Panicle large, terminal. Flowers pale yellow, appearing after the leaves, pubescent; pedicel 2-4 mm long, articulate. Sepals nearly free to the base, linear-oblong, 10-12 mm long, c. 2 mm broad, completely reflexed. Staminal column c. 1 cm long, with 10 sessile anthers. Follicles 4-5, each c. 10 cm long, c. 3 cm broad, elliptic-ovate, veined, 2-seeded. Seeds adhering to margins, glabrous, smooth, 4-6 mm in diameter.

    Type: Described from China or Japan, not precisely designated.

    The tree is cultivated in gardens for shade. Immature follicles are filled with a brownish black fluid which is liberated and perhaps cause of dehiscence of premature fruits.
