Trees, 7-20 m tall, 12-40 cm d.b.h. Branchlets brownish or dark brown, angled, striate, sparsely lenticellate, rusty tomentose. Leaves alternate; petiole 1-2 cm, plano-convex, rusty tomentose or glabrate; leaf blade glaucous and greenish abaxially, shiny and brownish when dry adaxially, narrowly elliptic to elliptic-ovate, 10-15 × 5-8.5 cm, leathery, rusty tomentose initially but soon glabrate abaxially, triplinerved, midrib impressed abaxially, elevated adaxially, basal lateral veins subopposite, arising (2-)5-15 mm above leaf base, arcuate-ascendant, with additional veins outside, other lateral veins 1 or 2 pairs, arising from middle or above lower 1/3 of leaf blade, transverse veins slender, subundulate, rather lax, connected by veinlets, base cuneate, obtuse, or rounded, apex abruptly shortly acuminate. Panicles axillary or terminal, 2.5-8 × 4-5 cm, pedunculate, densely many flowered, brown pubescent. Pedicels short, less than 1 mm, densely brown pubescent. Flowers white, ca. 4 mm. Perianth densely pubescent outside and inside; perianth tube turbinate, short, ca. 2 mm; perianth lobes ovate, ca. 2 mm, acute. Fertile stamens 9; filaments villous, ca. twice as long as anthers, those of 3rd whorl each with 2 clavate glands at base, others glandless; anthers 2-celled; cells of 1st and 2nd whorls introrse, those of 3rd whorl extrorse. Staminodes sagittate, long stalked. Ovary clavate, ca. 2 mm; style linear; stigma inconspicuous. Fruit brown-yellow initially but dark black when mature, glaucous, oblate, 1.2-1.8 × 1.5-2.5 cm, smooth, inconspicuously angled, conspicuously apiculate at apex. Fl. Apr-Jun, fr. Jul-Nov.
