Characteristics

Forest shrub or small tree, apparently sometimes somewhat scandent, 1.5–9(–12) m. tall, with finely adpressed pubescent to distinctly hairy twigs, older stems glabrescent.. Leaf-blades oblong-elliptic to oblong-lanceolate or-oblanceolate, 3.5–15.5 cm. long, 0.9–5.2 cm. wide, acuminate at the apex, cuneate at the base, glabrous above save for short hairs on the narrowly impressed midnerve, entirely glabrous or pilose on the main nerves beneath; lateral nerves ± 12 on each side, together with other venation prominent to very prominent beneath; petioles short, 2.5–10 mm. long, usually pubescent; stipules lanceolate, 0.3–1.35 cm. long, 0.8–2.5 mm. wide, adpressed pubescent.. Inflorescences axillary, short, the cymes ± 1 cm. long; peduncles 1–5 mm. long; pedicels 0–3.5(–4) mm.; bracts lanceolate, 1.5–2.5 mm. long; all parts pubescent.. Calyx glabrous, pubescent or hairy; tube 0.6–1.1 mm. long; limb-tube 0.3–0.9 mm. long; lobes yellow, red or purple, lanceolate-subulate, 0.4–2.8 mm. long.. Corolla glabrous (or rarely puberulous) outside, greenish, yellow, cream or white but sometimes reported to be orange or yellow turning red and certainly often drying red; tube 2–5 mm. long, longest in short-styled flowers; lobes oblong-lanceolate, 1.7–3.1 mm. long, 0.8–1 mm. wide.. Stamens as long as the corolla-lobes in short-styled flowers, just included in long-styled flowers.. Disc depressed, glabrous.. Style glabrous or sparsely papillate, 3–4.6(–5.5) mm. long in long-styled flowers, 1.4–2.8 mm. long in short-styled flowers; stigma 0.45–0.8 mm. long.. Berries orange, red or tinged purple, subglobose, 3–5 mm. long, 2.5–4 mm. across.. Seeds orange-brown, ellipsoid, 0.8 mm. long, 0.5 mm. wide, very strongly pitted.
