Woody vine with trailing stems; stems sparsely pubescent with simple, uniseriate trichomes to 0.5 mm long, composed of 2-3 cells, the stems soon glabrescent; new growth densely pubescent with simple uniseriate trichomes, these whitish cream; bark of older stems pale greenish brown, glabrescent. Sympodial units plurifoliate. Leaves simple, 2.7-7(+) cm long, 1-5 cm wide, narrowly ovate to elliptic, membranous, the upper surface glabrous to sparsely pubescent with simple, uniseriate trichomes on the lamina, more densely pubescent on the veins, the trichomes to 0.5 mm long, the undersurfaces almost glabrous to densely pubescent with simple, uniseriate trichomes to 0.5 mm long, these denser on the veins; primary veins 5-7 pairs, yellowish; base truncate to broadly acute; margins entire; apex acute to acuminate; petioles 1-4 cm long, glabrous or pubescent like the adjacent stem, twining. Inflorescence 7-10 cm long, terminal, many times branched, more or less broadly triangular in outline, with 30-40 flowers; peduncle 3-4 cm long, pubescent like the stems; pedicels 1-1.5 cm long, ca. 0.5 mm in diameter at the base, ca. 1 mm in diameter at the apex, nodding at anthesis, sparsely pubescent like the rest of the inflorescence, articulated near the base, leaving a small peg ca. 1 mm high, on the rhachis; pedicel scars spaced 0.1-0.5 cm apart, clustered near the tips of the inflorescence branches. Buds narrowly ellipsoid, the corolla strongly exserted from the calyx tube. Flowers all perfect, 5-merous. Calyx tube 1.5-2 mm long, conical, appearing striped from the thickened venation, the lobes <0.5 mm, mere undulations on the margin of the tube, occasionally somewhat quadrate when sinus splitting, sparsely and unevenly pubescent with simple, uniseriate trichomes to 0.5 mm. Corolla 1.5-2 cm in diameter, white, stellate to rotate-stellate, lobed 1/2 to 3/4 of the way to the base, the lobes 5-8 mm long, ca. 4 mm wide, planar or slightly cupped at anthesis, densely pubescent-papillate with minute simple trichomes abaxially, glabrous adaxially. Filament tube minute, free portion of the filaments unequal, with 3 filaments 1-1.5 mm long and 2 filaments 1-5-2 mm long, pubescent near the base adaxially with tangled, simple uniseriate trichomes ca. 0.5 mm; anthers 2.5-3 mm long, 1-1.5 mm wide, ellipsoid, poricidal at the tips, the pores lengthening to slits with age. Ovary glabrous; style 7-9

, pubescent with simple uniseriate trichomes 0.5 mm long in the lower half; stigma capitate or somewhat bilobed, the surface densely papillate. Fruit a globose berry to 1.5 cm in diameter, green (immature?), the pericarp thin, matte; fruiting pedicels 1.5-1.7 cm long, ca. 1.5 mm in diameter, woody and pendent. Seeds>50 per berry, ca. 2.5 mm long, ca. 2 mm wide, flattened reniform, golden brown, the testal surface minutely pitted. Chromosome number: not known.
