Scandent shrub, up to 10 m. tall; bark brown, stripping; young parts densely floccose, glabrescent.. Leaves petiolate; petiole 0.5–2.0 cm. long; lamina narrowly ovate to almost lanceolate or more rarely (and not in our area) hastate, 8–11(–15) cm. long, 3–5(–7) cm. wide, narrowing above to an acute or acuminate and minutely apiculate apex, rounded below to a cuneate-acuminate base; margin entire, very shallowly undulate or very widely and bluntly dentate.. Inflorescence a pyramidal compound raceme of clusters of cymules; lateral racemes up to 7 cm. long and 3.5 cm. in diameter; pedicels 1 mm. long.. Corolla cream-coloured or yellow, orange in the throat; tube brownish-cream; corolla-lobes square, with truncate apex.. Anthers subsessile, inserted just within the throat.. Ovary ovoid, hirsute.. Fig. 6/7, p. 37.
Shrub, often scandent, 0.8-3.0(-7.0) m high, lateral branches patent, subterete. Stipules absent, soon deciduous, represented by faint interpetiolar ridge. Bracts linear-terete. Leaves opposite or subopposite; upper surface green, lower surface tawny and rufous, stellate-tomentose; blade ovate-lanceolate to ovate-oblong, varying in size, base cuneate, apex acuminate to acute; petiole bases prominently concave, winged in upper half by decurrent blade. Inflorescences axillary, paniculate. Flowers: corolla cream-coloured, light orange to whitish and orange throat. Fruit small capsule, narrowly ovoid. Flowering time July, Aug.
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.
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.
Shrub, 1.0-2.7 m, sometimes up to 7 m high. Leaves distinctly petioled, base cuneate and decurrent on petiole. Stipules absent or a faint interpetiolar ridge, persisting petiole bases prominent, concave. Corolla tube long, cylindrical. Stamens included. Flowers cream, light orange to whitish with orange centre.
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.
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.
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.
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.
Inflorescence paniculate, very variable in size, usually lax; 3–25 x 2–25 cm., several times branched.
Branchlets terete, white– or pale grey–tomentose with stellate hairs; indumentum drying rusty.
Flowers in rather loose clusters, shortly pedicellate or sessile, sweet–scented or malodorant.
Shrub, often climbing, 1–10 m. high and up to at least 20 m. long.
Each cell with one axile oblong placenta with 1–15 ovules outside.
Stipules none.
