Characteristics

Shrub 0.5–3.5 m high. Branchlets with stellate hairs (fine and coarse), aculei (0.5–1.75 mm long) and glandular hairs. Stipules linear to subulate, 4–5 mm long, caducous. Climax leaves: petiole 25–45 mm long, indumentum dissimilar to that of branchlet with denser hairs and aculei absent; lamina broadly ovate to depressed ovate, unlobed to shallowly 3 (–5)-lobed (lobes shorter than wide, with acute, obtuse, rounded or acuminate apex), 50–80 (–135) mm long, 65–100 (–160) mm wide, truncate to cordate base, serrate or entire margin, concolorous to weakly discolorous, the indumentum denser on the abaxial surface, the midrib and primary vein indumentum similar to that of the interveinal regions, with stellate hairs and glandular hairs, the stellate hairs scattered to very dense (on midstem leaves the epidermis is always visible, on distal leaves it is often obscured), fine to coarse (fine hairs 0.05–0.15 mm long, coarse hairs 0.15–0.35 mm long). Foliar nectary at lamina base, 3–8 mm long. Distal leaves narrowly ovate or narrowly elliptic. Flowers solitary in leaf axils/sympodial in few-to several-flowered terminal and/or distal-axillary racemoid axes, not pedunculate; pedicel 9–15 mm long, with stellate hairs and aculei; epicalyx with stellate hairs and acule, 9–11-segmented, the segments free at the base, linear, incurved, as long as the calyx, 17–23 mm long, 1-veined; calyx at anthesis 7–13 mm long (17–24 mm long in fruit), the indumentum yellowish with moderately dense stellate hairs and aculei; calyx nectaries absent; petals 50–60 mm long, pink, the proximal region reddish; staminal column c. 17 mm long, filaments c. 2 mm long; the style exserted c. 3 mm beyond the apex of the staminal column, branches c. 2 mm long, stigmas capitate, hairs c. 0.1 mm long. Capsule ovoid, 15–17 mm long, densely hairy, the hairs appressed, with stellate hairs also present; beak c. 1 mm long. Seeds angular-reniform, c. 4 mm long, striate.
