Shrub or small tree 4–15 m. tall, the branches concentrated towards the apex of the main stem; youngest parts of shoots hairy, very soon glabrous or in Zaire material persistently pubescent.. Leaf-blades narrowly oblong or obovate-oblong, 15–40 cm. long, 3.7–12 cm. wide, acuminate at the apex, cuneate to shallowly emarginate at the base, sometimes bullate, at first shortly pubescent above and beneath particularly on the venation, at length practically glabrous save for a few hairs on the midnerve particularly above or in Zaire material often scabrid yellowish pubescent to densely velvety all over; lateral nerves ± 15–30 on each side; petioles 0.4–1.3 cm. long; stipules ovate-triangular, 1.1–2.3 cm. long, 0.9–1.9 cm. wide, glabrous to pubescent outside, deciduous, the scar hairy within.. Inflorescences axillary, often trichotomous from the extreme base, peduncles or apparent peduncles 0.5–2.5 cm. long, the bracts borne towards the apex, 2–6 mm. long, 1–1.5 mm. wide; secondary peduncles 5 mm. long; pedicels 1–5 mm. long; all parts of inflorescence rather sparsely to very densely yellowish pubescent.. Calyx hemispherical, the tube 1–1.5 mm. long, the limb 1.1–1.6 mm. long, glabrous or pubescent at the base, the lobes no more than slight undulations on the limb edge.. Buds grooved and ribbed when dry.. Corolla glabrous outside, whitish or pale green with blue hairs in the throat; tube 1.6–3.2 mm. long; lobes ovate-triangular, 2.2–3 mm. long, 1.3–1.7 mm. wide.. Stamens almost as long as the lobes in short-styled flowers, just exserted in long-styled flowers.. Disc subglobose, pubescent to tomentose, the central stigma-pit surrounded by 10 small pits visible only when hairs have worn off.. Style densely hairy, 0.8–1.7 mm. long in short-styled flowers, 2–6 mm. long in long-styled flowers; stigma 0.7–1.25 mm. long.. Berries green, subglobose, ± 6 mm. in diameter..
