Woody vine or lax shrub, 1-3 m long/tall; stems glabrous, thin and flexuous; new growth glabrous, with a few dendritic trichomes abaxially. Bark of older stems pale greyish brown, glabrous. Sympodial units plurifoliate. Leaves simple, 2-6.5 cm long, 0.8-3.5 cm wide, elliptic to narrowly elliptic, coriaceous or somewhat fleshy, the upper surfaces glabrous and shiny, occasionally with sparse simple uniseriate trichomes to 0.5 mm long along the midvein and the petiole groove, the lower surfaces sparsely pubescent

dendritic trichomes, the trichomes to 0.5 mm long, confined to tufts in the primary vein axils near the midrib; primary veins 3-4 pairs, in the type completely obscured on the upper surface, the midrib yellowish green; base obtuse to truncate; margins entire, sometimes slightly revolute; apex acute; petiole 0.5-1.5 cm long, sparsely pubescent with simple uniseriate trichomes 0.5-1.5 mm long in the groove adaxially, possibly twining. Inflorescences terminal or lateral on short shoots, 2-5 cm long, branched 2-3+ times, with 7-10 flowers, glabrous of with a few dendritic trichomes at the branching points; peduncles ca. 1 cm long or less; pedicels 1-1.2 cm long, <0.5 mm in diameter at the base, ca. 1.5 mm in diameter at the apex, filiform, erect to nodding, glabrous, articulated at the base and inserted into a short sleeve; pedicel scars spaced 0.5-1 cm apart in clusters of 2 or 3. Buds narrowly ellipsoid, the corolla strongly exserted from from calyx before anthesis. Flowers all perfect, 5-merous. Calyx tube 1-1.5 mmm long, conical, the lobes 0.5-1.5 mm long, triangular and keeled, scarious and transparent, glabrous, but with a

Corolla known only from buds, ca. 2 cm in diameter, violet, stellate, lobed ca. 3/4 of the way to the base, the lobes not known from mature flowers, densely pubescent abaxially with weak, simple uniseriate trichomes on exposed bud surfaces, glabrous adaxially. Filaments with the tube ca. 0.5 mm long, the free portions minute, glabrous; anthers ca. 5 mm long, 1-1.5 mm wide, ellipsoid, sagittate at the base, minutely pubescent within between the sutures. Ovary glabrous; style and stigma not seen. Fruit a globose berry, ca. 1 cm in diameter, purple or violet when ripe, the pericarp thin and somewhat shiny; fruiting pedicels 1.8-2 cm long, ca. 1 mm in diameter the base, slightly expanded at the apex, pendent.
