Species

Characteristics

Small tree or erect shrub (? rarely scandent), (0.5–)1–4 m. tall, with sparse branching; branches slender, at first puberulous to densely pubescent, at length glabrescent and bark peeling from the shoots in strips.. Leaves borne towards the apices of the branches, often not fully developed at flowering stage; blades elliptic to ovate-elliptic, 2–7(–16.5) cm. long, 1.5–2.5(–5.2) cm. wide, shortly acuminate at the apex, cuneate at the base, glabrescent to velvety pubescent on both surfaces but particularly beneath and hairy on the midrib and main nerves; petiole 0.3–1 (–2.5) cm. long, pubescent.. Stipules triangular-ovate, 0.5–1.2 cm. long, long acuminate at the apex, ± joined at the base, yellowish or rusty pubescent, ± persistent.. Flowers scented, sessile, clustered at the apices of the branches; bracts stipule-like, toothed.. Calyx silky pubescent; tube elongate-top-shaped, 2–3 mm.long; limb-tube short, becoming 2 mm. long in fruit; lobes lanceolate, 1–2 cm. long, 2–3.5 mm. wide, acute, glabrous inside.. Corolla opening in the evening, sparsely to very densely silky outside, white; tube 2.5–6.5 cm. long; lobes lanceolate-oblong, 2–3.3(–4.5) cm. long, 0.7–1.1(–1.5) cm. wide, glabrous inside.. Anther-tips just exserted.. Style sparsely to densely pilose, the stigma-lobes 6 mm. long, just to well-exserted for 1 cm.. Young fruit subglobose to oblong, 0.8–1.3 cm. long, 5–9 mm. wide, ridged, hairy.
