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.

single, erect, usually branched distally with erect branches, solid, not glaucous, proximally glabrate, distally usually softly, densely bristly-hirsute, rarely glabrescent.

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.

cauline;

stipules inconspicuous or deciduous, purplish, lanceolate to subulate, 3–12 × 1–2 mm;

petiole 2–7 cm, longest on proximal leaves and gradually reduced distally, proximalmost to 3 times as long as blade, reduced distally to 1/2 times or as long as blade;

blades: proximalmost early-deciduous, orbiculate, unlobed, 1–2.5 × 1–2.5 cm, base cordate, margins crenate, surfaces ± bristly, distal deeply palmately 5–7(–9)-lobed to base, 3–8 × 3–8 cm, lobes linear, margins entire, apex acute, surfaces: abaxially younger blades hirsute, older glabrous except on veins.

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, spiciform, dense, calyces usually overlapping, ca. 20–30-flowered, proximalmost 1 or 2 flowers in leaf axils, not elongate, not 1-sided, 2–5 cm, to 20 cm in fruit;

bracts inconspicuous or deciduous, often purplish, linear, 4–8 × to 2 mm, slightly longer than pedicels, usually 2-fid, sometimes undivided.

2–5(–10) mm;

involucellar bractlets absent.
