📚 Overview
Description
Corchorus aestuans is an annual or perennial herb, sublignified branched, erect or spread, reaching up to 1.50 meters high. The stem has a cylindrical cross-section, glabrous with pubescent branches. The leaves are simple, alternate and far from each other. They are characterized by a pair of acuinate stipules and a thin lamina, oval rounded, pointed at the top, three-vein and with 2 red filaments at the base. The flowers are grouped in short inflorescences with opposite leaves. They are golden yellow in colour. The fruit is an erect cylindrical capsule, with 6 to 8 longitudinal ribs winged and ending with 3 to 5 divergent beaks. It contains numerous small pyramidal dark brown to blackish seeds
General habit
Annual or short life perennial herb, sub-lignified branched, erect or spread, which can reach up to 1.50 m high.
Underground system
The plant has a taproot system.
Stem
The stem has a cylindrical cross-section, finely papillose almost hairless surface. It is green in colour often slightly tinged with brownish-red. The branches are pubescent, with simple hairs.
Leaf
The leaves are simple, alternate, spaced. The petiole measures 5 to55 mm. It is small, more or less pubescent, framed by two linear-lanceolate acuminate stipules, 2.5 to 15 mm long, dark red in colour. The leaf blade is thin, shape ranging from elliptic to ovate-lanceolate and suborbicular, narrowed at base, rounded to cordate and sub-acute apex obtuse or acuminate. At the base of the margin, the first tine is extended by a curved filament, purple and 15 mm long. The lamina measures 1 to 10.5 cm long and 1 to 4.5 cm wide. 3 veins comes out of the base. The leaf blade is glabrous on both sides or slightly pubescent. The margin is crenate-dentate in uneven tines.
Inflorescence
Yellow flowers, almost sessile, are grouped by 1 to 3 in short cyme opposite to the leaves.
Flower
The 5 sepals are oblique, cap-shaped, acuminate, smooth, 3 to 9 mm long. The 5 yellow petals are obovate, rounded at the tip, 9 mm long and 3.5 mm wide. The stamens are numerous and free. They are inserted into a cup which is an expansion of the receptacle. The ovary is cylindrical, slightly hairy. It is divided into five loculus each containing many eggs in axillary position.
Fruit
The fruit is an erect cylindrical capsule, extended by 3 or 5 spouts diverging at the apex, narrowed at the base, glabrous. It measures 15 to 56 mm long and 4.5 to 4 mm wide. It has 6 to 8 longitudinal winged ribs which goes from base to summit. The fruit contains a large number of seeds. It is reddish brown when ripe.
Seed
The seed is pyramid-shaped, smooth, dark brown to blackish. It measures 2 mm long and 1.75 mm wide.

Corchorus olitorius exibits significant leaf polymorphism. There are sharply dentated leaves in forms, or even laciniate, whose appearance is very different from the average type. The leaves can also be narrow, resulting in a risk of confusion with C.trilocularis and C. tridens.

Corchorus aestuans is a plant of ruderal areas, along rivers and irrigation canals of rice cultivations.
Mayotte: Corchorus aestuans is an exotic ruderal species that occurs in a wide range of secondarized environments from the driest islets and points to the cultivated and urban areas of the center of the island.
