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 single, erect and sometimes supported by adjacent plants (sprawling), base prostrate or decumbent-ascending to erect, often rooting, solid, not brittle, sometimes ± glaucous distally, proximally stellate-hairy, glabrate, hairs minute or larger and coarse (never simple only), usually 4-rayed, 0.5–1 mm.

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/or cauline, similar in size and shape;

stipules linear to lanceolate, 2–3 × 1.1 mm;

petiole (1–)5–10(–15) cm, longest on proximal leaves, 1–4 times longer on proximal leaves to 1/2 times to as long as blade on distal leaves;

blade usually shallowly to deeply palmately 3–7-lobed usually halfway to base, proximal and distal cauline blades rounded to reniform, 2–3 × 2–5 cm, usually wider than long, base cordate to truncate, margins crenate, apex blunt or rounded, lobes narrowest at base, margins usually apically coarsely toothed, rarely entire, surfaces stellate-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.

ascending or erect, often spiciform, open, calyces not overlapping in flower or fruit, unbranched or branched, 2–15(–30)-flowered, elongate in both flower and fruit, usually 1-sided, 6–11(–30) cm;

bracts leaflike to linear, usually 2-fid, (2–)3–5(–15) mm.

1–3(–5) mm;

involucellar bractlets absent.

2–5(–10) 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 5–12 mm, uniformly densely stellate-puberulent;

petals pink to pale purple, pale-veined, (5–)10–28 mm, pistillate flowers darker, 5–15 mm;

staminal column 4–5 mm, stellate-puberulent;

anthers white;

stigmas (6 or)7 or 8.

2.5–3.5 mm.

1.5–2.8 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.

6–8 mm diam.;

mericarps (6 or)7 or 8, 3–4 mm, usually glandular-puberulent to stellate-puberulent, sometimes glabrous, roughened, strongly reticulate-veined, sides and back pitted, mucro 0.5–1 mm.
