Flora of North America species comparison

clustered, erect, base decumbent-ascending, solid or ± hollow in age, usually ± glaucous distally, glabrous or sparsely hirtellous, hairs short, appressed, simple.

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

basal and cauline;

stipules sometimes deciduous, lanceolate to ovate, (4–)7–9(–14) × (1.2–)3–4 mm;

petioles of proximal leaves 18–37 cm, 3–5 times as long as blades, distal 5–20 cm, to 1/2–1 times as long as blades;

blades: basal reniform to rounded, unlobed and marginally deeply crenate or very shallowly palmately 5–7-lobed, 6–20 × 6–20 cm, base cordate, apex rounded;

cauline deeply 5–9-lobed, lobes linear-elliptic to oblong-elliptic, margins usually entire, sometimes toothed, surfaces finely, sparsely hairy, hairs mostly simple.

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.

erect, spiciform, proximally open, distally dense, otherwise calyces not conspicuously overlapping except sometimes in bud, branched, 20+-flowered, proximalmost flowers spaced usually to 1 cm apart, not leafy-bracted, elongate, not 1-sided, 10–20 cm;

bracts single, purple, mm, hairy;

anthers white;

stigmas (6 or)7 or 8.

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.

1–2(–5) mm;

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.

1.5 mm.

2 mm.

4–5 mm diam.;

mericarps (6 or)7 or 8, 2 mm, roughened, sparsely glandular-puberulent apically, sides finely reticulate to faintly rugose, sometimes also on back, to nearly smooth, not pitted, mucro 0.5–1 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.
