Perennial herbs, 0.4-1 m high, perhaps occasionally annual or only persisting for a few years. Stems terete or slightly angled, lacking spinose processes; young stems densely to sparsely pubescent with spreading glandular, simple uniseriate trichomes 0.5-1 mm long, the trichomes 4-15 celled, drying translucent; new growth densely glandular pubescent; bark of older stems greenish-brown or pale tan. Sympodial units unifoliate or difoliate, the leaves not geminate. Leaves simple, shallowly toothed, the blades 2.5-10 cm long, 1-4.5 cm wide, ovate to broadly elliptic, widest in the lower half, membranous, concolorous; adaxial and abaxial surfaces evenly glandular-pubescent with simple uniseriate trichomes to 2 mm long, these denser abaxially and along the veins, densely pubescent with minute glandular papillae on both leaf surfaces especially in young leaves; principal veins 4-6 pairs, drying paler than the lamina; base truncate and then abruptly attenuate on to the distal part of the petiole; margins shallowly and irregularly toothed, the teeth ca. 0.5 mm long, rounded at the tips and broadly deltate to semi-circular in outline; apex acuminate, the tip blunt; petiole (0.5) 1-2 cm, only winged from the attenuate leaf base in the distal half to third. Inflorescences internodal, unbranched or forked, subumbelliform with most flowers in the distal portion or spaced ca. 0.5 mm apart, 2-3.5 cm long, with 5-8 flowers, densely and finely glandular-pubescent like the stems and leaves; peduncle 1.8-3 cm long; pedicels 0.7-0.8 cm long at anthesis, ca. 0.5 mm in diameter at the base, ca. 0.7 mm in diameter at the apex, slender and tapering, densely glandular-pubescent with short uniseriate trichomes and glandular papillae, spreading at anthesis, articulated at the base but the articulation point somewhat swollen and leaving a minute stump that is darker in colour than the axis, this especially visible in fruiting material; pedicels scars closely packed in the distal part of the inflorescence to 0.5 mm apart, with the lowermost ca. 1 mm distant from the rest. Buds globose to broadly ellipsoid, the corolla strongly exserted from the calyx tube before anthesis. Flowers 5-merous, cosexual (hermaphroditic). Calyx tube 1-1.5 mm long, conical to broadly conical, the lobes 1-1.5 mm long, ca. 1 mm wide, deltate and spathulate, densely glandular-pubescent like the pedicels with uniseriate trichomes and papillae, the tips rounded. Corolla 0.6-0.9 cm in diameter, white with a darker (green?) central star, stellate, lobed 2/3-3/4 of the way to the base, the lobes 2.5-3.5 mm long, 1.5-3 mm wide, triangular, reflexed to spreading at anthesis, the abaxial surfaces glabrous to sparsely papillate with a few glandular trichomes ca. 0.2 mm long. Stamens equal; filament tube minute; free portion of the filaments 0.5-1 mm long, glabrous or sparsely pubescent with a few weak tangled simple uniseriate trichomes adaxially at the very base; anthers 1.8-2.2 mm long, 0.7-1 mm wide, ellipsoid, bright yellow, smooth, poricidal at the tips, the pores elongating to slits with age. Ovary conical, glabrous; style 3.5-4 mm long, straight, exserted beyond the anther cone, sparsely glandular pubescent with weak tangled trichomes and papillae in the basal half where included in the anther cone; stigma minutely capitate, densely papillate, not markedly different from the style. Fruit a globose berry, 0.7-1 cm in diameter, green when young, maturing shiny black, the pericarp thin, not translucent when dry (drying black), opaque, glabrous; fruiting pedicels 0.9-1.2 mm long, tapering from a base ca. 1 mm in diameter to an apex 1-1.2 mm in diameter, not distinctly woody, spreading and becoming deflexed at fruit maturity, persistent and remaining on inflorescence; fruiting calyx not accrescent, the tube 1-1.5 mm long, the lobes 2-2.5 mm long, spreading and later reflexed, covering the lower ca. 1/4 of the berry, the abaxial surfaces not densely papillate (different from
