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, erect to slightly ascending, base erect to decumbent-ascending, usually unbranched, (plants nearly scapose), solid, long-bristly with hairs often 2 mm, sometimes also stellate-hairy near base, usually becoming finely hispid 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.

mostly basal, cauline 1–3;

stipules lanceolate, 3–5 × 1 mm;

petiole 6–9 cm, basal 2 times blade length, cauline 1/2 times blade length;

blade usually orbiculate, 2–5(–6) × 2–5(–6) cm, base cordate, apex rounded, basal deeply dissected into 3–7 primary lobes, each less deeply incised and somewhat ternate, ultimate segments linear to oblong-elliptic, margins entire, distal blades repeatedly dissected with linear segments, surfaces densely hirtellous and stellate-hairy abaxially, less hairy with mostly simple hairs adaxially.

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 or ascending, spiciform, initially dense, later open, calyces not conspicuously overlapping except sometimes in fruit, usually unbranched, usually 20+-flowered, proximal flowers remotely, evenly spaced, elongated in fruit, often 1-sided if ascending and not 1-sided when strictly erect, 15–30(–40) cm, elongating with fruits spaced, axis often wine-red;

bracts linear, usually undivided, 2.5–4 mm, usually ± equaling or longer than pedicels.

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

involucellar bractlets absent.

1–2(–3) 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, similar in size, plants gynodioecious;

calyx usually wine-red, 4–5(–7) mm, usually not accrescent, finely stellate-puberulent, marginal hairs longer and often simple;

petals dark rose-pink, sometimes pale-veined, 7–10(–12) mm;

staminal column 3–5 mm, sparsely hairy;

anthers white;

stigmas 5–8.

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.

5 mm diam.;

mericarps 5–8, somewhat inflated, 2.5 mm, glabrous, smooth, back lightly grooved, not reticulate-veined or pitted, mucro 0.2–0.3 mm.
