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 or clustered, erect, decumbent-ascending, or reclining, freely rooting proximally, solid, proximally densely stellate-hairy, hairs long, soft, tangled, often 1.5 mm, distally hirsute to subglabrous, hairs smaller and appressed.

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 sometimes purplish, linear-lanceolate, 4–5(–10) × 0.5–1.5 mm;

petioles 10–20 cm on basal leaves, 3 times blade length, gradually reduced distally to 1/2 times blade length;

blades: proximalmost orbiculate or semi-orbiculate to cordate, shallowly 5–7-lobed, 2–10(–15) × 2–10(–15) cm, base cordate, apex rounded, lobe margins coarsely dentate, surfaces densely stellate-hairy abaxially, hairs often simple and appressed adaxially;

mid cauline deeply, palmately 5–7(–9)-lobed, lobes oblong, margins coarsely dentate;

distal cauline smaller, deeply divided ± to base, lobe margins often entire.

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 or ascending, often ± spiciform, usually open, sometimes dense, calyces usually not conspicuously overlapping except sometimes in bud, unbranched or rarely 1–3-branched, 5–20(–30)-flowered, proximalmost 1 or 2 flowers usually leafy-bracted, spaced 1+ cm, elongate, slender and virgate, often 1-sided, 20–25 cm;

bracts often purplish, linear to oblanceolate, usually 2-fid, 3–6 mm, usually equaling pedicels.

3–6(–20) mm;

involucellar bractlets absent.

(2–)3–8(–15) mm;

involucellar bractlets absent.

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.
