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.

1–20, clustered, erect to ascending or decumbent, usually not rooting, solid, proximally hairy, hairs simple, stellate, or mixed, 0.5–1.5 mm, distally usually stellate-hairy or glabrous.

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 basal, cauline to 5, (plant sometimes scapose);

stipules linear to lanceolate, 2–8 × 1–1.5 mm;

petioles of basal leaves 5–10(–25) cm, often 5 times blade length, distally reduced to 1/2 times blade length;

blade orbiculate to reniform, 2–6(–8) × 2–6(–8) cm, base cordate, apex rounded, surfaces stellate-hairy abaxially, moderately minutely stellate-hairy to appressed-hairy adaxially, basal leaves usually shallowly 7-lobed, sometimes unlobed and margins crenate, cauline smaller, palmately 3–5-lobed ± to base, lobe margins entire or incised.

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.

usually ascending, ± open, calyces not conspicuously overlapping except sometimes in bud, branched or unbranched, 10+-flowered, most flowers spaced 1+ cm apart, elongated, extending well above leaves, narrow, often 1-sided, (15–)30–45 cm;

bracts lanceolate, mostly 2-fid, proximal bracts divided ± to base, distal sometimes undivided.

1–3(–5) mm;

involucellar bractlets absent.

2–8(–15) 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 6–10 mm, densely to sparsely stellate-puberulent, hairs usually longer, coarser, 2–4-rayed especially at margins and over veins;

petals pinkish rose to pinkish lavender or magenta, pale-veined or not, base often white, 10–25 mm, pistillate darker, 6–15 mm, bisexual 12–25(–30) mm;

staminal column 5–6 mm, puberulent;

anthers white;

stigmas (6 or)7–9.

2.5–3.5 mm.

2.5 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.
