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 scattered, ascending to erect, solid, sometimes glaucous, proximally usually long bristly-hirsute, hairs simple or few stellate, rarely glabrous, distally stellate-hairy.

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.

mostly cauline (on reproductive stems), basal present mostly when stems young;

stipules lanceolate to ovate, (3–)4–5 × 0.8–3 mm;

proximal petioles 7–12 cm, 3–4 times blade length, distal usually 1/2–1 times blade length;

blade often grayish green, reniform or reniform-orbiculate, 2.5–6 × 2.5–6 cm, base wide-cordate, margins ciliate, apex rounded overall (lobes can be acute), surfaces softly stellate-hairy to silky villous-hirsute;

basal shallowly, palmately 5-lobed, lobe not 1-sided, 3–8 cm, elongating in fruit;

bracts linear, unlobed or infrequently 2-fid, 2–5 mm, subequal to or longer than pedicels, much shorter than calyx.

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.

1–3(–5) mm;

involucellar bractlets absent.

1–3(–5) mm;

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 unisexual and pistillate, plants gynodioecious;

calyx 5–9 mm, stellate-puberulent and softly long-hirsute with marginal bristles 1.5 mm;

petals magenta-pink, drying dark purple, sometimes pale-veined, 5–15 mm, pistillate darker, 5 mm;

staminal column 3–6 mm, hairy;

anthers white;

stigmas 6–8.

2.5–3.5 mm.

1.5–2 mm.

7–8 mm diam.;

mericarps 5–10, 3.5–4 mm, glabrous or sparsely stellate-puberulent, roughened, prominently reticulate-veined, sides rugose and pitted, back less so, mucro 0.6–0.8 mm.

4–5 mm diam.;

mericarps 6–8, 2.5 mm, glabrous or sparsely stellate-puberulent, sides slightly reticulate-veined, back rougher, pitted, mucro 0.5 mm.
