Corchorus Tirunelveliensis

''Corchorus'' is a genus of about 40–100 species of flowering plants in the family Malvaceae, native to tropical and subtropical regions throughout the world.

Different common names are used in different contexts, with jute applying to the fiber produced from the plant, and jute mallow leaves for the leaves used as a vegetable.

Description

The plants are tall, usually annual herbs, reaching a height of 2–4 m, unbranched or with only a few side branches. The leaves are alternate, simple, lanceolate, 5–15 cm long, with an acuminate tip and a finely serrated or lobed margin. The flowers are small (2–3 cm diameter) and yellow, with five petals; the fruit is a many-seeded capsule.

Taxonomy

The genus ''Corchorus'' is classified under the subfamily Grewioideae of the family Malvaceae. It contains around 40 to 100 species.

The genus ''Oceanopapaver'', previously of uncertain placement, has recently been synonymized under ''Corchorus''. The name was established by André Guillaumin in 1932 for the single species ''Oceanopapaver neocaledonicum'' Guillaumin from New Caledonia. The genus has been classified in a number of different families including Capparaceae, Cistaceae, Papaveraceae, and Tiliaceae. The putative family name "Oceanopapaveraceae" has occasionally appeared in print and on the web but is a nomen nudum and has never been validly published nor recognised by any system of plant taxonomy.

The genus ''Corchorus'' was first described by Linnaeus in his great work ''Species Plantarum'' (1753). It is derived from the Ancient Greek word or ( or ) which referred to a wild plant of uncertain identity, possibly jute or wild asparagus.
