stipules sometimes deciduous, lanceolate to ovate, (4–)7–9(–14) × (1.2–)3–4 mm;

petioles of proximal leaves 18–37 cm, 3–5 times as long as blades, distal 5–20 cm, to 1/2–1 times as long as blades;

blades: basal reniform to rounded, unlobed and marginally deeply crenate or very shallowly palmately 5–7-lobed, 6–20 × 6–20 cm, base cordate, apex rounded;

cauline deeply 5–9-lobed, lobes linear-elliptic to oblong-elliptic, margins usually entire, sometimes toothed, surfaces finely, sparsely hairy, hairs mostly simple.

basal and cauline;

stipules deciduous, lanceolate, 4–7(–15) × 1–2 mm;

petioles of proximal leaves 10–20 cm, 3–4 times as long as blades, reduced distally to 1/2 times blade length;

blades: proximal orbiculate, shallowly or deeply 5–9-lobed, 5–10 × 5–10 cm, base wide-cordate to ± truncate, lobe margins coarsely crenate and dentate, apex 2–5-toothed, mid stem largest, 5–7(–9)-lobed, usually incised ± to base, 10–25 × 10–25 cm, lobe margins coarsely dentate to laciniate or entire, surfaces scabrid-hairy, hairs simple or forked, stiff;

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

erect, spiciform, proximally open, distally dense, otherwise calyces not conspicuously overlapping except sometimes in bud, branched, 20+-flowered, proximalmost flowers spaced usually to 1 cm apart, not leafy-bracted, elongate, not 1-sided, 10–20 cm;

bracts single, purple, mm, hairy;

anthers white;

stigmas (6 or)7 or 8.

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.
