Trees 5-15 m tall. Bark dark gray, smooth; branchlets terete, rugose, puberulous, glabrescent. Petiole 5-7 mm, pubescent; leaf blade dark or purple-green, glossy adaxially, light green abaxially, orbicular or elliptic to oblong, sometimes obovate, 5-9 × 2.8-6 cm, leathery, both surfaces glabrous, but sometimes puberulous along margin, base broadly cuneate, apex acuminate or acute, apiculate; lateral veins 15-20 pairs, more conspicuous abaxially, veins and veinlets slender, subparallel, obscure. Inflorescence terminal, a loose panicle of umbels, many flowered. Flowers fragrant at night; pedicel 5-10 mm, densely yellow-gray pubescent. Calyx yellowish green; tube narrowly campanulate, 5-6 mm, exterior and interior densely pubescent; lobes 5, ovate, 3-5 mm, both surfaces pubescent, apex rounded and obtuse, or acute. Petaloid appendages 10, scalelike, inserted at throat of tube, obviously densely pilose at anthesis. Stamens 10; filaments ca. 1 mm; anthers linear-oblong, ca. 1.5 mm. Ovary ovoid, densely grayish white hairy; style obsolete or nearly so; stigma capitate. Capsule shortly stipitate, ovoid, 2-3 × ca. 2 cm, densely yellow pubescent, base tapering, apex apiculate; pericarp thin, smooth when dried. Seeds dark brown, ovoid, ca. 10 × 7.5 mm, white sericeous or glabrous; funicle conspicuous, ca. 1.5 × 0.4 cm, longer than seed, tapered at base, broad and compressed below seed.
