves grow 2-8cm long and 3-9cm wide with hairs covering both sides of the leaf surfaces (Geethakumary et al). The petiole ranges from 2-10cm long and is also covered in tiny hairs (Lata and Mittal). The seeds resemble those of other fruits in the cucumber family having an elongated football shape and are pointed at both ends.

|
Pterostylis curta has a rosette of between two and six egg-shaped to elliptic leaves, each leaf long and wide. The leaves are dark green, have a distinct petiole and sometimes a wavy edge. A single white and green flower with a brown tip is borne on a flowering spike high, the flower leaning forwards. The flowers are long, wide.
|
|
The petiole mechanically links the leaf to the plant and provides the route for transfer of water and sugars to and from the leaf. The lamina is typically the location of the majority of photosynthesis. The upper (adaxial) angle between a leaf and a stem is known as the axil of the leaf. It is often the location of a bud.
|
|
Structures located there are called "axillary". External leaf characteristics, such as shape, margin, hairs, the petiole, and the presence of stipules and glands, are frequently important for identifying plants to family, genus or species levels, and botanists have developed a rich terminology for describing leaf characteristics. Leaves almost always have determinate growth. They grow to a specific pattern and shape and then stop.

|
Species of Knorringia are perennial herbaceous plants growing to about tall from a slender, often branched rhizome. The stem may be more-or-less upright or decumbent. The leaves are arranged alternately, usually lobed, carried on a short five-sided leaf stalk (petiole) with two distinct wings. The ochreas are long, and form membranous tubes that partly or fully wrap around the stem.

Acanthostichus is a predatory and predominantly subterranean genus of ant in the subfamily Dorylinae. They are found in the New World, from the southern United States to Uruguay, Paraguay and northern Argentina. They are probably common, but due to their subterranean nature, they are seldom collected or seen. Most species are very similar; the petiole is the most important feature in identifying species.
|
|
Female Agromyzidae insert an egg in the leaf tissue using an ovipositor. In the case of P. ilicis this poses a problem, because the leaf of the hostplant is unusually tough. Only during the annual flush in April, May, when new leaves unfold, is oviposition possible. Oviposition is in the underside of the petiole, or the basal part of the midrib.
|
|
The genus is characterized by elongate mandibles bearing a series of minute peg-like denticles that arise behind the masticatory margin, by frontal lobes that are poorly expanded laterally, by large and deep antennal fossae, and by pedunculate petiole, with a poorly defined node. Among Lenomyrmex species, the queen caste has been described only for L. mandibularis, L. wardi and L. inusitatus.

The plants petiole is swelled. The flowers are compactly racemed, and are white-greenish at the center.
|
|
They mine the leaves of their host plant. Very small young plants can be completely defoliated. The mine is at first slender and serpentine. As the larva becomes nearly full grown, it eats out the whole parenchyma of the leaf and sometimes eats down through the petiole of the leaf to the stem, and sometimes also migrates to another leaf.
|
|
It has long, narrow leaves consisting of a thin blade at the end of a long petiole. The inflorescence yields a flower at the end of each of several long peduncles.

|
|
Covered on both sides of the leaf, these spines run perpendicular to and trail adjacently along the main veins. The spines follow or "trail" each other in a linear fashion, extending from the tip of the blade down to the petiole. Because of their inconspicuous location and unique arrangement, these spines have a tendency to be overlooked, especially by newcomers.

|
The antennae are long with 11 segments, and the scape is long. The mesosoma is long and wide. The mesosoma is convex and domed, and the pronotum is short. The petiole is long and in wide, and the gaster is swollen, but this is due to the early taphonomic process (the transition of a decaying organism over time and how it becomes fossilised).
|
|
The plant, reaching around 2 feet, has small alternate leaves resembling those of the genus Mimosa, disposed in two ranges. The leaves are large at the tip and smaller towards the petiole. The leaves are closed at night and are open in the day. Flowers are greenish white, minute and appear at axiles of the leaves, as well as the seed capsules.
|
|
The punctures are from where pilosity arises, and these are often elongated on the dorsal and ventral portions of the head. On the thorax, striae are present, but they are less engraved with fewer punctures than in S. richteri. On the petiole, the punctates are located on the sides. The postpetiole, when viewed above, has a strong shagreen with distinct transverse punctostriae.

The stimulus is transmitted as an action potential from a stimulated leaflet, to the leaflet's swollen base (pulvinus), and from there to the pulvini of the other leaflets, which run along the length of the leaf's rachis. The action potential then passes into the petiole, and finally to the large pulvinus at the end of the petiole, where the leaf attaches to the stem. The pulvini cells gain and lose turgor due to water moving in and out of these cells, and multiple ion concentrations play a role in the manipulation of water movement. Ions cannot easily move in and out of cells, so protein channels such as voltage-gated potassium channels and calcium-permeable anion channels are responsible for allowing potassium and calcium, respectively, to flow through the cell membrane, making cells permeable to these ions.

In the wake of the Assyriologist Pietro Mander, Zuist researchers explain that the grapheme An or Dingir, which means "Heaven" but also generic "divinity", also has the meaning of "spike", "cluster", "petiole" and is also frequently interpreted as meaning "star", "asterism", though these, mul in Sumerian, are more precisely represented by doubling () or tripling the An grapheme. On a philosophical level, its most appropriate rendition is "centre of irradiation" and "navel of the world" (a concept treated by Mircea Eliade), which emanates the web of the world (personified by the goddess Uttu, "Spider", the last daughter of Enki), which connects all things; it is the sacred centre shared by all entities. It is well represented by the Sumerian figurative meanings of the spike composed of many spikelets, the bunch of grapes, and the petiole from which the fruit (metaphor of the world) hangs.
