Characteristics

A small shrub 0.9–2 m. tall or sometimes scrambling to about 8 m.; young branchlets with rather coarse ferruginous hairs but glabrous when older, ridged, purplish-grey, lenticellate.. Leaf-blades elliptic to oblong or obovate, 2.7–10.5(–12) cm. long, (2–)3–5(–7) cm. wide, obtuse, rounded or slightly emarginate at the apex, rounded or cordate at the base, coriaceous, mostly bluish-or greyish-green and glabrous above save for a few hairs on the impressed midrib, finely pubescent beneath with small stellate hairs and also some larger ferruginous stellate hairs when young, but almost or quiteglabrous when old; main nerves mostly impressed above and slightly-prominent beneath, but often flat and with the venation mostly obscure; petiole 2–5 mm. long, channelled, stellate-pubescent.. Flowers rather large, up to 7.5 cm. in diameter, terminal or leaf-opposed, solitary; pedicels 0–3 mm. long, tomentose with pale brown or ferruginous stellate hairs; bracteoles lanceolate, 5–7 mm. long, 2–4; mm. wide, tomentose.. Sepals ovate, 6–7 mm. long, 6.5 mm. wide, obtuse or acute, united at the base for up to a third of their length, entirely covering the petals in bud, tomentose on both surfaces with pale brown or ferruginous stellate hairs.. Petals cream or straw-coloured, tinged green at the base or all green, obovate-orbicular to narrowly elliptic-rhomboid, the inner sometimes rather narrower, (1.5–) 3–4.5 cm. long, 0.9–3.3 cm. wide, obtuse, rounded or slightly acute, thin, finely tomentose with stellate hairs outside, mostly glabrescent inside save at apex.. Stamens 1–2 mm. long, the prolongation of the connective thick, truncate or rounded.. Carpels 10–20, tomentose, 10–12-ovuled.. Fruiting pedicels 4–8 mm. long; monocarps 5–11, oblong-cylindrical, (1–)1.7–2.5 cm. long, 0.8–1.1 cm. wide, (3–)5–8-seeded, slightly constricted between the seeds, sometimes apiculate, densely tomentose with yellowish-fawn or grey stellate hairs, rugose or somewhat verrucose; stipes 4–8 mm. long.. Seeds shining brown, variously shaped, mostly slightly curved, with traces of 3 angles or compressed, 7–10 mm. long, 4–5 mm. wide, 2.5–3.5 mm. thick, shortly divided into connivent lobes at the hilar end..

Leaves petiolate; lamina 4.7–10.7 (12) x (2.5) 3–5 (6) cm., elliptic to oblong or obovate, obtuse to rounded or slightly emarginate at the apex, not or scarcely acuminate, rounded or cordate at the base, coriaceous, bluish-or greyish-green and glabrous except sometimes along the midrib above, brighter green and sparsely pubescent with simple and stellate hairs or sometimes glabrous below, with nerves slightly prominent below and slightly impressed above or both surfaces plane; petiole 2–4 mm. long, sparsely pilose, usually transversely ribbed.
A shrub or scrambler. It can grow 8 m high. The leaves are broadly oval. The base is heart shaped or rounded. They are 3-12 cm long by 3-5 cm wide. The flowers are cream or pale yellow. They occur singly. They are large. The plant flowers then dies. The fruit are 17-25 mm long by 8-11 mm wide. There are 5-8 seeds.
Fruit on a pedicel 4–8 mm. long; ripe carpels c. 5–10, (1) 1.7–2.2 x 0.8–1.1 cm., several-seeded, cylindric, sometimes apiculate, slightly constricted between the seeds when ripe and dried, yellowish-fawn or grey, tomentellous, rugose or verrucose, with stipes 6–8 mm. long.
Petals cream to white or pale green, thin, not fleshy, equal, 15–40 mm. long, obovate-orbicular or rhomboid, sometimes slightly unguiculate, obtuse or rounded, glabrous above, sparsely tomentellous below.
Sepals 6–7 mm. long, united only in the lower third, covering the petals in bud and separating at anthesis, ovate, acute or obtuse, fawn-or greyish-tomentellous on both surfaces.
Flowers terminal, solitary; pedicels absent or up to 3 mm. long, rusty-pilose; bracteoles lanceolate.
Stamens 1–2 mm. long, linear, cream; connective-prolongation thick, truncate or rounded, pubescent.
Shrub 1–2 m. high, sometimes scrambling or climbing, when it may reach 7–8 m.
