Information

Shrub, often climbing, 1–10 m. high and up to at least 20 m. long. Branchlets terete, white– or pale grey–tomentose with stellate hairs; indumentum drying rusty. Leaves opposite or subopposite, petiolate; petiole 5–20 mm. long; lamina variable in shape and size, ovate, triangular, oblong or narrowly oblong, or narrowly obovate, 1·2–3 times as long as wide, 1·8–10(–15) x 1–5(–7) cm., acuminate to obtuse at the apex, gradually or abruptly narrowed at the base and at the same time mostly decurrent into the petiole, sometimes with 1–2 large lobes near the base, furthermore entire, pale grey–stellate–tomentose, glabrescent, and with costa (and often main veins) impressed above, stellate–tomentose to pilose beneath; venation inconspicuous. Stipules none. Inflorescence paniculate, very variable in size, usually lax; 3–25 x 2–25 cm., several times branched. Flowers in rather loose clusters, shortly pedicellate or sessile, sweet–scented or malodorant. Calyx cylindrical or nearly so, 3–5 x 1·2–3 mm., white–stellate–tomentose outside (indumentum usually drying rusty), inside glabrous; tube 4–8 times as long as the lobes; lobes subequal, broadly to very narrowly triangular, 0·5–1 x 0·5–1 mm., acute or obtuse, entire. Corolla white, pale orange, or yellow to whitish with orange or yellow throat, with 7–12 mm. long erect lobes, outside stellate–tomentose, inside hirto–pilose in a 2–3 mm. wide ring which has its lower edge at 1–2 mm. above the base; tube nearly cylindrical, 1·5–2·5 times as long as the calyx, 3·7–6·5 times as long as the lobes, 5·5–9 mm. long, usually slightly widened towards the 1–1·8 mm. wide throat; lobes subcircular to oblong, 1·3 x 1·2–5 mm., broadly rounded, entire, spreading to reflexed. Stamens included; anthers sessile with the apex 0–1 mm. below the corolla mouth, oblong, 2–5 times as long as wide, 0·8–1·2 x 0·2–0·5 mm., deeply cordate at the base, rounded to retuse at the apex, glabrous; cells parallel. Pistil 2·5–5·2 mm. long, stellate–tomentose, often glabrous at the apex of the style; ovary ovoid or narrowly ovoid, often laterally compressed, 1·2 x 0·4 to 1·2 x 0·4–1 mm.; style rather short; stigma clavate to subcapitate, decurrent into the style, 0·8–1·2 mm. long. Each cell with one axile oblong placenta with 1–15 ovules outside. Capsule narrowly ellipsoid, 4·5–6 x 1·2 to 1·8 x 1·2 to 1·5 mm., 1·4–2 times as long as the calyx, acute at the apex, hairy like the ovary but less densely; valves often split at the apex. Seed pale brown, oblong, flat, 2·5–2·8 x 0·5–0·8 x 0·2–0–3 mm., narrowly winged at the edges or sometimes not winged; wings acuminate at both ends, minutely reticulate all over.
