Leaves 6–9 × 3.5–5 cm, broadly elliptic to ovate, the apex broadly obtuse to rounded, the margin flat or slightly recurved, narrowly cartilaginous, the base rounded to cordate; the upper surface at first finely brown-scaly, becoming glabrescent but remaining rather rough, midrib raised at the very base, impressed above, lateral veins 3–7 pairs slightly raised; lower surface with the midrib prominent and raised, the laterals mostly obscure, hardly raised, scales brown-stellate to dendroid from pronounced epidermal tubercles, moderately densely set. Flowers 2–5 per umbel, horizontal to half hanging; calyx a 5-lobed, hairy and scaly disc, corolla white with a pink flush in bud and pink patches at the base of the lobes in the mouth, powerfully scented like hyacinths, glabrous outside; stamens 10, irregularly disposed on the lower side of the mouth; ovary white-hairy, style hairy only for about 4/5 of its length, glabrous at the top.
