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.

single, erect, usually branched distally, solid, both short-stellate-puberulent and long soft bristly-hairy, hairs erect.

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, early-deciduous, and cauline;

mid to distal stem stipules divided into 2–5 filiform or linear segments, involucrelike, 10+ × 1 mm;

petiole (4–)6–20(–50) cm, usually 1/2 times to as long as blade;

basal leaf blades orbiculate, unlobed, 1–2.5 × 1–2.5 cm, base cordate, margins crenate, apex rounded;

cauline leaf blades orbiculate, palmately 5–7-lobed, (1–)2–6 × (1–)2–6 cm, lobes linear distally, sometimes 3-toothed or -lobed, then midtooth or lobe much longer than laterals, margins entire, surfaces bristly-puberulent.

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, dense, calyces overlapping, occasionally short-branched, clusters to 10-flowered, subumbellate to elongate in age, not 1-sided;

bracts linear or filiform, palmately 2–7-lobed, 8–12 mm, lobes linear, usually becoming involucrelike, 1–2.5 cm, subequal to or longer than calyx.

1–3(–5) mm;

involucellar bractlets absent.

1–3 mm, (short branches may easily be mistaken for pedicels);

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;

calyx 8–12 mm, not much accrescent, lobes often with narrow purple line or spot at lobe base inside, outer surface bristly-hairy and stellate-puberulent, seldom densely glandular, multicellular hairs usually few or absent;

petals dark pink to deep purple, veins often paler, darker patch sometimes at base, 20–35 mm;

staminal column 4–6 mm, hairy;

anthers sessile on rim, white;

stigmas 5 or 6.

2.5–3.5 mm.

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.

6–7 mm diam.;

mericarps 5 or 6, sometimes pinkish when fresh, 2.5 mm, glabrous, back minutely hairy, back and sides reticulate-veined, back with prominent midvein, not pitted, mucro absent.
