Flora of North America species comparison

single or clustered, erect, base often decumbent-ascending, solid (proximally hollow on older stems), proximally densely bristly-hirsute, hairs simple or forked, 0.5–1 mm, sometimes mixed with minute, stellate hairs, sometimes glabrous and glaucous in age, hairs usually more appressed, simple, stellate, or sparse distally.

mostly cauline;

stipules lanceolate, 4–11 × 1–1.5 mm;

petioles of proximal leaves 15–20 cm, 2–3 times as long as blades, distal reduced to 0.5–10 cm, 1/2 times to as long as blades;

blade 10–15 × 10–15 cm, smaller distally, surfaces scabrid-hairy, hairs dense, simple or stellate, stiff, stellate hairs mostly on adaxial surfaces, proximal blades orbiculate, shallowly to deeply palmately 7–9-lobed, 5–15 × 5–15 cm, base cordate, margins coarsely crenate-serrate, lobes apically 2–5-toothed;

distal cauline leaves variable, mid blades usually palmately divided nearly to base into 5–7 cuneate lobes, 15 × 15 cm, lobes deeply cut to laciniately dissected, distal blades divided into (3–)5–7 linear, marginally subentire segments, surfaces glabrescent or with few hairs on abaxial surface veins, ciliate.

erect, open, spiciform, calyces not conspicuously overlapping except sometimes in bud, often branched from distal leaves, 15+-flowered, elongate, not 1-sided, 10–35 cm, proximal flowers spaced several cm apart, not leafy-bracted;

bracts linear, distal undivided or 2-fid, proximal separate to base, 4–10 mm, usually equaling or longer than pedicels.

erect, spicate, dense, calyces sometimes overlapping, unbranched or branched, distal stem sometimes leafless, many-flowered, not 1-sided, 2–10 cm, elongating at maturity;

bracts green or purplish, ovate to wide-elliptic, usually 2-fid, sometimes undivided, 2–6(–12) × 2–5 mm.

3–6(–20) mm;

involucellar bractlets absent.

(2–)4–5 mm;

involucellar bractlets absent.

bisexual or unisexual and pistillate, plants gynodioecious;

calyx 5–9 mm, pistillate 5–7 mm, bisexual 6–9 mm, 8–10 mm in fruit, uniformly, densely stellate-hairy or with coarser, longer, stellate hairs to 2 mm;

petals usually not overlapping, nearly white to pale pink or pale lavender, pistillate 9–12 mm, bisexual 13–25 mm;

staminal column 5–7 mm, hairy;

anthers white to pale pink;

stigmas (6 or)7 or 8.

bisexual or infrequently unisexual and pistillate, plants gynodioecious;

calyx often purple tinted or scarious, 4–12 mm, silky strigose-bristly at base and on veins, stellate-puberulent;

petals usually pale purple or pink, rarely white, base pale or white, (9–)10–25 mm, pistillate shortest;

stamens: outer filaments connate to apex, tube funnel-like, with continuous rim to which unstalked anthers attach;

staminal column 4–9 mm, hairy in proximal 1/2;

anthers white to pale purple;

stigmas 5–9.

2.5 mm.

2–3.5 mm.

7–8 mm diam.;

mericarps (6 or)7 or 8, 3.5 mm, roughened, sides prominently reticulate-rugose and pitted, back less so and glandular-puberulent, mucro 0.5–1 mm.

5–9 mm diam.;

mericarps 5–9, often purple tinted, 2.5–4.5 mm, glabrous, not especially roughened, sides reticulate-veined, back deeply longitudinally grooved, mucro often appressed, 0.5 mm.
