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.

usually several, clustered, erect, usually purplish tinted especially near base, mostly unbranched, sometimes proximally hollow, base glabrous or sparsely hairy, hairs minute, simple or stellate, more densely scabrous distally.

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.

basal and cauline, ± fleshy;

stipules deciduous, often purplish, lanceolate to linear, 6–11 × 1–3 mm;

petiole often purplish tinted, those of basal leaves to 30 cm, proximalmost 3 times as long as blades, mid cauline 1–2 times as long as blades, distalmost to 1/2 times as long as blades and leaves subsessile;

basal blades orbiculate, unlobed or shallowly 5-lobed, 7–15 × 7–15 cm, margins crenate or dentate, ciliate, surfaces glabrous or sparsely hirsute, hairs sometimes forked, not stellate, mid cauline palmately 7–9-lobed, incised 1/2+ length, 7–12(–17) × 7–12(–17) cm, lobes cuneate, margins coarsely dentate to pinnatifid, apex toothed, surfaces: adaxial sparsely hairy or only on veins, ciliate, distal cauline leaves 3–5-parted nearly to base, lobes narrowly lanceolate to linear, margins coarsely dentate-laciniate.

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, spiciform, dense, especially when young, sometimes elongate, calyces usually conspicuously overlapping in flower and sometimes in fruit, usually branched, 20-flowered, usually several to many open at same time, not 1-sided, 5–20 cm;

bracts purplish, lanceolate to linear, undivided, rarely 2-fid, 4–5 mm, longer than pedicels, shorter than calyx.

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

involucellar bractlets absent.

1–4 mm, to 7–8 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 or often unisexual and pistillate, plants gynodioecious;

calyx somewhat urceolate, 8–9 mm, to 10–12 mm in fruit, lobes strongly reticulate-veined, sparsely stellate-hairy or proximally glabrous, lobe tips usually purple, rarely green, margins ciliate;

petals bright pinkish lavender, drying deep purple, veins not paler, bases not white, pistillate usually 8–10 mm, bisexual (10–)15–20 mm;

staminal column 6–7 mm, hairy;

anthers white;

stigmas (5–)7 or 8(or 9).

1.5 mm.

3 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.

8–9 mm diam.;

mericarps (5–)7 or 8(or 9), 4 mm, smooth, glabrous (rarely sparsely glandular-puberulent), thin-walled, apical margins sharp-edged, not winged, back sometimes slightly wrinkled, mucro 0.8–1.3 mm.
