Shrub or small to medium tree 1.8–15 m. tall, glabrous; bark greyish white, warty with old swollen nodes. Leaf-blades elliptic, oblong, obovate or oblanceolate, usually yellow-green when dry, (5–)7–17 cm. long, 2–7.3 cm. wide, ± obtuse to distinctly shortly acuminate at the apex, cuneate at the base, often ± coriaceous; venation closely reticulate; petiole 1–1.7 cm. long; stipules 2.5–5 mm. long, the thicker deltoid part often with a few stiff hairs at its apex. Inflorescences supra-axillary (sometimes only slightly so), compact and subcapitate, several-flowered; peduncles mostly stout, compressed, 2–10 mm. long, thickened apically; bracts and bracteoles triangular, keeled, ± 1.5 mm. long, acuminate, very congested. Calyx-tube 0.7–1.5 mm. long; limb 0.9–1.4 mm. long, slightly toothed, the teeth 0.3–0.5 mm. long. Corolla white, sometimes tinged pink in bud, sweetly scented; tube 3.5–5.6 mm. long, densely hairy inside at the throat; lobes oblong-lanceolate to oblong-ovate, 3–5.8 mm. long, hairy inside at least at the base. Anthers with tips just exserted in long-styled flowers, completely exserted and reaching to or nearly to the tips of the corolla-lobes in short-styled flowers. Style 7–7.5 mm. long in long-styled flowers, well exserted, 2.6–4 mm. long in short-styled flowers, included; stigma-lobes linear-clavate, 1.3–2.5 mm. long. Fruit brown when dry but described as green or black, subglobose or ellipsoid, 5–6 (–7 in spirit material) mm. long and wide, sessile. Seeds dark brown, shining, bowl-shaped, longest dimension 3.4 mm., shorter dimension 2 mm., the depression deep and rounded. Fig. 16, p. 163.
