Shrub, sometimes scandent, up to 6 m tall; young branches shortly, sometimes sparsely, stellate-pubescent.. Leaves elliptic to ovate, 2.2–14 cm long, 1.3–7 cm wide, acute to acuminate at the apex, rounded to cuneate at the base, margins serrate, ± glabrous with a few scattered stellate hairs above, a thin covering of minute stellate hairs beneath; petiole 2–4 mm long, shortly stellate-pubescent; stipules subulate, up to 6 mm long.. Inflorescences terminal or subterminal leaf-opposed axillary 3–9-flowered cymes, axes covered with a short greyish green stellate pubescence; peduncle 5–17 mm long; pedicels up to 22 mm long.. Flowers white; sepals 15–23 mm long, white inside, green outside, the margins thickened and appearing whitish in bud; petals broadly ovate, 6–11 mm long, 4–7 mm wide, white, green at the base.. Androgynophore glabrous for 1–2 mm at the base, produced and pubescent for 2–4 mm above the node.. Stamens 9–14 mm long; filaments white;ovary ± 2 mm long, densely hairy.. Style 10–12 mm long, white; stigma green.. Fruit (1–)4-lobed, 14–20 mm wide, the lobes 9–14 mm long, 7–10 mm wide, covered in long hairs with a small wart at their base, becoming glabrous, green with white dots maturing reddish brown..

More
A shrub which tends to scramble. It has many stems. It can be a small tree 6 m high. The bark is grey-brow. The branches often droop. The leaves are oblong to sword shaped. They are 6-19 cm long by 2.5-9 cm wide. They are bright green on both surfaces. The edges of the leaf are toothed or scalloped. The leaf stalk is 8 mm long and hairy. They flowers are white. They are 3-4 cm across. They occur in groups of 3-9 opposite the leaves. The sepals curve backwards except for the tip. The petals are frilled and crinkled. The fruit have 4 lobes. Each lobe is 10 mm across. They are shiny orange-red when mature.
Leaf-lamina 6–19 × 2·5–9 cm., oblong-lanceolate, subrhombic or narrowly obovate, acute or shortly acuminate at the apex, margin finely crenate-dentate, rounded or subcuneate at the base, finely pubescent above when young but soon glabrous, finely but more densely pubescent below and also eventually glabrous; petiole up to 0·8 cm. long, pubescent; stipules up to 1·4 cm. long, lanceolate-acuminate, with a dorsal keel, pubescent.
Petals white, up to 15 × 10 mm., ovate-lanceolate; lamina much wider than the nectariferous claw which is circumvillous and ledged above on the inside and up to 1·5 mm. long.
Inflorescences opposite the leaves, 3–9-flowered; peduncles up to 2 mm. long, pubescent; pedicels up to 15 mm. long, pubescent; bracts c. 2 mm. long, shortly triangular.
Sepals 1·5–2·2 × 0·35–0·5 cm., linear-oblong, hooded but not thickened at the apex, greenish-pubescent outside, white and glabrous inside.
Ovary 4-lobed, pubescent; style up to 10 mm. long, finely stellate-pubescent or glabrous except at the base; stigma-lobes broad.
Androgynophore with a lower glabrous portion up to 1·5 mm. long and an elongated pubescent upper portion up to 4·5 mm. long.
Shrub, sometimes scandent, up to 5 m. tall; branchlets rather pale or reddish-pubescent, soon becoming glabrous.
Fruit orange-red when ripe, c. 2 cm. in diam., 4-lobed, shining, glabrescent.
