distalmost 5–7-lobed, lobes linear, subentire, margins ciliate, surfaces glabrescent or with few hairs on abaxial veins.

basal and cauline, basal sometimes deciduous, cauline 3+;

stipules usually deciduous, linear to lanceolate, 4–6(–14) × 0.5–1(–2) mm;

petioles of basal and proximal leaves (5–)7–10(–35) cm, 3–5 times as long as blades, reduced distally, distalmost leaves sometimes subsessile;

blade cordate or reniform-orbiculate, 3–10(–15) × 3–10(–15) cm, base cordate, apex rounded, lobe apex often acute, surfaces glabrous or sparsely hairy, hairs minute, simple, forked, or stellate, proximal usually shallowly palmately 5–7(–9)-lobed, sometimes unlobed with margins crenate;

midstem more deeply (3–)5–9-lobed, lobes again palmately or pinnately lobed, distalmost unlobed or 3(–5)-lobed, segments unlobed or deeply lobed, narrow.

erect, spiciform or subcapitate, dense, calyces usually conspicuously overlapping in flower and sometimes in fruit, branched, ca. 10-flowered, flowers/calyces overlapping, not 1-sided, 3–7(–10) cm, elongated in fruit;

bracts lanceolate-elliptic, undivided, 3–8 mm, longer than pedicels, often longer than young flower buds, ± equaling calyx.

erect, usually spiciform, sometimes subcapitate, congested in bud, dense, calyces sometimes conspicuously overlapping in flower and sometimes in fruit, to open and elongate, few-branched or unbranched, 10–20+-flowered, flowers opening and closing sequentially from base to apex, sometimes 3–10 open on same day, not leafy-bracted, not 1-sided, (1.5–)10–30 cm, elongating in flower or fruit;

bracts linear to linear-lanceolate, undivided to 2-fid, proximal sometimes divided to base, 4–6(–7) mm, sometimes exceeding flower buds, usually equaling or longer than pedicels, shorter than calyx.

1–2 mm, to 4 mm in fruit;

involucellar bractlets absent.

involucellar bractlets absent.
