Leaves coriaceous, oblique ovate-elliptic, (4-)6-10(-13) by (1½-)2½-3½(-5) cm, index 2-3, broadest at or below the middle; slightly dis-colorous, above glabrous, dull grey in drying, beneath glabrous or sparsely rufous-pubescent especially on midrib and nerves, yellow grey-green in drying; base rounded-attenuate, strongly asymmetrical; margin denticulate or distinctly serrate at the upper half, or subentire; apex acute, acuminate, to caudate; midrib and nerves flat to impressed above, raised beneath; nerves 3-4 pairs, ascending and arcuating, anastomosing near the margin, the lowest pair running to c. ⅓-⅔ the length of the leaf; reticulations fine, subscalariform, rather distinct beneath; petiole 5-12 by 1-2 mm; slightly sulcate. Inflorescence ♂ or⚥, cymoid, including the bracts densely rufous-hairy. ♂ Inflorescence borne on the lower and leafless part of the new shoot, 2-5-flowered, occasionally several of them are clustered together on leafless short lateral new shoots giving rise to a raceme of cymes; ♂ flower c. 2-3 mm ø; perianth lobes 4(-5), c. 1½-2 by 1 mm, ciliate; filaments ½-l mm, anthers reniform, c. 1 by ½ mm, sparsely sericeous; pistillode very much reduced. ⚥ Inflorescences 2-5-flowered, axes slender, in the axils of new leaves; ⚥ flower c. 2 mm Ø; perianth lobes ciliate, c. 2 by 1 mm; stamens as in the ♂ flower; ovary ovoid, c. 2 by 1 mm, sparsely minute pubescent; stigmatic arms c. 2 mm long, ½ mm broad, spreading.

Trees, to 30 m tall, deciduous or sometimes evergreen. Bark grayish white. Branchlets densely yellowish brown pubescent when young, brown, usually glabrescent with age; lenticels few or none. Winter buds brown, 1-3 mm; scales glabrous, margin ciliate. Stipules narrowly lanceolate, caducous, to 7 mm, never enclosing buds. Petiole 6-13 mm, brown, broadly sulcate, puberulous at least near adaxial furrow; leaf blade ovate-elliptic, ovate-lanceolate, or ± rhombic, 5-13 × 2.5-5.5 cm, thickly papery to ± papery, abaxially usually inconspicuously yellowish brown puberulent when young, with hairs scattered on major veins and sometimes tufted in vein axils with age, base oblique with one side ± rounded and other cuneate, margin entire or obtusely serrate, teeth 0-13 on each side, apex acuminate to shortly caudate-acuminate; secondary veins 3 or 4 on each side of midvein. Flowers fascicled, occasionally in racemes of 2 or 3 flowers. Style branches linear, undivided. Infructescences unbranched or seldom forked, rarely showing a small scar from a fallen male flower, 1-3 per leaf axil, rather slender, glabrous or pubescent, 0.8-1.5 cm; fruiting pedicel 1 or 2 × as long as subtending petiole. Drupe yellow to orange when mature, ± globose, 7-8 mm in diam. Stone ± globose, ca. 5 mm in diam., 4-ribbed. Fl. Mar-Apr, fr. Sep-Oct.
A medium sized tree that loses its leaves during the year. It grows 15 m high. It has a short thick trunk. The crown is spreading. The bark is bluish-grey. It is smooth and speckled with raised white dots. Old trees develop horizontal wrinkles. Young leaves are pale green. They become dark green later and turn yellow before falling. The leaves are 8-12 cm long on short stalks. There are teeth along a part of the leaf edge. They are pointy at the tip and have 3 veins at the base. The flowers are small and green. Flowers can be male, female or of both sexes. They are in the axils of the leaves at the end of longer stalks. Male and bisexual flowers are at the base of short stalks below the leaves. The fruit are small and berry-like. They are green and turn orange-red. They are the size of a peppercorn and eventually turn black.
