Characteristics

Spreading shrub or small tree 2.4–9(–15) m. tall, with dark grey smooth or slightly fissured bark; shoots densely ferruginous velvety when young, later dark and lenticellate.. Leaf-blades ovate-oblong or elliptic to ovate, 3–17(–26) cm. long, 1.5–10(–14) cm. wide, acuminate at the apex, cuneate to rounded or subcordate at the base, densely pubescent to velvety all over with yellowish hairs; petiole 0.5–1.3 cm. long; stipules with base 2 mm. long and filiform part 0.5–1.2 cm. long.. Inflorescences short, 1–4 cm. long, very densely shortly hairy; peduncle 0.6–2 cm. long, with bracts as in last species; pedicels 0.75–3 mm. long, densely shortly hairy.. Calyx-tube subglobose, densely shortly hairy, 1–1.5 mm. in diameter; lobes linear or oblong, 1.5–6(–8) mm. long, densely hairy.. Buds distinctly apiculate, often the 5 appendages very marked.. Corolla bright green or yellow-green, greenish cream inside, sparsely to densely hairy outside, sometimes only on the lobes, the tube ± glabrous; tube 3.5–5.5 mm. long; lobes narrowly triangular, 4–4.5 mm. long.. Fruit eventually turning brown, subglobose, 2–2.5 cm. long or sometimes asymmetric and ellipsoid if reduced to 1 pyrene by abortion; pyrenes 4–5 normally, up to 1.6 cm. long, 7–8 mm. wide, 6 mm. thick.
