Stems softly woody, up to 10 cm. in diameter at base; bark grey to brownish black, longitudinally striate, glabrous, rarely pubescent, with large leaf scars on young branches but very rarely with protuberances; sap copious, clear; pith wide, spongy, or stems hollow in centre.
Morphology Leaves
Leaves:stipules brown, fused almost to the apex, 6–10 mm. long, pubescent on the midnerves to subsericeous outside, glabrous inside; petioles 2.5–6 cm. long, glabrous to pubescent, rarely with a few stinging hairs, which are sessile or raised on protuberances up to 0.5 mm. high; lamina coriaceous, elliptic to ovate, rarely obovate, (4–)6–12 cm. long, 3.5–8 cm. wide, base cuneate, truncate or rounded, rarely subcordate, margin entire, apex acuminate to caudate; lateral nerves 2–3(–4) pairs, the basal pair extending into upper 1/3 of lamina, all interconnected by scalariform tertiary nerves; upper surface glabrous, rarely with a few scattered stiff hairs, numerous elongated cystoliths present, lower surface glabrous, occasionally pubescent or with scattered, stiff and perhaps stinging hairs, especially on the lateral nerves, rarely with stinging hairs raised on protuberances up to 0.8 mm. high.
Morphology Reproductive morphology Inflorescences
Male inflorescence lax, paniculate, ±6.5 cm. long, with flowers densely clustered at intervals along the axes; peduncle mostly with a few stinging hairs; ♀ inflorescence lax, paniculate, ± 2 cm. long, with small cymose clusters of flowers, peduncle with stinging hairs, especially around the clusters of flowers.
