Shrubs ca. 1-2 (-5) m tall. Stems glabrous to densely pubescent with unbranched or dendritically branched hairs, the branched hairs often long-stalked and with three or more terminal rays.
Sympodial units 4-many-foliate.
Leaves simple, the blades 3-12.5 x 0.5-3.5 cm, ca. 2-10 or more times as long as wide, elliptic-ovate to narrowly elliptic or lanceolate, chartaceous to subcoriaceous, glabrous to moderately pubescent adaxially, glabrous to densely pubescent abaxially with simple or branched hairs, the hairs denser on margins and veins; apex acute to acuminate; margin entire; base cuneate to decurrent and occasionally subhastate with 1-2 small lobes; petioles 0.3-2.5 cm, sparsely to densely pubescent.
Inflorescences 0.5-5 cm, unbranched or forked, with 1-15-flowers, the axes glabrous to densely pubescent with unbranched, forked, or dendritically branched hairs and sometimes also with small stalked glands; peduncle 0.5-3.5 cm; rachis up to 3 cm; pedicels 5-15 (-20) mm, nearly contiguous or spaced ca. 1-15 mm apart, articulated at the base.
Flowers with the calyx radius 2-9 mm, the lobes 1-6 x 1-2 mm, deltate to narrowly triangular and often abruptly narrowed distally, acute to acuminate at tips, sparsely to densely pubescent. Corollas 1.5-2 cm in diameter, the radius 8-13 mm, stellate, chartaceous, purple or white with a lighter or darker star at base, the tube 2-3 mm, the lobes 5-10 x 2-4 mm at base, triangular to narrowly triangular, acute at apices, sparsely to densely puberulent abaxially with unbranched or branched hairs, nearly glabrous adaxially except for a few hairs on midveins. Anthers 4-6 x 1.5-2 mm, lanceolate to narrowly oblong, usually connivent, yellow, the pores directed distally and adaxially. Ovary glabrous; style 5-6 x ca. 0.5 mm, cylindrical, glabrous to moderately puberulent; stigma truncate to subcapitate.
Fruits 1.5-2.5 x 0.8-2 cm, globose, ellipsiodal, or ovoid-fusiform, obtuse or acute at apex, the color unknown, glabrous; stone cell aggregates absent.
Seeds 2-2.5 x 2 mm, lenticular, puberulent on margin but otherwise nearly glabrous.
