Cymes solitary, (1-) 2-3-flowered, extra-axillary. Flowers pale yellow, c. 8 mm across, shortly pedicellate; bracts absent. Sepals linear-oblong, basally connate, c. 3-4 mm long, reddish green at acute apex. Petals spathulate, slightly longer than sepals, obtuse. Stamens c. 20, filaments 2-3 mm long; anthers subglobose.

Type: Near Hala, 25 miles north of Hyderabad (Sind), Babu Haig (K, RAW !).

This species seems to have evolved as a result of natural hybridization bet¬ween Corchorus olitorius and Corchorus trilocularis L. It differs from both Corchorus olitorius Linn. and Corchorus trilocularis Linn., in having oblique, obpandurate leaves, abruptly narrowed above middle, cylindrical, 3-5-ribbed rather than sulcate or triangular capsules and ebracteate rather than bracteate flowers.
