Corchorus is a genus of about 40–100 species of 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
, reaching a height of 2–4 m, unbranched or with only a few side branches. The
leaf are alternate, simple,
lanceolate, 5–15 cm long, with an acuminate tip and a finely serrated or lobed margin. The
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 into 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.[B. A. Whitlock, K. G. Karol, and W. S. Alverson. 2003. Chloroplast DNA Sequences Confirm the Placement of the Enigmatic Oceanopapaver within Corchorus (Grewioideae: Malvaceae s.l., Formerly Tiliaceae). International Journal of Plant Sciences 164: 35–41]
The genus Corchorus was first described by Carl Linnaeus in his great work Species Plantarum (1753). It is derived from the Ancient Greek word κόρχορος or κόρκορος (korkhoros or korkoros), which referred to a wild plant of uncertain identity, possibly jute or wild asparagus.

The Songhai people of Mali call it fakohoy.
In India, it is locally known as nalta sag. It is a favorite food during the summer months, especially in Sambalpur and the western part of Odisha. Usually it is lightly sauteed and eaten along with rice or rice gruel.
In the Philippines, C. olitorius is known as saluyot. It is commonly consumed as a leafy vegetable together with .
In Thai cuisine, the leaves of the Corchorus olitorius (locally known as bai po; ) are eaten blanched, together with plain rice congee. The taste resembles that of spinach and Salicornia.
