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.

often single, usually scattered, erect, usually unbranched, solid or somewhat hollow in age, proximally densely, finely stellate-hairy, hairs spreading, distally glaucous, glabrous.

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, mostly on abaxially, bristly-hirsute adaxially.

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, open, calyces not conspicuously overlapping except sometimes in bud, usually unbranched, loosely 10+-flowered, flowers 1+ cm apart, elongate, sometimes 1-sided, 30–40(–45) cm;

bracts inconspicuous, lanceolate to linear, distal unlobed, 2–4 mm, proximal divided ± to base, 4–6 mm, usually equaling or shorter than pedicels.
