Ochrea of Persicaria maculosa Most Polygonaceae are perennial herbaceous plants with swollen nodes, but trees, shrubs and vines are also present. The leaves of Polygonaceae are simple, and arranged alternately on the stems. Each leaf has a peculiar pair of fused, sheathing stipules known as an ochrea. Those species that do not have the nodal ochrea can be identified by their possession of involucrate flower heads.

Tricypha ochrea is a moth in the subfamily Arctiinae. It was described by George Hampson in 1901. It is found in Brazil.
|
|
Each leaf has a large stipule which forms a wide, membranous ochrea. The ochrea is up to 2 centimeters (0.8 inches) long and is persistent, fraying into fibrous, silvery shreds that remain on the plant through the seasons. Flowers occur in the leaf axils. Each is up to a centimeter (0.4 inches) wide with five narrow white or pinkish corolla lobes.

Lineodes ochrea is a moth of the family Crambidae. It has only been recorded from Kauai, Oahu, Molokai and Hawaii, but might be an introduced species in Hawaii. The larvae feed on eggplants.
|
|
Stipules are morphologically variable and might appear as glands, scales, hairs, spines, or laminar (leaf-like) structures. If a single stipule goes all the way around the stem, it is known as an ochrea.

Species of Pteropyrum are shrubs. The few leaves may be arranged alternately or in bundles (fascicled). The ochrea is short. The flowers are small and bisexual, with five tepals, two outer and three inner, the three inner clasping the fruit when it forms.

Chalastra ochrea is a moth of the family Geometridae. It is endemic to New Zealand. It was first described by George Howes in 1911 from specimens collected at Woodhaugh Gardens in Dunedin in February and April. The larvae of this species is brown coloured with distinctive markings.
|
|
The brownish ochrea at the base is up to . The inflorescences grow at the top of the stem and from the leaf axils. The flowers have five pinkish or greenish tepals each a few millimeters long. This plant grows in moist, disturbed habitat types, such as ponds, reservoirs, riverbanks, irrigated fields, and ditches.
|
|
The leaves are alternately arranged, deciduous, and variously shaped. The brownish or reddish ochrea may be leathery to papery. The inflorescence may be a panicle or a spikelike or headlike arrangement of fascicles of flowers. The flower is white, greenish, reddish, pink or purple, with the tepals partially fused together along the bases.

Koenigia phytolaccifolia is a perennial herb up to tall. The lance-shaped or pointed oval leaves are 10 to 20 centimeters long and borne on petioles. The leaves have large stipules which form reddish ochrea up to long. The inflorescence is a long array of branching cluster of many white or greenish flowers.
|
|
Leaves emerge curled slightly and folded in half lengthwise. Leaves have stipules which are widened into membranous ochrea wrapped around the leaf bases. Flowers occur in clusters in upper leaf axils. Each is just under a centimeter wide and has five rounded petals, either white with a green stripe or pink with a dark stripe.
|
|
The hairless, branching stems may root at lower nodes that come in contact with the substrate. The leaves are lance-shaped and up to 8 centimeters (3.2 inches) long by 3 cm (1.2 inches) wide. They have bristly ochrea. The inflorescence is an elongate cluster up to 8 centimeters (3.2 inches) long and contains many pink flowers.

Swamp smartweed, renouée faux-poivre-d'eau In general, Persicaria hydropiperoides is a rhizomatous perennial herb growing upright or erect and approaching a maximum height of one meter (40 inches). Roots may emerge from nodes on the lower stem. The bristly lance-shaped leaves are around 10 centimeters (4 inches) long. The leaves have sheathing stipules known as ochrea.
|
|
The terminal area and basal streaks are pale brown. It lacks all other markings, except a trace of reniform stigma. The hind-wing is pale grey; - ochrea Tutt and intermedia Tutt seem to represent merely the type form when washed with pale ochreous, or with rufous ochreous respectively, this latter is the commonest form in Britain. Flavorufa Tutt is a rare species.
|
|
It may be annual or perennial. Persicaria punctatagrows from a rhizome and produces decumbent or erect stems which may just exceed one meter (40 cm) in length. The branching stems may root at nodes that come in contact with the substrate. The lance-shaped leaves are up to 15 centimeters long and have stipules widened into bristly brown ochrea that wrap around the stems.

