Scrambling herbs or shrubs to 2 m tall, armed or unarmed. Stems erect or spreading, terete, prickly and stellate-pubescent; prickles, if present, to 3 mm long, 1.5-2 mm wide at the base, slightly curved, pale yellowish tan; pubescence of sessile to very short-stalked porrect-stellate trichomes, the stalks, if present, to 0.2 mm, the rays 4-6, ca. 0.5 mm long, the midpoints 2-4 celled, to 2 mm long, glandular tipped, drying with violet tinge at cell junctions (trichomes described as black to reddish

); new growth densely stellate-pubescent, the trichomes tangled, soon deciduous and the stems glabrate; bark of older stems ashy white. Sympodial units difoliate, the leaves not geminate. Leaves simple, shallowly lobed, the blades 2-9 cm long, 1.7-6.8 cm wide, 1-1.3 times longer than wide, ovate to broadly triangular, widest in the lower third, chartaceous, somewhat discolorous, unarmed or very occasionally sparsely armed along the midrib and major veins with small prickles; adaxial surface evenly and densely pubescent with sessile and very short-stalked porrect-stellate trichomes, the rays 4-8, to 0.5 mm long, glandular at the tips, the midpoints 2-4-celled, to 2 mm long, glandular at the tips; abaxial surface with similar porrect-stellate trichomes, but these denser especially along the veins; major veins 3-4 pairs, densely pubescent; base abruptly truncate to cordate, somewhat oblique; margins shallowly lobed, the lobes 3-4 on each side, to 0.5 cm long, broadly deltate, apically rounded, the sinuses less than halfway to the midrib; apex acute to obtuse; petioles 1-4 cm long, ca. half as long as the leaf blades, unarmed or with a few prickles, densely stellate pubescent like the stems. Inflorescences 0.3-1 cm long, internodal and lateral, unbranched, with 1-3 flowers, only 1 or 2 flowers open at any one time, pubescent with mixed sessile and short-stalked stellate-porrect trichomes like those of the stems, with multicellular midpoints to 2 mm long, unarmed; peduncle absent to 0.2 cm long; pedicels 2.5-4 cm long, ca. 0.7 mm in diameter at the base, ca. 0.7 mm in diameter at the apex, spreading and slightly nodding at anthesis, unarmed or with a few prickles, more sparsely stellate-pubescent than the inflorescence axes, articulated at the base; pedicel scars tightly spaced ca. 1 mm apart. Buds elongate and tapering, curved, strongly exserted from the calyx before anthesis. Flowers 5-merous, heterostylous and the plants andromonoecious, with the distal flower(s) short-styled and smaller than the hermaphroditic flowers. Calyx with the tube 3.5-4 mm long, conical, sparsely prickly, the lobes 6-8 mm long, ca. 1 mm wide, long-triangular to lanceolate, unarmed, densely stellate-pubescent with mixed sessile and short-stalked porrect-stellate trichomes with multicellular glandular midpoints like those of the pedicels, the pubescence denser than that of the pedicels. Corolla (2-)3.5-5 cm in diameter, violet or deep purple, rotate-stellate, lobed to 1/3 of the way to the base, abundant interpetalar tissue present, the lobes (10-)14-17 mm long, (11-)14-18 mm wide, broad-deltate, spreading or somewhat campanulate at anthesis, mostly glabrous adaxially but with a few stellate trichomes along the petal midvein, densely stellate-pubescent abaxially with densely tangled sessile trichomes where exposed in bud, these densest at the tips, the interpetalar tissue glabrous. Stamens markedly unequal; anthers 3 long and 2 short, the long anthers 12-15 mm long, ca. 2 mm wide, strongly curved and tapering, the short anthers ca. 10 mm long, 0.6-0.7 mm wide, straight or slightly curved, all anthers yellow, glabrous, poricidal at the tips, the pores directed distally, not elongating to slits with drying; filament tube minute, glabrous; free portion of the filaments 1-1.5 mm long, glabrous. Ovary conical, glabrous; style ca. 5 mm long in short-styled flowers, 12-15 mm long, in long-styled flowers, strongly curved, glabrous; stigma capitate, the surfaces minutely papillose. Fruit a globose berry, 1-2 per infructescence, 1.1-1.5 cm in diameter, completely enclosed in the accrescent calyx, yellowish brown when ripe, drying and breaking into 4 irregular valves when ripe, the pericarp thin and shiny, glabrous; fruiting pedicels 3-3.5 cm long, 1-1.5 mm in diameter at the base, 3-4.5 mm in diameter at the apex, unarmed, somewhat woody, sharply deflexed and pendent; fruiting calyx strongly accrescent, the lobes often breaking off. Seeds 20-30 per berry, 4-5 mm long, 3-3.5 mm wide, flattened reniform, pale tan or yellowish brown, the surfaces minutely pitted, the testal cells with straight walls, pentagonal in outline, the margins incrassate. Chromosome number: not known.
