Shrub or tree (2.0-)3.0-12.0(-20.0) m high; crown spreading or conical with elongate branches; trunk straight, slender, up to 6.0 cm diam; bark thin, grayish to reddish-brownish or blackish, rather smooth. Branchlets rusty-tomentulose at tips. Leaves obovate-oblong to oblanceolate, not rarely elongately so, apex shortly subcaudate-acuminate, base long-attenuate, chartaceous to subcoriaceous, somewhat appressedly short-pubescent on both faces or rarely beneath only, generally glabrescent above, rarely more densely pubescent beneath and remaining so, remotely sinuate-dentate especially in the upper half of the lamina, rarely (sub)entire, 30.0-62.0 cm long, 10.0-22.0 cm broad, lateral nerves 15-20(-25) pairs rather straight below, arcuate and looping before the margin, prominent beneath; petiole markedly thickened and geniculate distally, 4.0-6.0(-8.0, -11.0) cm long; stipules broadly triangular, acuminate, pubescent, 6.0-10.0 mm long, caducous. Flowers polygamodioecious, with a scent of cyanide, clustered generally on defoliated parts of the branches, or on old wood respectively the trunk, rarely in the axils of lower leaves, rusty-pubescent all over in the outer parts; pedicels articulate at base, up to 6.0 mm long. Flowers [male]: sepals 2 or 3, calycoid, whitish-greenish, ovatesuborbicular, sometimes deeply lacerate, 6.0-8.0 mm long, 5.0-6.0 mm broad. Petals (5-)6-7(-10), white to almost cream, outer ones obovate and (5.0-)7.0- 8.0 mm long, 4.0-5.0 mm broad, inner ones gradually narrower, subglabrous. Stamens (20-)35-50, subsessile, hairy, 3.5-5.0 mm long. Rudiment of disk or ovary 0. Flowers 9 : sepals 3, suborbicular, 8.0-10.0 mm long. Petals as in the o' flowers in number, outer ones ca 1.6 cm long, inner ones shorter, sparsely sericeous. Stamens numerous, 4.0-6.0 mm long; filaments up to 1.0 mm long. Disk obsolete. Ovary sessile, ovoid, sericeous, with 9-12 dentate vertical wings; styles 5-6, pubescent; stigmas short, subcapitate. Fruit subglobose to ellipsoid, puberulous, white turning green, 9-12-winged, variable in form and size, 3.0-6.0 cm long, 2.5-4.0 cm thick, the wings soft, with recurvedly dentate, fimbriate or lacerate flattish crests up to 15.0 mm high, tubercled between; pericarp woody-fibrose, 2.0 mm thick; seeds numerous (up to 50), whitish, obtusely angled, 8.0-10.0 mm long, 5.0-6.0 mm broad, in a red or orange pulp.
