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.

single, erect, sometimes branched distally, solid, short-stellate-puberulent and long, soft bristly-hairy, distally with multicellular trichomes intermixed, hairs erect.

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.

cauline, 3–5 per stem;

stipules linear-filiform, undivided or rarely few-divided in robust plants, 3–5 × 1 mm;

petiole 2–4.5(–6) cm, usually 1–2 times as long as blade;

blades: proximalmost orbiculate, unlobed, 1–2.5 × 1–2.5 cm, base cordate with narrow sinus, margins crenate, apex rounded;

other proximals rounded, unlobed or shallowly palmately 7–9-lobed, 2.5–4.8(–6) × 2.5–4.8(–6) cm, margins coarsely crenate, sinus wide to narrow, surfaces stellate-hairy;

distals gradually reduced, orbiculate, more deeply 3-lobed, 1.5–2.5 × 1.5–2.5 cm, lobes obovate, apically widened to nearly truncate and narrowed to base, margins entire, apex 2–5-toothed, teeth subequal.

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 to ascending, usually open, calyces not overlapping except possibly in bud, unbranched or infrequently branched, 5–12-flowered per branch, not especially elongate, usually 1-sided, 5–10 cm, to 5–15 cm in fruit, 1/2 times plant height;

bracts linear-filiform, undivided or rarely few-divided in robust plants, (3–)7–11 mm, longer than pedicels, usually much shorter than calyx, not involucrelike, densely stellate-hairy and pilose-hirsute.

3–6(–20) mm;

involucellar bractlets absent.

2–4 mm, to 5–6 mm in fruit;

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;

calyx 8–10 mm, to 11–14 mm in fruit, lobe base within with conspicuous, purplish spot 1–2 mm wide, hairy, hairs glandular and non-glandular, multicellular as in inflorescence;

petals dark pink, without pale veins, with or without reddish basal spot, 10–22(–26) mm;

filaments connate to apex of tube;

staminal column 3–5 mm, hairy, hairs relatively long, simple;

anthers white;

stigmas 4 or 5.

2.5 mm.

1.5–2 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.

5–7 mm diam.;

mericarps 4 or 5, usually tinted pink when fresh, 3–4 mm, usually glabrous, back reticulate-veined, pitted, with prominent midvein, mucro absent but with 1–5 minute bristles in its place.
