Characteristics

Herb 0.2–1.0 m high. Branchlet with stellate hairs (fine 0.2–0.8 mm long, coarse 0.4–0.7 mm long), with sparse coarse bristles (0.3–0.6 mm long), and sparse fine bristles (0.2–0.5 mm long). Stipules ± persistent, 4–5 mm long. Mid-stem and distal leaves: 3-lobed (rarely unlobed, or 5-or 7-lobed), lobing not extended to apex of petiole, the primary lobes scarcely lobed, palmately veined. Mid-stem leaves: petiole 10–30 mm long with indumentum similar to that of the branchlet; lamina ovate or broadly ovate, 20–65 mm long, 15–45 mm wide, margin strongly serrate, lobe apex acute or obtuse, with fine and coarse stellate hairs; foliar nectary absent. Flowers solitary in leaf axils, chasmogamous, pedunculate; peduncle 10–20 mm long, with fine and coarse stellate hairs, rarely also with fine bristles; pedicel 4–10 mm long, indumentum dissimilar to that of peduncle (stellate hairs longer and denser, coarse bristles present); epicalyx 12–14-segmented, segments linear, free at the base, 10–13.5 mm long, shorter than the calyx to equally as long as the calyx; calyx at anthesis 13–15 mm long, distinctly accrescent in fruit, with stellate hairs, fine and coarse bristles and sparse glandular hairs, without prominent marginal ribs, lobes triangular, acute at the apex; calyx nectary absent; petal 19–26 mm long, yellow distally faintly flushed pink, base sometimes with fine pale red striations; staminal column 7–10 mm long with the stamens distributed along the distal 4–7 mm of the column, staminal filaments 1–2.3 mm long, anthers yellow, pollen yellow; style (including style branches) exserted 2.3–3.8 mm beyond the apex of the staminal column, branches 5, 2.3–3 mm long, stigmas capitate, 0.8–1.2 mm across, stigmatic hairs 0.1–0.2 mm long, ovary hairy.
