Shrub or small to medium-sized tree 3–15 m. tall; branches spreading horizontally; bark grey; young branchlets pubescent with short spreading greyish or brownish hairs. Leaf-blades oblanceolate-oblong, elliptic-oblong or obovate-oblong, 4.6–22 cm. long, 1.7–8.3 cm. wide, acuminate at the apex, rounded or cuneate at the base, thin, glabrous above save on the midrib, silky beneath in very young buds, but soon glabrous save for the midrib; lateral nerves 12–16; petioles 4–6 mm. long, pubescent. Flowers solitary or paired, axillary, pendulous; pedicels 5–7 mm. long, brownish hairy; bracteoles several, ovate, up to ± 2 mm. long, 1 mm. wide. Sepals triangular, 3.5–4 mm. long, 2.5–3 mm. wide. Corolla at first green, later waxy yellow, sometimes reddish at base (fide Engl. & Diels); tube urceolate, 5 mm. long, 8 mm. wide, glabrous inside, spreading puberulous outside; lobes spreading, but recurving at the tips, 1.2–2.8 cm. long, 3–5 mm. wide, gradually tapering from base to apex, margins reflexed, sometimes misshapen and curved horizontally, glabrous outside, spreading puberulous inside. Stamens ± 1 mm. long. Ovary ovoid-conic, 2.8 mm. long, 1.5 mm. in diameter. Fruiting pedicels up to 1.5 cm. long; fruit dark green, heavily speckled with white or yellow when quite ripe, fusiform, 6–10 cm. long, 2.4–2.7 cm. wide, narrowed to both ends, with 6 broad moderately raised longitudinal ribs, glabrous, but with minute orange gland dots in the dry state; pericarp thin. Seeds irregularly ellipsoidal, 1.5–1.8 cm. long, 0.9–1 cm. wide, 7–8 mm. thick. Fig. 29, p. 126.
