Flora of North America species comparison

usually single, erect and sometimes supported by adjacent plants (sprawling), base prostrate or decumbent-ascending to erect, often rooting, solid, not brittle, sometimes ± glaucous distally, proximally stellate-hairy, glabrate, hairs minute or larger and coarse (never simple only), usually 4-rayed, 0.5–1 mm.

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.

basal and/or cauline, similar in size and shape;

stipules linear to lanceolate, 2–3 × 1.1 mm;

petiole (1–)5–10(–15) cm, longest on proximal leaves, 1–4 times longer on proximal leaves to 1/2 times to as long as blade on distal leaves;

blade usually shallowly to deeply palmately 3–7-lobed usually halfway to base, proximal and distal cauline blades rounded to reniform, 2–3 × 2–5 cm, usually wider than long, base cordate to truncate, margins crenate, apex blunt or rounded, lobes narrowest at base, margins usually apically coarsely toothed, rarely entire, surfaces stellate-puberulent.

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.

ascending or erect, often spiciform, open, calyces not overlapping in flower or fruit, unbranched or branched, 2–15(–30)-flowered, elongate in both flower and fruit, usually 1-sided, 6–11(–30) cm;

bracts leaflike to linear, usually 2-fid, (2–)3–5(–15) mm.

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.

2–5(–10) mm;

involucellar bractlets absent.

(2–)3–8(–15) mm;

involucellar bractlets absent.

bisexual or unisexual and pistillate, plants gynodioecious;

anthers white;

stigmas (6 or)7 or 8.
