Flora of North America species comparison

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

trailing to ascending, hairs usually both simple and stellate.

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 persistent, narrowly to ovate-triangular, 3–5(–6) × 2–3 mm;

petiole on proximal and midstem leaves to 3 times as long as blade, usually 2 times longer on distal leaves, sparsely hairy, hairs simple and stellate;

blade cordate to broadly reniform, unlobed or broadly and very shallowly 5-lobed, 1–5 × 1–5 cm, base cordate, margins finely crenate or dentate, apex rounded, surfaces glabrous or sparsely stellate-hairy.

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

axillary, flowers solitary or in 2–10-flowered fascicles (compact cymes), obviously stalked.

(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.

0.4–0.5 cm, to 1–2.4 cm in fruit, slender and flexible, sparsely hairy, hairs simple and stellate;

involucellar bractlets distinct, not adnate to calyx, linear to lanceolate, 3–4 × 0.5 mm, shorter than calyx, margins entire, surfaces sparsely ciliate and stellate-puberulent.

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 3–5 mm, 5–6 mm in fruit, lobes incompletely enclosing mericarps, mostly hispid, hairs both simple and stellate, conspicuously long-ciliate, lobes not obviously veined;

petals pale pink or nearly white, drying pinkish or whitish, or faded, veins not darker, 3–6 mm, subequal to slightly longer than calyx;

staminal column 1–1.5 mm, glabrous;

style 10- or 11-branched;

stigmas 10 or 11.

1.2–1.5 mm.

1–1.5 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.

5–7 mm diam.;

mericarps 10 or 11, 1.5–2 mm, margins sharply angled, toothed, not winged, lateral faces radially veined, apical surface strongly rugose-reticulate ridged, surface glabrate or sparsely stellate-puberulent.
