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, clustered in older plants, erect, sometimes branched distally, solid, glabrous or moderately hirsute, hairs retrorse, simple proximally, becoming ± finely stellate-hairy 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 mostly cauline, not evenly arrayed;

stipules deciduous, ovate, 10 × 2–2.5 mm;

petiole (4–)6–18 cm, usually 1/2 times to as long as blade;

petals often not overlapping, white to pale pinkish, drying yellowish, 10–20 mm;

staminal column 6–9 mm, hairy;

anthers bluish pink;

stigmas 6–9.

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.

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.

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.

5–7 mm diam.;

mericarps 6–9, 3–5.5 mm, sides smooth or slightly reticulate-veined, back less so, not pitted, top minutely hairy, mucro 0.5–0.8 mm.
