Shrub or small tree, generally to 2 m, exceptionally to 7 m, usually terrestrial, young stems at first covered in raised discoid scales, later rough with the persistent tubercular scale bases. Leaves 2-4 x 1-2 cm, elliptic, broadly elliptic or obovate, the apex broadly pointed, rounded or retuse, the margin slightly recurved to strongly and broadly turned down to give the leaf a reverse channelled appearance, the base broadly tapering; upper surface at first finely set with golden discoid scales, later glabrous, midrib narrowly impressed, lateral veins 2-4 pairs hardly impressed, often obscure; lower surface with the midrib slightly raised, lateral veins very slightly raised, rather obscure, scales well spaced, discoid with broad centres. Flowers 2-10 per umbel, from terminal and lateral buds, erect to half hanging; calyx a low scaly and hairy ring; corolla red, cylindrical to narrowly funnel-shaped, 1.6-2.5 x 1-1.5 cm, sparsely scaly and hairy outside; stamens 10, more or less evenly distributed around the mouth; ovary densely scaly but without simple hairs, style with a few scales at the very base but otherwise glabrous.
