Medium trees, up to 9 m high, branching almost from base, densely foliaged; branehlets spreading, spiny; spines up to 6 cm long. Leaves unifoliolate, up to 12 cm long; petioles winged; wings oblong-spathulate, truncate above, tapering towards base, often larger than lamina, 4 - 6.5 x 1.5 - 3 cm; nervation similar to that of lamina; leaflet blades ovate-elliptic to lanceolate, obtuse to rounded at base, subacute at apex, obscurely crenate along margins, ca 5 x 3 cm, deep green and glossy above, glabrous, coriaeeous, pellucid-punctate, emarginate at tip. Inflorescences axillary, 2 - 8-nate racemes or occasionally of a solitary flower; pedicels slender,5 - 10 mm long, glabrate. Flowers bisexual, sweet scented, ovoid in buds, purplish tinged. Calyx 4-lobed; lobes deltoid, acute, ciliate along margins, scarious, green. Petals 4, ovate-oblong, concave, obtuse, ca 12 x 6 mm, glandular, glabrous, white with purplish, turgid dorsally, Stamens 20 - 23; filaments unequal in length, in groups of 2 or 3, sometimes 1 or 2 free, staminal tube ca 8 mm long, white; anthers ovoid, cordate below, ca 2.5 mm long, yellow, glandular-apiculate. Disk annular, lobed, ca 4 mm broad, whitish. Ovary depressed-globose, ca 2 x 3 mm, greenish, 9 - 11-locular; style ca 4 mm long, cylindric, dilated above, articulate with ovary, white; stigma depressed-globose, as much as or broader than ovary, stieky. Fruits globose to oblate, depressed on both ends, 4 - 8.5 x 4.5 - 10 cm, yellowish, surface pitted or papillate; rind medium-thick, moderately to strongly adherent; mesocarp white, spongy, tasteless; central axis solid; endocarp segments 9 - 15, moderately to strongly adherent, the pulp-vesicles irregular in shape, usually fusiform, greenish- white; juice scanty, white, sour; seeds 30 - 60 per fruit, ovoid, smooth at one side, wrinkled at other, pointed at tip; cotyledons white.
Fl. March-April; Fr. Nov. -Jan.
Distrib. India: Evergreen forests of the Khasi and Naga hills in N.E. India. Meghalaya and Nagaland. Wild and semiwild.
N.Myanmar.
Notes. Fruits are hardly of anycommercial importance. It is reported that the fruits mixed with salt are consumed by the Khasi hill people of Meghalaya.
