erect, base usually woody.

stipules persistent, linear to narrowly oblong-lanceolate, 3–8 × 2–3 mm;

petioles of proximal leaf blades 3 times as long as blade, reduced to 1/2 blade length distally, mid-stem petioles 2 times as long as blade, hairs simple;

distal blades usually round to reniform, deeply 5–7-lobed, lobes acutely 2-pinnatifid, 2–6 × 5–6 cm, base deeply cordate, margins irregularly toothed, apex rounded, obtuse, or acute, surfaces glabrous or sparsely hairy, hairs simple or stellate.

stipules deciduous, ovate, 4–5 × 2–3 mm, papery, apex acute to obtuse, sparsely stellate-hairy and ciliate;

petiole longer than blade;

blade rounded, shallowly and unequally 5–7(–9)-lobed (lobes obtuse), 5–20 × 5–20 cm, base cordate, margins crenate, apex obtuse to rounded, surfaces densely soft stellate-hairy especially abaxially.

axillary, flowers solitary or in fascicles, often appearing short-racemose or subumbellate terminally, long-stalked.

axillary, flowers in fascicles.

(0.5–)0.8–2.5 cm, to 10–35 cm in fruit, hairs simple;

involucellar bractlets distinct, not adnate to calyx, linear to narrowly oblanceolate or elliptic, 5 × 1–1.5 mm, to 7–8 mm in fruit, length 1/2 calyx, margins entire, surfaces glabrous or sparsely hirsute and long-ciliate.

jointed distally, 0.5–1 cm, not much longer in fruit;

involucellar bractlets connate in proximal 1/3, adnate to calyx, lobes broadly ovate to round, 8 × 5–6 mm, longer than calyx, margins entire, apex acute or obtuse, surfaces stellate-hairy.

calyx reticulate-veined, 6–8 mm, to 15 mm in fruit, outer surface hairy, hairs both simple and stellate;

petals bright pink to pale purple or white, 20–35 mm, length 2.5–3 times calyx;

staminal column 7–8(–10) mm, glabrate;

style 11–15-branched;

stigmas 11–15.

calyx 3–4 mm, not much enlarged in fruit, densely stellate-canescent;

petals rose to lavender with 5 darker veins, dark purple basally, 15–20 mm, length 4–5 times calyx, apex emarginate;

staminal column 8–10 mm, glabrous proximally, stellate-hairy distally;

anthers purplish;

style (6–)8(or 9)-branched;

stigmas (6–)8(or 9).

1.2–1.5 mm.

dark brown, 3 mm.

9–11 mm diam.;

mericarps 11–15, black, 1.5–2 mm, apical face and margins rounded, sides thin and papery, smooth, surfaces densely hirsute at least apically.

8–10 mm diam.;

mericarps (6–)8(or 9), 4–5 mm, margins sharp-angled, apical surface and sides ridged, surfaces glabrous or hairy.
