A scrambling shrub. The flowering branches have prickles. The leaves are 7-18 cm long by 4-16 cm wide with 2-3 leaflets. The leaflets have shallow, irregular teeth. The flowering shoots are in the axils of leaves or at the ends of branches and are 11-28 cm long by 3-7 cm wide with a few to many flowers. The fruit are hairy and 1 cm long. They are red to black.
Leaves 7–18 x 4–16 cm., 2–3-jugate or the uppermost ternate, thin, not leathery; petiole and rhachis pubescent and aculeate like the stems or sometimes glabrous except for a densely fulvous-villous line along the adaxial surface; distal leaflets sessile; proximal ones with petiolules c. 2 mm. long; terminal leaflet with petiolule 0·5–2(4) cm. long.
Leaflets ovate-acute to oblong-acuminate, with shallowly, rather irregularly serrated margin; superior surface dark green, glabrous to sparsely appressed-pilose; inferior surface paler green with pilose veins and glabrous lamina, the midrib prickly, prickles very occasionally appearing also on lateral veins.
Inflorescences few-flowered to many-flowered, axillary and terminal, 11–28 x 3–7 cm., exceeding leafy part of shoot; peduncles and pedicels with indumentum like stems, almost without prickles to very prickly; pedicels and calyx sometimes with sparse long-stipitate glands.
Flowering branches glaucous-pubescent, sometimes glabrescent, often whitish-pruinose below, moderately prickly; prickles 1–3·5 mm. long, almost straight or decurved.
Calyx densely greyish-tomentose, deeply divided into ovate to triangular lobes, acute, acuminate to long-cuspidate, 6–9 mm. long, spreading in fruit.
Petals white, pale pink to purple or pale yellow, slightly exceeding to 2 x length of sepals, with suborbicular limb and narrow claw.
Fruits globose, c. 0·8–1·0 cm. long, black and edible when ripe; carpels few, pubescent.
Straggling scrambling shrub.
Stipules filiform to linear.
