Flora of North America species comparison

1–several, clustered, erect or ascending from slightly decumbent base, unbranched or branched, solid, infrequently hollow in robust plants, sometimes glaucous, proximally usually coarsely, densely to moderately bristly-hirsute, hairs often pustulose to sparsely stellate-hairy, sometimes glabrous, distally usually minutely puberulent or glabrous.

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

basal and cauline, cauline 3+;

stipules linear to wide-lanceolate, 4–8 × 1–2 mm;

petioles of proximalmost leaves 10–25 cm, reduced distally to shorter than blade, to 5 times blade length;

blade fleshy, margins often short-ciliate, surfaces sparsely hairy, less so adaxially, hairs simple-hirsute to stellate, appressed, basal orbiculate, unlobed, margins crenate, or shallowly 5–7(–9)-lobed, (1.5–) 2–6(–8) × (1.5–)2–6(–8) cm, base cordate, apex rounded, lobes with margins crenate to dentate, apex acute, distal cauline highly reduced or not, deeply, palmately (3–)5–7(–9)-lobed, smaller, ultimate divisions linear, margins entire.

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 to ascending, open or dense, calyces not conspicuously overlapping except sometimes in bud, unbranched or branched, 20+-flowered, proximal flowers spaced 1+ cm apart, elongate, sometimes 1-sided, 10–25 cm, elongating in fruit;

bracts linear to lanceolate, undivided or deeply 2-fid, 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.

5–8(–40) mm, equaling to much longer than calyx in fruit;

involucellar bractlets absent.

2–4 mm, to 5–6 mm in fruit;

involucellar bractlets absent.

bisexual or, less frequently, unisexual and pistillate, plants gynodioecious;

calyx 5–8(–10) mm, often accrescent, sparsely hairy, hairs simple, to 1 mm, pustulose, sometimes small, stellate, infrequently glandular, surface not obscured;

petals pale pinkish rose or pale lavender-purple, bases paler, rarely white, veins usually pale, (6–)10–20(–25) mm, pistillate 8–12 mm, bisexual 18–20 mm;

staminal column 5–6 mm, hispid-puberulent;

anthers white;

stigmas (7 or)8 or 9.

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.

1.5 mm.

1.5–2 mm.

5 mm diam.;

mericarps (7 or)8 or 9, 2–3 mm, ± glabrous, sides thin, smooth to slightly reticulate-veined, not pitted, mucro 0.5–0.8(–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.
