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.

single, erect, usually branched distally, solid, both short-stellate-puberulent and long soft bristly-hairy, hairs erect.

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, early-deciduous, and cauline;

mid to distal stem stipules divided into 2–5 filiform or linear segments, involucrelike, 10+ × 1 mm;

petiole (4–)6–20(–50) cm, usually 1/2 times to as long as blade;

basal leaf blades orbiculate, unlobed, 1–2.5 × 1–2.5 cm, base cordate, margins crenate, apex rounded;

cauline leaf blades orbiculate, palmately 5–7-lobed, (1–)2–6 × (1–)2–6 cm, lobes linear distally, sometimes 3-toothed or -lobed, then midtooth or lobe much longer than laterals, margins entire, surfaces bristly-puberulent.

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, dense, calyces overlapping, occasionally short-branched, clusters to 10-flowered, subumbellate to elongate in age, not 1-sided;

bracts linear or filiform, palmately 2–7-lobed, 8–12 mm, lobes linear, usually becoming involucrelike, 1–2.5 cm, subequal to or longer than calyx.

1–2(–5) mm;

involucellar bractlets absent.

1–3 mm, (short branches may easily be mistaken for pedicels);

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;

calyx 8–12 mm, not much accrescent, lobes often with narrow purple line or spot at lobe base inside, outer surface bristly-hairy and stellate-puberulent, seldom densely glandular, multicellular hairs usually few or absent;

petals dark pink to deep purple, veins often paler, darker patch sometimes at base, 20–35 mm;

staminal column 4–6 mm, hairy;

anthers sessile on rim, white;

stigmas 5 or 6.

2 mm.

2 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.

6–7 mm diam.;

mericarps 5 or 6, sometimes pinkish when fresh, 2.5 mm, glabrous, back minutely hairy, back and sides reticulate-veined, back with prominent midvein, not pitted, mucro absent.
