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.

mostly single, usually erect, sometimes branched distally, solid (sometimes hollow in older, robust plants), sometimes glaucous, proximally densely bristly-hairy, hairs reflexed, stiff, simple, sometimes also coarse, 2–3-rayed, stellate, 1–1.6(–2.5) mm, pustulate, sparser distally, with minute, stellate hairs in inflorescence.

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, some cauline;

stipules usually early-deciduous, linear-lanceolate, 3–7 × 1 mm;

proximal petioles 15–18 cm, 3–4 times as long as blade, distal usually to 1/2 times to as long as blade;

blades: basal rounded, usually palmately 7-lobed, shallowly incised, 4–8 × 4–8 cm, lobes 1.5–2 cm wide, margins crenate-dentate, 3–7-toothed, apices obtuse;

distal 3–10, palmately 5-lobed, deeply incised, 2–6 × 2–6 cm, lobes narrow, linear, 2–3.5 × 2–4 mm, margins entire or 1–5-toothed, surfaces: abaxial stellate-hairy, hairs 6-rayed, 1.5 mm, adaxial hairy, hairs simple, 1.5 mm, distalmost glabrate adaxially and sometimes simple-hairy.

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, open, calyces not conspicuously overlapping except sometimes in bud, unbranched or branched, (5–)10–12(–23)-flowered, elongate, sometimes 1-sided, 10–40 cm;

bracts lanceolate, usually undivided, 3–4 mm, shorter than pedicels and calyx.

1–3(–5) mm;

involucellar bractlets absent.

(3–)5–10(–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.

usually bisexual, infrequently unisexual and pistillate, plants gynodioecious;

calyx (7–)9–10 mm, to 12–14 mm in fruit, densely stellate-puberulent;

petals pale pinkish lavender, often pale-veined especially when dry, pistillate 10–20 mm, bisexual 20–25(–31) mm;

staminal column 7–8(–10) mm, sparsely puberulent;

anthers white;

stigmas (6)7(8).

2.5–3.5 mm.

2.5 mm.

mericarps (6)7(8), 3–4 mm, minutely glandularpuberulent, glabrescent, margins sometimes sharpedged, roughened, strongly reticulate-veined, sides and back deeply pitted, honeycomblike, median line on back but not furrowed, mucro 1 mm.
