Flora of North America species comparison

several, scattered, erect, arising from rhizome apices, usually slightly hollow, densely, harshly bristly-hirsute, hairs stiff, pustular, simple, forked, or stellate, often 2–2.5 mm.

usually several, clustered, erect, usually purplish tinted especially near base, mostly unbranched, sometimes proximally hollow, base glabrous or sparsely hairy, hairs minute, simple or stellate, more densely scabrous distally.

basal and cauline;

stipules linear-subulate, 6–8 × 1–1.5 mm;

petioles of proximal leaves 20–30 cm, 3 times as long as blades, reduced distally to 1/2 times as long as blades;

blades: basal and proximalmost orbiculate to reniform, shallowly 5–9-lobed, 10–15 × 10–15 cm, thick, base narrowly cordate, lobe margins coarsely crenate-dentate, apex rounded, surfaces coarsely hirsute, hairs stiff;

distal orbiculate, deeply palmately 5–7-lobed, incised ± to base, lobes sometimes lobed again, base cuneate, apex acute, deeply 2–3-toothed, surfaces long-hirsute or with 2–4-rayed, stellate hairs abaxially.

basal and cauline, ± fleshy;

stipules deciduous, often purplish, lanceolate to linear, 6–11 × 1–3 mm;

petiole often purplish tinted, those of basal leaves to 30 cm, proximalmost 3 times as long as blades, mid cauline 1–2 times as long as blades, distalmost to 1/2 times as long as blades and leaves subsessile;

basal blades orbiculate, unlobed or shallowly 5-lobed, 7–15 × 7–15 cm, margins crenate or dentate, ciliate, surfaces glabrous or sparsely hirsute, hairs sometimes forked, not stellate, mid cauline palmately 7–9-lobed, incised 1/2+ length, 7–12(–17) × 7–12(–17) cm, lobes cuneate, margins coarsely dentate to pinnatifid, apex toothed, surfaces: adaxial sparsely hairy or only on veins, ciliate, distal cauline leaves 3–5-parted nearly to base, lobes narrowly lanceolate to linear, margins coarsely dentate-laciniate.

erect, spiciform to subcapitate, dense, calyces usually conspicuously overlapping in flower and sometimes in fruit, proximals usually long-pedunculate, unbranched or branched, 20+-flowered, 10+ flowers usually open on spike at same time, not interrupted, not 1-sided, usually to 8 cm, usually not elongate but sometimes slightly elongated in some populations and to 20 cm in fruit;

bracts paired or single, linear, distal undivided, proximal distinct to base, 6 mm, mostly slightly longer than pedicels.

erect, spiciform, dense, especially when young, sometimes elongate, calyces usually conspicuously overlapping in flower and sometimes in fruit, usually branched, 20-flowered, usually several to many open at same time, not 1-sided, 5–20 cm;

bracts purplish, lanceolate to linear, undivided, rarely 2-fid, 4–5 mm, longer than pedicels, shorter than calyx.

1–3(–5) mm;

involucellar bractlets absent.

1–4 mm, to 7–8 mm in fruit;

involucellar bractlets absent.

bisexual or unisexual and pistillate, plants gynodioecious;

calyx often purple tinted, 9–11 mm, to 11–16 mm in fruit, margins ciliate, hairs 1–2 mm, surfaces finely stellate-hairy at base and with coarser, longer, simple and stellate hairs apically;

petals usually pale pink to rose-lavender, rarely white, slightly or not pale-veined, (9–)10–21 mm, pistillate often 9–14 mm;

staminal column 5–7(–10) mm, hairy;

anthers white;

stigmas 5–10.

bisexual or often unisexual and pistillate, plants gynodioecious;

calyx somewhat urceolate, 8–9 mm, to 10–12 mm in fruit, lobes strongly reticulate-veined, sparsely stellate-hairy or proximally glabrous, lobe tips usually purple, rarely green, margins ciliate;

petals bright pinkish lavender, drying deep purple, veins not paler, bases not white, pistillate usually 8–10 mm, bisexual (10–)15–20 mm;

staminal column 6–7 mm, hairy;

anthers white;

stigmas (5–)7 or 8(or 9).
