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.

clustered, usually erect or ascending, sometimes proximally decumbent or prostrate, not rooting, solid, sparsely to densely appressed stellate-hairy.

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, persistent, to 10+;

stipules linear-lanceolate to elliptic, 5–6 × 2 mm on proximal stem, 4–5 × 0.5 mm on distal stem;

petiole 5.5–16 cm, basal 3–5 times longer than blades, reduced distally to 1/2 times as long as blades;

blades: basal reniform-orbiculate, palmately (5–)7–9-lobed, deeply incised, (1.5–)2.5–4(–6) × (1.5–)2.5–4(–6) cm, base cordate, margins entire, apex rounded to acute, lobes linear to oblong, again deeply pinnately or ternately 3–5-lobed;

cauline ternately lobed, lobes linear to filiform, narrowest on distalmost leaves, somewhat fleshy, surfaces hairy, hairs appressed, stellate;

distalmost leaf lobes unlobed.

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, open, calyces not conspicuously overlapping except sometimes in bud, usually unbranched, usually 3–9(–15)-flowered, elongate, 1-sided, to 7–25 cm;

bracts usually paired, linear or lanceolate to narrowly ovate, proximal divided to base, distalmost 2-fid or simple, 5 mm, shorter to longer than pedicels.

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

involucellar bractlets absent.

3–8(–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.

usually bisexual or, infrequently, unisexual and pistillate, plants gynodioecious;

calyx (6–)7–10 mm, slightly enlarged in fruit, uniformly minutely stellate-puberulent;

petals pink to rose, pale-veined at least when dry, 9–20(–25) mm, pistillate shortest;

staminal column 3.3–7.5 mm, sparsely stellate-hairy;

anthers pale yellowish to white;

stigmas 6 or 7.

1.5 mm.

1.5–2 mm.
