Shrub or small tree 0.5-4 m tall. Stems densely glandular- and eglandular puberulent (-pubescent) and often also moderately to densely eglandular-pilose.
Sympodial units 4-foliate.
Leaves simple, unlobed or pinnately (2-) 3-lobed, the blades 2-14.5 x 1-7.5 cm, 1-3 (-4) times as long as wide, the unlobed leaves ovate to elliptic-ovate, the lobed leaves divided 1/2 to 7/8 to midrib, with acute to obtuse sinuses, chartaceous to subcoriaceous, sparsely to densely glandular-puberulent and also sparsely to densely eglandular pubescent-pilose adaxially, more so on veins, moderately to densely pubescent abaxially; base (truncate to) cordate with basal lobes up to 1 (-2) cm long; margin entire or pinnately lobed; apex acuminate; petioles 0.5-8 cm, densely puberulent (-pubescent) and often also sparsely to moderately pubescent-pilose.
Inflorescences 2-9 cm, unbranched or rarely forked, with 5-15 (-20) flowers, all flowers perfect, the axes densely glandular- and eglandular-puberulent and often also sparsely to moderately pubescent-pilose; peduncle 1-4 cm; rachis 1-6 cm; pedicels (10-) 15-25 (-30) mm, 10-25 (-35) mm in fruit, spaced (1-) 2-6 (-9) mm apart, articulated above the base, leaving pedicellar remnants 1-2 mm long.
Buds ellipsoidal, obtuse at apex. Flowers with the calyx radius 2-5 mm, the lobes 1-4 x 1-2 mm, deltate, acute at tips, chartaceous, moderately to densely pubescent-pilose. Corollas 1-3 cm in diameter, the radius 7-22 mm, stellate, chartaceous, purple, the tube 2-3 mm, the lobes (5-) 7-19 x (2-) 3-7 mm, narrowly triangular to lanceolate, acute at apices, sparsely to densely puberulent-pubescent abaxially, glabrous adaxially, the margin tomentose. Anther thecae (5-) 6-7 x 1.5-3 mm, lanceolate, connivent, yellow or purple, the pores directed distally; connective 5-6 x 1-2 mm, narrowly triangular, abaxially shorter than thecae at apex, nearly equal to them at base, absent adaxially, dark purple or dark yellow. Ovary glabrate to sparsely puberulent; style 4-7 x 0.5-1 mm, exserted 1-2 mm beyond stamens, cylindrical, glabrous; stigma truncate.
Fruits 1.5-5 x (0.5-) 1-1.5 cm, ellipsoidal, elongated, acute at apex, the color when ripe unknown, densely glandular-puberulent and densely pilose with eglandular hairs 2-3 mm long; stone cell aggregates present.
