Flora of North America species comparison

single, scattered, erect, usually purple tinted proximally, hollow especially towards base, pithy distally, 10–14 mm diam. just distal to base, often glaucous, proximally densely retrorsely bristly-hairy and stellate-hairy, hairs pustulate, 1.5–2.5 mm, distally sometimes glabrous.

clustered or scattered, erect to ascending, or decumbent to suberect, sometimes rooting, unbranched or branched, solid, usually densely to sparsely hirsute, stellate-hairy, or glabrescent, hairs 1–2 mm, distal stem usually more sparsely hairy to glabrate.

mostly cauline, basal usually absent;

stipules deciduous, with pink band on stem at base, narrowly lanceolate, (3.5–)5(–8) × 0.7(–1.5) mm;

petioles of proximal leaves 6–8 cm, those of midstem leaves 10–14 cm, 2 times to as long as blade, apex curved with swollen portion or pulvinus 5–6 × 1.8 mm;

blades of proximalmost cauline leaves rounded, shallowly, palmately 4- or 5-lobed, 0.5–0.7 × 0.5–0.7 cm, lobe margins irregularly, sparsely dentate, apices rounded, mid-cauline blades 5–7-lobed, 6.5–12 × 10–13 cm, wider than long, gradually reduced distally, lobes straplike, divided 3/4 to base, lobes 5.5 × 1.5–1.8 cm, margins coarsely dentate, surfaces sparsely, minutely hispid and stellate-puberulent, distal leaves deeply 5-lobed, otherwise similar in shape, leaves immediately below inflorescence greatly reduced, irregularly 2- or 3-lobed.

basal and/or cauline;

stipules green or purplish, linear-lanceolate or wide-lanceolate to oblong or ovate, 3–8(–12) × 1–3.5(–5) mm, often hairy to ciliate;

petioles of proximalmost leaves (5–)6–15(–30) cm, 3–9 times as long as blades, much reduced distally to 1/2–2 times as long as blade;

blades: proximalmost usually orbiculate, sometimes reniform, unlobed or shallowly lobed, (1–)4–15 × (1–)4–12 cm, base cordate, margins crenate, apex rounded, surfaces hairy, hairs stiff, either or both simple and stellate or forked, lobes cuneate-obovate, margins dentate;

mid stem unlobed or palmately 5–9-lobed, margins coarsely crenate-serrate, lobes toothed or lobed to dissected;

distalmost smaller, sometimes subsessile.

erect, spiciform, open, calyces usually not overlapping, usually branched, branches 14–18 cm, each branch 10–20 flowered, not 1-sided, elongate, 5–20 cm;

bracts 1, usually undivided, narrowly lanceolate, often 2-fid, 2.5 mm, equaling or slightly longer than pedicel, much shorter than calyx.

erect or somewhat ascending, dense, subcapitate or spicate especially when young to elongated and open, calyces overlapping or not, not long-pedunculate, usually unbranched, 2–21-flowered, usually light or bright pink to lavender or dark rose-purple, rarely white, pale-veined, 7–20(–30) mm, pistillate 7–11(–30) mm, bisexual 10–25(–30) mm;

staminal column 4–8 mm, hairy;

anthers white to pale pink or pale yellow;

stigmas (6 or)7 or 8(or 9).

2–3(–5) mm;

involucellar bractlets absent.

bisexual or unisexual and pistillate, plants gynodioecious;

calyx 5–6 mm, to 8 mm in fruit, uniformly, densely stellate-puberulent, surface obscured;

petals pale pink, pale-veined, pistillate 7–9 mm, bisexual (10–)14–20(–25) mm;

staminal column 6–8 mm, stellate-puberulent;

anthers white to cream or pale yellow;

stigmas (6)7 or 8.

1.5 mm.

1.5–3 mm.

6–7 mm diam.;

mericarps (6)7 or 8, sides 3 mm, thick, back and margins thick, rounded, reticulate-veined, pitted, back with prominent groove, top sparsely glandular-stellate-puberulent, mucro 1 mm.

4–8 mm diam.;

mericarps (6 or)7 or 8(or 9), 2.5–4 mm, usually minutely hirtellous, stellate-puberulent, or glandular, rarely glabrous, roughened, sides ± honeycomb-pitted and reticulate-veined, back less so, mucro 0.3–1 mm.
