Much-branched shrub 4.5–6 m. tall; stems glabrous, greyish, rather corky and longitudinally rugulose when older.. Leaf-blades oblanceolate-elliptic, 3.5–11 cm. long, 1–3(–4) cm. wide, shortly acuminate at the apex, narrowly cuneate at the base, glabrous; nodules absent but small domatia present; petioles 1.2–3.5(–4) cm. long, relatively long and slender in proportion to the size of the leaf; stipules transversely oblong, 2–3 mm. long, almost immediately deciduous.. Flowers heterostylous, 5-merous, in small few-flowered branched panicles; peduncles 1–1.8 cm. long; secondary branches 0.3–1 cm. long; pedicels 1–2(–3 in fruit) mm. long; articulations of inflorescence margined with sparse ferruginous hairs.. Calyx glabrous, broadly obconic, 2–3 mm. long (mostly limb), subtruncate or very shallowly lobed, the lobes mostly under 0.5 mm. long.. Buds depressed globose, ± truncate, appearing very finely yellowish papillate.. Corolla creamy white; tube 2.2 mm. long, glabrous outside; lobes obovate-oblong, 4.7 mm. long, 2 mm. wide, thick and cucullate at the apex.. Stamens with filaments 0.7 mm. long in long-styled flowers.. Style 3.6 mm. long in long-styled flowers; stigma-lobes 1 mm. long.. Fruits globose or ellipsoid, ± 6–7 mm. long and wide, crowned with 2 mm. long persistent calyx-limb; pyrenes 1/2-ovoid, 6.5 mm. long, 5.5 mm. wide, 3 mm. thick, slightly rugulose particularly on ventral surface but not grooved.. Seed dark red, similar in outline, dorsally quite strongly ruminate, ventrally with a T-shaped groove.
