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.

1–3, clustered, erect, solid, proximally hairy, hairs a mix of soft, appressed, stellate and/or longer, bristlelike, 2 mm, distally sparsely puberulent.

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;

stipules deciduous, lanceolate, 4–7(–15) × 1–2 mm;

petioles of proximal leaves 10–20 cm, 3–4 times as long as blades, reduced distally to 1/2 times blade length;

blades: proximal orbiculate, shallowly or deeply 5–9-lobed, 5–10 × 5–10 cm, base wide-cordate to ± truncate, lobe margins coarsely crenate and dentate, apex 2–5-toothed, mid stem largest, 5–7(–9)-lobed, usually incised ± to base, 10–25 × 10–25 cm, lobe margins coarsely dentate to laciniate or entire, surfaces scabrid-hairy, hairs simple or forked, stiff;

distalmost 5–7-lobed, lobes linear, subentire, margins ciliate, surfaces glabrescent or with few hairs on abaxial veins.

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, spiciform or subcapitate, dense, calyces usually conspicuously overlapping in flower and sometimes in fruit, branched, ca. 10-flowered, flowers/calyces overlapping, not 1-sided, 3–7(–10) cm, elongated in fruit;

bracts lanceolate-elliptic, undivided, 3–8 mm, longer than pedicels, often longer than young flower buds, ± equaling calyx.

1–2(–5) mm;

involucellar bractlets absent.

1–2 mm, to 4 mm 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 unisexual and pistillate, plants gynodioecious;

calyx 5–9 mm, to 10 mm in fruit, margins ciliate, minutely stellate-puberulent and bristly with longer, coarser, usually pustulate hairs usually on pads, bristle hairs 1–2 mm;

petals pink to pinkish lavender, not notably whitish- or pale-veined, (5–)8–30 mm, pistillate 5–15 mm, bisexual to 20–30 mm;

staminal column 5–7 mm, hairy;

anthers white to pale pink;

stigmas (6 or)7 or 8.

2 mm.

1.8 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 (6 or)7 or 8, 2.5 mm, sparsely glandular-puberulent, margins usually sharp-edged but not winged, sides coarsely reticulate-veined to nearly smooth, back lightly reticulate-veined, usually prominently roughened at least on margins and/or back, pitted, mucro 0.5 mm.
