Characteristics

A scrambling shrub, 3–5 m. tall.. Flowering branches reddish, fulvous-pilose and sometimes thickly so above, glabrescent and pruinose (? always) below; prickles numerous, ± stout, hooked, glabrous, up to 5 mm. long.. Leaves imparipinnate (2–3-jugate) or the upper ones trifoliolate; terminal leaflets broadly ovate, up to 6.5 × 3.6 cm., the lateral ones rather smaller and narrower, ovate to ovate-lanceolate, 4.5–6 × 2.3–3.2 cm.; all acute or acuminate, basally rounded, sharply and irregularly serrate, the nerves often markedly excurrent, green on both surfaces but paler below, glabrous or with pubescent midrib and nerves on either or both surfaces and sometimes with scattered, ± appressed hairs on the lamina above; lateral nerves straight or arcuate.. Inflorescence usually a rather restricted, largely or wholly leafless, cylindrical panicle, but sometimes more diffuse, commonly up to 17 × 5 cm., the peduncles and pedicels usually spreading at an angle of 90° or a little deflexed; flowers solitary or in pairs; the branchlets, peduncles (if present) and pedicels grey-green-tomentose and usually very aculeolate.. Calyx tomentose, often purplish on the outside, becoming marginally greener, 9–10(–15) mm. long, deeply divided into oblong-lanceolate or lanceolate caudate-acuminate lobes 7–8 mm. long, which spread or reflex after maturity.. Petals white, “turning magenta,” obovate or obovate-elliptic, 6.5–8 × (4–) 6–6.5 mm., notched or entire.. Fruit tomentose, often densely so, orange-red or black (? when mature), edible.
More
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.
