Flora of North America species comparison

single or clustered, erect, base often decumbent-ascending, solid (proximally hollow on older stems), proximally densely bristly-hirsute, hairs simple or forked, 0.5–1 mm, sometimes mixed with minute, stellate hairs, sometimes glabrous and glaucous in age, hairs usually more appressed, simple, stellate, or sparse distally.

scattered, ascending-decumbent or creeping, freely rooting, solid, flowering stems ascending to erect, proximal and midstem densely spreading-long-hirsute, bristles 2–3 mm, often on swollen pads, rarely subglabrous, base without stellate hairs, distally somewhat stellate-puberulent.

mostly cauline;

stipules lanceolate, 4–11 × 1–1.5 mm;

petioles of proximal leaves 15–20 cm, 2–3 times as long as blades, distal reduced to 0.5–10 cm, 1/2 times to as long as blades;

blade 10–15 × 10–15 cm, smaller distally, surfaces scabrid-hairy, hairs dense, simple or stellate, stiff, stellate hairs mostly on adaxial surfaces, proximal blades orbiculate, shallowly to deeply palmately 7–9-lobed, 5–15 × 5–15 cm, base cordate, margins coarsely crenate-serrate, lobes apically 2–5-toothed;

distal cauline leaves variable, mid blades usually palmately divided nearly to base into 5–7 cuneate lobes, 15 × 15 cm, lobes deeply cut to laciniately dissected, distal blades divided into (3–)5–7 linear, marginally subentire segments, surfaces glabrescent or with few hairs on abaxial surface veins, ciliate.

basal and cauline;

stipules on prostrate stems wide-lanceolate to ovate, 5–7 × 2–5 mm, elsewhere 3–6 × 1.3–2 mm;

petiole 3–8(–15) cm, longest on basal leaves, proximalmost 3 times blade length, reduced distally;

blades: proximalmost suborbiculate, unlobed or very shallowly lobed, 2.5–5 × 2.5–5 cm, base wide-cordate, margins deeply crenate, apex rounded, surfaces usually bristly, hairs long, simple, to subglabrous, not stellate-hairy;

distal rather similar to proximalmost or more deeply palmately 3–5(–7)-lobed or toothed, lobes simple or 3-dentate.

erect, open, spiciform, calyces not conspicuously overlapping except sometimes in bud, often branched from distal leaves, 15+-flowered, elongate, not 1-sided, 10–35 cm, proximal flowers spaced several cm apart, not leafy-bracted;

bracts linear, distal undivided or 2-fid, proximal separate to base, 4–10 mm, usually equaling or longer than pedicels.

erect, open or some flowers overlapping, calyces not conspicuously overlapping except sometimes in bud, unbranched, usually 2–10-flowered, flowers 1+ cm apart, not much elongated, usually 1-sided, (5–)10–20 cm;

bracts linear or narrowly oblong-lanceolate, 2-fid, usually inrolled, proximal separated to base, 2–4 mm, usually equaling or slightly longer than pedicels, much shorter than calyx.

3–6(–20) mm;

involucellar bractlets absent.

2–5 mm;

involucellar bractlets absent.

bisexual or unisexual and pistillate, plants gynodioecious;

calyx 5–9 mm, pistillate 5–7 mm, bisexual 6–9 mm, 8–10 mm in fruit, uniformly, densely stellate-hairy or with coarser, longer, stellate hairs to 2 mm;

petals usually not overlapping, nearly white to pale pink or pale lavender, pistillate 9–12 mm, bisexual 13–25 mm;

staminal column 5–7 mm, hairy;

anthers white to pale pink;

stigmas (6 or)7 or 8.

bisexual;

calyx (6.5–)8–10 mm, somewhat accrescent, stellate-puberulent, marginal hairs longer, sometimes few glandular, multicellular, lobes sometimes dull purplish at tips;

petals dark pink to pale lavender-pink, usually pale-veined, 12–20 mm;

staminal column 6–7 mm, minutely hirtellous;

anthers white;

stigmas (6–)8–10.

2.5 mm.

1.5–2 mm.

7–8 mm diam.;

mericarps (6 or)7 or 8, 3.5 mm, roughened, sides prominently reticulate-rugose and pitted, back less so and glandular-puberulent, mucro 0.5–1 mm.

6 mm diam.;

mericarps (6–)8–10, 3 mm, roughened, top, back, mucro densely stellate-puberulent, deeply reticulate-veined, pitted, mucro 1 mm.
