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.

scattered, erect to ascending, base decumbent to erect, usually rooting freely, solid, proximally hairy or glabrate, hairs soft, simple and stellate, distally brittle, easily broken, glabrous-glaucous.

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.

mostly basal or cauline 3 or 4 on proximal 1/3 of stem, much reduced;

stipules wide-lanceolate to ovate, 3–4 × 1–1.5 mm;

petioles of proximal leaves 6–12 cm, 2–4 times as long as blades in basal leaves, those of cauline leaves greatly reduced to 1/2 times or as long as blades;

blade rounded to reniform, palmately (3–)5–7-lobed, usually (1–)2–5(–10) × (1–)2–5(–10) cm, apex rounded, surfaces: abaxial harshly stellate-hairy, adaxial usually simple-haired, basal blades shallowly incised, lobes with 3 deep crenations;

cauline blades usually deeply 3–5(–7)-lobed nearly to base, lobe margins dentate or entire.

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.

ascending, open, calyces not conspicuously overlapping except sometimes in bud, unbranched or few-branched, loosely (3–)5–10(–20)-flowered, not greatly elongated, 1-sided, 10–20 cm;

bracts narrowly elliptic, shallowly 2-fid, proximal bracts divided to base and often with leaf remnant between, 3–4 mm, usually shorter than to equaling pedicels.

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

involucellar bractlets absent.

3–4(–10) mm;

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 or unisexual and pistillate, plants gynodioecious;

calyx 7–10 mm, slightly enlarged in fruit, uniformly, coarsely stellate-puberulent (some rays sometimes longer than others);

petals dark pink, pale-veined at least when dry, pistillate 10–15(–20) mm, bisexual 20–25(–33) mm;

staminal column 4–5 mm, sparsely hairy;

anthers white to pale pink;

stigmas 6 or 7(or 8).

1.5 mm.

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.

6–7 mm diam.;

mericarps 6 or 7(or 8), 3–3.5 mm, back not ribbed, roughened, sides and back strongly reticulate-veined-rugose and pitted (honeycomblike), top minutely glandular-puberulent, mucro 0.8–1 mm.
