Erect or spreading shrub to 2.5 m high. Branches ferruginous-tomentose. Leaves: petiole to 4 mm long; lamina broadly subcordate, to 3 (–6) cm long, papery, sparsely to moderately stellate-hairy on both surfaces. Flowers solitary (rarely 2), terminal to short or slender branchlets; peduncle terminating in a pair of small or foliaceous bracts; pedicel slender, 1–3 cm long, with medial to subapical linear bracteoles 0.5–2 mm long. Calyx hemispherical to cup-shaped, 2–4 mm long, with 4 very narrowly triangular acuminate lobes 3–8 mm long, glabrous or sparsely stellate-hairy outside. Corolla narrowly cylindrical, 2–3 cm long, splitting into petals which enfold stamens, pale green or cream, or mauve with age. Stamens: antipetalous filaments slightly broadened at base; anthers slightly exserted, oblong, narrowing toward apex, c. 2.5 mm long, usually reflexed on margins at anthesis.
