Stems moderately armed with recurved, yellow to green roselike prickles, these 3-8 mm in length, the base 2-4 x 0.5-2 mm, moderately to densely pubescent with white, porrect-stellate hairs, the stalks nearly absent to 1 mm, multiseriate, the rays 6-8, 0.5-1mm, unicellular to multicellular, the midpoints absent to 1 mm.
Sympodial units difoliate, the leaves geminate, those of a pair unequal.
Leaves simple, the blades 6-13x3-8 cm, rhombic, unlobed to 2-5 lobes per side, the sinuses cut less than 1/6 of the way to the midvein, the lobes obtuse, leaves chartaceous, slightly discolorous, dark green adaxially, light green abaxially, with both leaf surfaces sparsely to moderately pubescent with stellate hairs like those of the stem; major veins 3-6 on either side of the midvein, the midrib abaxially unarmed or with occasional prickles like those of the stem; base acute, decurrent onto petiole; apex acute to obtuse; petioles absent to 1 cm, moderately pubescent with hairs like those of the stem, unarmed or occasionally armed with prickles like those of the stem.
Inflorescences 1-3 cm, extra-axillary, unbranched, with 5-15 flowers, apparently all perfect, the axes moderately to densely pubescent with hairs like those of the stem but with the stalks to 1.5 mm, unarmed; peduncle absent to 0.5 cm; rachis 1-3 cm; pedicels 5-10 mm in flower, 10-15 mm in fruit, filiform, nearly contiguous, spaced 0.5-1.5 mm apart.
Flowers apparently all perfect, 5-merous. Calyx 2-7 mm long, the tube 1-2 mm, the lobes 3-5 x 0.5-1.5 mm, very narrowly triangular, moderately to densely pubescent with hairs like those of the stem but with the stalks to 1.5 mm, unarmed; fruiting calyx 4-9 mm, the lobes not accrescent in fruit. Corolla 1-2 cm in diameter, chartaceous, white to yellow-white, stellate, lobed nearly to the base, the lobes 4-6 x 1.5-3 mm, narrowly triangular, sparsely pubescent abaxially with hairs like those of the stem with midpoints either absent or to 1 mm, midpoints either white or occasionally purple, glabrous adaxially. Stamens 4-6 mm; filaments up to 1 mm, glabrous; anthers 3.5-5 x 1-2 mm, attenuate, tapering, connivent, yellow, the base cordate, the apex obtuse, the pores apical, directed introsely. Ovary very sparsely pubescent with multicellular, uniseriate glandular hairs 0.2-0.4 mm long; style 4-6 x 0.5-1.5 mm, exserted beyond stamens, cylindrical, white, sparsely pubescent with stellate hairs like those of the stem; stigma up to 1 mm wide, cylindrical, green.
Fruit a thin-skinned berry, 4-12 mm in diameter, globose, mottled green when immature, mottled orange or red when mature, glabrous.
Seeds 40-70 per fruit, 1-1.5 x 0.5-1 mm, reniform, brown, flattened, the surface netlike with many pits created by small raised ridges.

      Erect or straggling shrub to 3 m tall; stems very densely tomentose, the pubescence with an ochraceous cast, of variously stalked, often dendritic, sub- echinoid stellae with long and torulose radii, and also of scattered hairs bearing one very long arm, armed with short (5 mm long), stout-based recurved spines. Leaves thick, 4-15 cm long, ovate, rhombic or obovate, often almost as broad as long, typically acute apically, basally long-acuminate, encompassing the petiole almost to the base, the leaves thus subsessile, the margins entire or usually shallowly angular-sinuate, both surfaces with dispersed, stalked pauciradiate non-porrect stellae. Inflorescence lateral, a short raceme, sometimes subumbellate; peduncle short with long-stalked and hydroid bristles, some of these dendritic; pedicels 2 cm long, slender, villous. Flowers very small; calyx 4 mm long, lobed about 1/2 the way down, the lobes narrowly lanceolate to subulate and bearing prominent dendritic-hydroid bristles; corolla white, 8-11 mm across, lobed '/2 the way down; stamens equal, the filaments very short (0.2 mm long), glabrous, the anthers 3-4 mm long, elongate-attenuate, opening by relatively large terminal pores and sometimes ultimately by longitudinal slits; style sometimes pubescent. Fruit a juicy, red, shiny berry 5 mm across; seeds 1.5-2 mm across, lenticular, orange, foveate.
