Branches drying brown. Leafy twigs 2–3 mm thick, ± angular, glabrous (or minutely white puberulous); periderm mostly flaking off. Leaves spirally arranged; lamina oblong, elliptic, subobovate or suborbicular, 2–10(–14) by 1–5(–8) cm, coriaceous, apex short-acuminate (with the acumen usually obtuse), subacute, obtuse or rounded, base cuneate, obtuse or rounded (or subcordate), margin flat or ± revolute towards the base, mostly ± callose towards the base; both surfaces glabrous; midrib flush to slightly prominent or (at least the lower part) ± impressed above, lateral veins (3–)4–8(–10) pairs, the basal pair distinct, to (⅕–)¼–⅓(–½) the length of the lamina, departing 1–2 mm above the base of the lamina, unbranched, straight (or, in broadly elliptic to suborbicular laminas, curved), without smaller lateral veins below the main pair, tertiary venation largely parallel to the lateral veins; waxy gland at the base of the midrib; petiole 0.5–1(–3) cm long, 1–1.5 mm thick, glabrous (or minutely white puberulous), drying blackish to brown; stipules 0.5–1(–1.5) cm long, often ± involute when dry, glabrous (or minutely white puberulous), caducous. Figs axillary, paired (or solitary), sessile; basal bracts 3, 2–3 mm long, (sub)equal, glabrous (or minutely white puberulous), persistent or caducous; receptacle subglobose, 0.5–0.8(–1) cm diam. when dry, glabrous (or minutely white puberulous), pink to dark purple at maturity, apex slightly convex to flat, ostiole 1.5–2 mm diam., (almost) flat, open or closed, the 3 upper ostiolar bracts (just) not fully or just fully imbricate, on a low rim; wall smooth; internal hairs present, white, abundant to sparse or absent.
