erect, base usually woody.

erect to ascending, sparsely hirsute proximally, stellate-hairy distally.

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.

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.

axillary, flowers in fascicles.

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

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.

(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.

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;
