Flora of North America species comparison

scattered, erect to ascending, base decumbent to erect, usually rooting freely, solid, proximally hairy or glabrate, hairs soft, simple and stellate, distally brittle, easily broken, glabrous-glaucous.

clustered or scattered, erect to ascending, or decumbent to suberect, sometimes rooting, unbranched or branched, solid, usually densely to sparsely hirsute, stellate-hairy, or glabrescent, hairs 1–2 mm, distal stem usually more sparsely hairy to glabrate.

mostly basal or cauline 3 or 4 on proximal 1/3 of stem, much reduced;

stipules wide-lanceolate to ovate, 3–4 × 1–1.5 mm;

petioles of proximal leaves 6–12 cm, 2–4 times as long as blades in basal leaves, those of cauline leaves greatly reduced to 1/2 times or as long as blades;

blade rounded to reniform, palmately (3–)5–7-lobed, usually (1–)2–5(–10) × (1–)2–5(–10) cm, apex rounded, surfaces: abaxial harshly stellate-hairy, adaxial usually simple-haired, basal blades shallowly incised, lobes with 3 deep crenations;

cauline blades usually deeply 3–5(–7)-lobed nearly to base, lobe margins dentate or entire.

basal and/or cauline;

stipules green or purplish, linear-lanceolate or wide-lanceolate to oblong or ovate, 3–8(–12) × 1–3.5(–5) mm, often hairy to ciliate;

petioles of proximalmost leaves (5–)6–15(–30) cm, 3–9 times as long as blades, much reduced distally to 1/2–2 times as long as blade;

blades: proximalmost usually orbiculate, sometimes reniform, unlobed or shallowly lobed, (1–)4–15 × (1–)4–12 cm, base cordate, margins crenate, apex rounded, surfaces hairy, hairs stiff, either or both simple and stellate or forked, lobes cuneate-obovate, margins dentate;

mid stem unlobed or palmately 5–9-lobed, margins coarsely crenate-serrate, lobes toothed or lobed to dissected;

distalmost smaller, sometimes subsessile.

ascending, open, calyces not conspicuously overlapping except sometimes in bud, unbranched or few-branched, loosely (3–)5–10(–20)-flowered, not greatly elongated, 1-sided, 10–20 cm;

bracts narrowly elliptic, shallowly 2-fid, proximal bracts divided to base and often with leaf remnant between, 3–4 mm, usually shorter than to equaling pedicels.

erect or somewhat ascending, dense, subcapitate or spicate especially when young to elongated and open, calyces overlapping or not, not long-pedunculate, usually unbranched, 2–21-flowered, usually light or bright pink to lavender or dark rose-purple, rarely white, pale-veined, 7–20(–30) mm, pistillate 7–11(–30) mm, bisexual 10–25(–30) mm;

staminal column 4–8 mm, hairy;

anthers white to pale pink or pale yellow;

stigmas (6 or)7 or 8(or 9).

3–4(–10) mm;

involucellar bractlets absent.

bisexual or unisexual and pistillate, plants gynodioecious;

calyx 7–10 mm, slightly enlarged in fruit, uniformly, coarsely stellate-puberulent (some rays sometimes longer than others);

petals dark pink, pale-veined at least when dry, pistillate 10–15(–20) mm, bisexual 20–25(–33) mm;

staminal column 4–5 mm, sparsely hairy;

anthers white to pale pink;

stigmas 6 or 7(or 8).

2 mm.

1.5–3 mm.

6–7 mm diam.;

mericarps 6 or 7(or 8), 3–3.5 mm, back not ribbed, roughened, sides and back strongly reticulate-veined-rugose and pitted (honeycomblike), top minutely glandular-puberulent, mucro 0.8–1 mm.

4–8 mm diam.;

mericarps (6 or)7 or 8(or 9), 2.5–4 mm, usually minutely hirtellous, stellate-puberulent, or glandular, rarely glabrous, roughened, sides ± honeycomb-pitted and reticulate-veined, back less so, mucro 0.3–1 mm.
