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.

usually few to many, clustered, sprawling or decumbent to ascending, rarely erect, not rooting, solid, glaucous, proximally usually stellate-puberulent, sometimes glabrous, distally 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, basal leaves 9 or fewer or deciduous;

stipules lanceolate, (2–)3–5(–6) × 0.5–1.5 mm;

petioles of basal and proximal cauline leaves 6–14 cm, 3–4 times as long as blades, reduced distally to 1/2 times to as long as blades;

blade reniform-orbiculate, palmately 5(–7)-lobed, deeply incised, 2–6(–8) × 2–6(–8) cm, glaucous, surfaces glabrous or minutely stellate-puberulent, lobes shallowly dentate, more deeply divided on distal leaves, margins entire, distalmost sometimes linear, unlobed.

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.

ascending, open, calyces not conspicuously overlapping except sometimes in bud, usually unbranched, 3–10(–20)-flowered, elongate, 1-sided, 8–20 cm, axis curved between flowers, sometimes zigzag in appearance;

bracts linear to lanceolate, distinct or connate and 2-fid, 5 mm, proximal divided to base, distal often undivided, shorter than to equaling pedicels.

1–2(–5) mm;

involucellar bractlets absent.

2–3(–10) 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.

bisexual or unisexual and pistillate, plants gynodioecious;

calyx 5–10 mm, enlarging in fruit, hairy, hairs scattered, minute, stellate and sometimes capitate, glandular;

petals pink to pink-purple, pale-veined at least when dry, pistillate (7–)9–12 mm, bisexual 15–20(–25) mm;

staminal column 4–7 mm, stellate-hairy;

anthers pale yellow or pinkish to white;

stigmas 6–8.

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.

5–7 mm diam.;

mericarps 6–8, 3–3.5 mm, roughened, sides reticulate-veined and deeply pitted, back reticulate-veined and glandular-puberulent, mucro 0.3–1 mm.
