Dioecious shrub or tree, 3-30 m high; branchlets often prominently lenticulate, glabrous to tomentulose. Leaves narrowly elliptic to elliptic-obovate, up to 65 mm long, apex acute to apiculate, margins crenate-serrate in upper 2/3, coriaceous; petioles distinct, up to 10 mm long. Male spikes with rachis not or scarcely visible, pubescent, gland-dotted, bracts obtrullate, ciliate, ridged; stamens 5-8, anthers minutely papillose. Female spikes up to 45 mm long, rachis visible, pubescent; style branches 2, flattened. Flowering time July-Nov. Fruit an ellipso-globose drupe, warted, wax-covered.
Male catkins waxy green tinged red before anthesis, rather persistently dense, 8–25(32) mm long; bracts mostly 1.5–2.7 mm long, ovate-triangular to broadly deltate in the upper part, abruptly contracted to the base, the angles often rather sharp, glabrous or ciliolate, generally glandular dorsally; stamens usually 4–7, sometimes up to 10 or more particularly in some lower bracts; anthers sometimes papillose or hairy.
Female catkins dense at first, but the rhachis elongating, becoming lax and up to 3–6(8) cm long in fruit; bracts 1–2.5 mm long, ovate-triangular, sometimes abruptly contracted to a narrow point of attachment, otherwise as in male; bracteoles c. 4, 0.6–1 mm long, ovate to circular, concave, ciliate; style arms 1.2–1.8(2.5) mm long, linear-to lanceolate-caudate, somewhat flattened and serrulate.
Tree or shrub, up to 30 m high with girth up to 300 mm. Leaves broadly cuneate to round at base, distinctly petiolate, blade 32-65 mm long. Catkins green, tinged with purple.
Generally a small forest tree, with a dense crown and light grey, fairly smooth bark, 3–10 m tall, but sometimes a much branched shrub only 1–3 m tall, dioecious.
Fruit 3–4 mm across, globose or slightly depressed-globose, glabrous, sometimes developing a white waxy covering.
Branchlets subglabrous to densely hairy.
