Trees small, ca. 10 m tall. Young branchlets stout, glabrous; old branchlets lenticellate. Leaves clustered at branchlet apex, biennial; petiole stout, 1.5–2.2 cm; leaf blade yellow-brown after drying abaxially, dark green and shiny adaxially, dark green after drying, elliptic or obovate-elliptic, 11–15 × 4–6 cm, thinly leathery, glabrous abaxially, midvein convex abaxially, concave adaxially, lateral veins 8–10-paired, slightly convex abaxially, indistinct adaxially, base cuneate, usually decurrent, margin flat, apex strongly narrowed, shortly triangular cuspidate, rarely acuminate. Flowers not seen. Infructescences terminal, paniculate, 6–10 cm, with 8–10 branched corymbs; primary peduncle very short; primary axis 5–7 cm; secondary peduncles 4–5 cm, distal ones shorter, apical ones ca. 1.5 cm; tertiary peduncles 1–1.5 cm; pedicels 4–6 mm. Capsule subglobose or long ovoid, 5–7 mm in diam, dehiscing by 2 valves; pericarp thin, horizontally small striate adaxially; placentas at base of valves. Seeds 2–4(or 5), black after drying, compressed globose, ca. 4 mm in diam.; funicle very short. Fl. Jan–Mar, fr. Feb–Oct.
