Shrubs 1-3 m tall. Stems moderately to densely pubescent with eglandular unbranched or dendritically branched hairs and also with short-stalked glands; tips of shoots sometimes densely glandular.
Sympodial units 6- to many-foliate.
Leaves simple, the blades 3.5-18 x 1.5-7.5 cm, 2-3 times as long as wide, chartaceous, elliptic or ovate-elliptic, moderately to densely pubescent adaxially and abaxially with eglandular unbranched or dendritically branched hairs and often also with short-stalked glands; base cuneate to slightly decurrent; margin entire; apex acute to acuminate; petioles 1-4.5 cm, densely pubescent with hairs like those of the stem.
Inflorescences 4-10 (-15) cm, unbranched, forked, or sometimes further branched, with ca. (5-) 10-25 flowers, all flowers perfect, the axes moderately to densely puberulent with eglandular unbranched and/or dendritically branched hairs and often also with dense glands; peduncle 3.5-6.5 cm; rachis 1-5 (-10) cm; pedicels 10-25 mm, 10-35 mm in fruit, spaced ca. 2-10 (-15) mm apart, articulated at base.
Flowers with the calyx radius 3-4 mm, the lobes 1.5-2 x 1.5-2 mm, deltate, often abruptly narrowed into acuminate tips, moderately puberulent with glandular and eglandular hairs. Corollas 2-3 cm in diameter, the radius 11-20 mm, stellate, chartaceous, purple (rarely white), the tube 3-4 mm, the lobes 8-17 x 3-4 mm at base, narrowly triangular, acute at apices, sparsely to densely puberulent abaxially with eglandular unbranched and/or dendritically branched hairs and often also glandular hairs, nearly glabrous adaxially except for some hairs on midrib and near apices of lobes. Anthers 5-8 x 1.5-2 mm, lanceolate, usually connivent, yellow, the pores directed distally. Ovary glabrous; style 7-9 x 0.5 mm, cylindrical, glabrous or sometimes with a few hairs; stigma truncate.
Fruits 1.5-2 cm in diameter, globose, obtuse at apex, orange or red when ripe, glabrous; stone cell aggregates absent.
Seeds 5-6 x 4-5 mm, angled, smooth to rugose.
