Flora of North America species comparison

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 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.

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.

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 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.

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.

(2–)3–8(–15) mm;

involucellar bractlets absent.

(3–)5–10(–15) mm;

involucellar bractlets absent.

bisexual or unisexual and pistillate, plants gynodioecious;

calyx 6–12 mm, densely, finely stellate-hairy, without longer hairs, lobes green or purple-tinged;

petals pink or pinkish lavender to magenta, usually drying purple, usually pale-veined, pistillate 9–10 mm, bisexual 15–28(–30) mm;

staminal column 6–8 mm, hairy;

anthers white;

stigmas 6 or 7(or 8).

usually bisexual, infrequently unisexual and pistillate, plants gynodioecious;

calyx (7–)9–10 mm, to 12–14 mm in fruit, densely stellate-puberulent;
