Leaves imparipinnate, leaf­lets 5-9, acuminate-rhomboid, 5-15 x 4-6 cm, thin, glabrous above, hairy below, caudate-acuminate at apex, unequal sided at base. Flow­ers in terminal racemes of 3-6 large, 10-16 cm wide, white, salver-shaped; calyx conical, beaked, spathaceous, corolla 5-lobed; stamens included in the corolla tube; style exerted. Fruits 30-60 cm long, straight or twisted, capsule with flattened pseudoseptum ; seeds grey, rectangular, in many rows, with corky wings.

Flowering and fruiting from April-August, November-March (West Bengal), May-October(Orissa).
Its flowers open during night and usually fall off at sun­ rise.

The species is rather sporadic and confined to elevated central areas in mangrove forests. It is usually associated with Cerbera manghas, Sonneratia caseolaris and Heritiera fomes, which prefer areas inundated more with riverine water.
