Flora of North America species comparison

usually several, clustered, erect, often purplish, often thick and hollow proximally, usually proximally ± scabrous, hairs stellate and distally stellate-hairy, sometimes glabrous.

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.

mostly cauline;

stipules persistent or deciduous, lanceolate, 6–8 × 1–1.5 mm;

proximal petioles 25–30 cm, 4–5 times as long as blade, reduced to 7–13 cm on midstem leaves and to 2–3 cm on distalmost leaves, these to 1/2 times as long as blades;

basal blades wide-ovate to orbiculate, shallowly to deeply, palmately 5–7(–9)-lobed, 6–13 × 6–13 cm, lobe margins toothed, teeth rounded, sometimes Ribes-like, base cordate, apex rounded, surfaces: abaxial densely stellate-pubescent, adaxial glabrous or sparsely stellate-pubescent on veins;

cauline blades round, divided nearly to base, 5–9-lobed, lobes again deeply incised to subentire, 10–20 × 10–20 cm, distalmost 5–7-cleft to base.

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.

erect, spiciform, dense, calyces usually conspicuously overlapping in flower and sometimes in fruit, usually 20–30-branched per primary stem, 20+-flowered, elongate, not 1-sided, most flowers usually open at same time, branches relatively short, each spike unit 6 cm, longer in fruit;

bracts ovate-lanceolate to subulate, undivided, 1–6(–10) mm, subequal or longer than pedicels, much shorter than calyx.

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.

1–2(–5) mm;

involucellar bractlets absent.

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

involucellar bractlets absent.

bisexual or unisexual and pistillate, pistillate plants more frequent than bisexual ones, some flowers may be staminate, plants gynodioecious;

calyx urceolate with swollen base especially in young fruit, pistillate 6–8 mm, bisexual 6–10 mm, strongly reticulate-veined, usually finely stellate-puberulent, sometimes glabrate, lobes usually purple tinted;

petals 7 or 8, pale pink, pinkish rose, or rose-purple, usually neither pale-veined nor white at base, pistillate 8–12(–14) mm, staminate or bisexual (10–)11–19(–23) mm;

staminal column 5–6 mm, hairy;

anthers white;

stigmas 7 or 8.

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.

2 mm.

1.5 mm.

6 mm diam.;

mericarps 7 or 8, 3 mm, apical margins ± rounded, sides smooth or slightly reticulate-veined, not pitted, back essentially smooth, very sparsely glandular-puberulent near tip, mucro 0.5–1 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.