Polygonum bidwelliae is an annual herb producing an erect green, wiry, angled stem reaching 20 centimeters (8 inches) in height. The narrow, pointed leaves are oppositely arranged along the stem, mainly on the upper parts of stem branches. The leaves have relatively large stipules which form ochrea that sheath the stem, sometimes hiding the leaf bases. The sharp-pointed stipules are membranous and silvery white.
|
|
Polygonum hickmanii is a small annual plant forming compact patches on the ground, its stem growing no more than about 5 centimeters (2 inches) tall. It is lined with linear leaves especially near the tips of the branches, and has a cylindrical, shreddy ochrea. Solitary flowers occur in the leaf axils. They are only 2 or 3 millimeters long and white or pink-tinged in color.
|
|
Polygonum polygaloides is an annual herb producing slender, wiry green stems 1 to 30 centimeters (0.4–12 inches) in length. The linear or lance-shaped leaves are alternately arranged uniformly along the stem, the ones near the tips of stem branches highly reduced. The leaves have membranous stipules which fuse to form silvery ochrea at the leaf bases. The flowers are mainly located in clusters around the stem tips.

California Native Plant Society Rare Plant Profile It is a resident of salt marsh and other wet coastal habitat. Polygonum marinense is an annual herb producing a ribbed, reddish stem growing prostrate or erect to a maximum height near 40 centimeters (16 inches). The narrow oval or lance-shaped leaves are alternately arranged along the slender stem. Each reddish leaf has a funnel- shaped stipule that wraps around the leaf base to form an ochrea.
|
|
The stems are erect, tough, and unbranched until just below the inflorescence. The junctions of the stems are covered by two fused stipules which form an ochrea, a thin, paper-like sheath - a characteristic of the family Polygonaceae, and fringed above in this species. The stem leaves are alternate and are narrowly ovate–lanceolate and have a rounded or tapered base. The leaf stalks are approximately the same length as the leaf blade.
|
|
The basal leaves have a hairless upper surface but have some hairs beside the veins on the lower surface. The upper leaves are alternate and are smaller and more elongated. Where their stalks meet the stem there is a membranous ochrea formed by the fusion of two stipules into a sheath which surrounds the stem and has a ragged upper margin. The flowers are arranged in much-branched, dense terminal compound panicles.

Smith differentiated C. ocreatus from Cistus symphytifolius (which he called C. vaginatus), noting that it had smaller flowers. The specific epithet ocreatus derives from the Latin noun ocrea, "greave", plus the ending -atus, "possessing or resembling". Although the noun may also be spelt ochrea, the spelling ocreatus was used by Buch in publishing Smith's notes. An alternative name for the taxon derives ultimately from Édouard Spach, who in 1836 published a description of Rhodocistus berthelotianus, including variety leucophyllus.

Polygonum parryi is a small annual herb forming mats or cushions of short, angled stems growing erect up to 7 or 8 centimeters (2.8–3.2 inches) in height. The greenish brown stems are lined densely and evenly with linear, spine-tipped leaves. The lowest leaves are longest, reaching up to 2 centimeters (0.8 inches) long, while leaves near the branch tips are small and scale-like. Each leaf has a thin, wide stipule which forms a fringed, fibrous ochrea around the base of the leaf.
|
|
These leaves are 8-20 in length, 6–13 cm in width, with an upper surface glabrous and the lower with short hispid hairs, with five main veins branching from the base and with a slightly wavy (sinuolate) margin (edge). The base of these leaves is cordate and they end in an obtuse (dull) or acute (sharp) apex (point). There are 1 or 2 small leaves on the stem (of the inflorescence) which have very tiny petioles with a short and membranous ochrea. The plant flowers in narrow greenish-purple panicles which branch in two only on the lower part of the inflorescence.
