Flora of North America species comparison

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

erect, sparsely hirsute proximally, stellate-hairy distally, hairs often pustulose.

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, lanceolate, slightly falcate, 5(–10) × 1–2.5 mm, ciliate;

petioles of lower leaves 1.5–2.5 times as long as blade, reduced distally to 1/2 blade length, stellate-hairy;

blade 2–8 × 2–8 cm, base cordate to somewhat truncate, those most distal sometimes wide-cuneate, surfaces stellate-hairy, proximal leaf blades cordate-orbiculate, margins crenate to dentate, shallowly lobed, apex rounded, distal leaf blades deeply (3–)5-lobed, lobe margins obtusely dentate or pinnatifid, apex narrowly acute.

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

axillary, flowers solitary or distal flowers in racemes.

(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.

conspicuously jointed distally, 1.4–2 cm, not much longer in fruit;

involucellar bractlets distinct, not adnate to calyx, ovate or ovate-deltate to obovate, narrowed to base, 5–8(–12) × 2.5(–5) mm, shorter than calyx, margins entire, surfaces stellate-hairy or glabrate.

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 9–12(–15) mm, lobes enclosing mericarps, stellate-hairy;

petals usually bright pink, rarely white, 20–35 mm, length 2.5–3 times calyx;

staminal column 9–10 mm, sparsely stellate-hairy;

style 18–20-branched;

stigmas 18–20.
