Shrub 0.5–2 m high. Branchlets with very dense coarse bristles (3–4.5 mm long), indumentum yellowish. Stipules more or less persistent, linear to very narrowly triangular, 15–25 mm long, 0.3–1 mm wide, indumentum like branchlets. Mature leaves: petiole 20–75 mm long, indumentum like branchlet; lamina broadly ovate to orbicular, unlobed or shallowly 3-lobed (the lobes shorter than wide), 20–75 mm long, 28–110 mm wide, cordate to truncate base, serrate, serrulate or dentate margin, rounded apex, concolourous, indumentum generally similar on both surfaces, similar on veins and interveinal regions, abaxial surface with stellate hairs (scattered to moderately dense) and coarse bristles (sparse), adaxial surface with stellate hairs (sparse, mostly 1 or 2 armed (to 3-armed), rays 2–4 mm in diam.), indumentum whitish to yellowish; distal leaves reduced in size but not shape. Flowers solitary in leaf axils; not obviously pedunculate; pedicel 5–13 mm long, with stellate hairs, pedicel marginally wider distally. Epicalyx segments 9, subulate, 15–19 mm long, shorter than the calyx at anthesis, free at the base, straight, sometimes becoming recurved at the apex in fruit, with sparse stellate hairs and coarse bristles. Calyx 21–29 mm long at anthesis, enlarging to 30 mm long in fruit; lobes ovate, the apex acuminate 16–20 mm long at anthesis, enlarging to 19 mm long in fruit, abaxial indumentum with sparse, simple, appressed hairs on apical half of lobe, remainder of lobe and basally glabrous, hairs whitish to brownish. Petals 48–58 mm long, adnate to staminal column at base but otherwise free, purple or mauve, with a red basal spot, with sparse to moderately dense, stellate hairs abaxially, basally and along one side only of each petal, adaxially glabrous. Staminal column 14–16 mm long, apex irregularly 5-lobed, with the stamens usually distributed along the full length of the column; staminal filaments 1–3 mm long, anthers yellow, pollen yellow. Style 5-branched, with branches 4–5 mm long, exerted 5–10 mm beyond the apex of the staminal column, stigmas capitate, 1–1.2 mm wide, hairy, hairs 0.5–0.6 mm long, ovary glabrous. Capsule ovoid, 12–15 mm long, glabrous, capsule beak 1.5–2 mm long. Seeds subreniform, 2.7–3 mm long, with an indumentum of long silky pubescent hairs, hairs whitish, 2.5–3 mm long, the hairs sometimes twisting together in clumps, flat sides of seed with shorter appressed hairs.
