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.

mostly single, usually erect, sometimes branched distally, solid (sometimes hollow in older, robust plants), sometimes glaucous, proximally densely bristly-hairy, hairs reflexed, stiff, simple, sometimes also coarse, 2–3-rayed, stellate, 1–1.6(–2.5) mm, pustulate, sparser distally, with minute, stellate hairs in inflorescence.

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.

mostly basal, some cauline;

stipules usually early-deciduous, linear-lanceolate, 3–7 × 1 mm;

proximal petioles 15–18 cm, 3–4 times as long as blade, distal usually to 1/2 times to as long as blade;

blades: basal rounded, usually palmately 7-lobed, shallowly incised, 4–8 × 4–8 cm, lobes 1.5–2 cm wide, margins crenate-dentate, 3–7-toothed, apices obtuse;

distal 3–10, palmately 5-lobed, deeply incised, 2–6 × 2–6 cm, lobes narrow, linear, 2–3.5 × 2–4 mm, margins entire or 1–5-toothed, surfaces: abaxial stellate-hairy, hairs 6-rayed, 1.5 mm, adaxial hairy, hairs simple, 1.5 mm, distalmost glabrate adaxially and sometimes simple-hairy.

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, calyces not conspicuously overlapping except sometimes in bud, unbranched or branched, (5–)10–12(–23)-flowered, elongate, sometimes 1-sided, 10–40 cm;

bracts lanceolate, usually undivided, 3–4 mm, shorter than pedicels and calyx.

3–6(–20) mm;

involucellar bractlets absent.

(3–)5–10(–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.
