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, scattered, erect, usually purple tinted proximally, hollow especially towards base, pithy distally, 10–14 mm diam. just distal to base, often glaucous, proximally densely retrorsely bristly-hairy and stellate-hairy, hairs pustulate, 1.5–2.5 mm, distally sometimes 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.

mostly cauline, basal usually absent;

stipules deciduous, with pink band on stem at base, narrowly lanceolate, (3.5–)5(–8) × 0.7(–1.5) mm;

petioles of proximal leaves 6–8 cm, those of midstem leaves 10–14 cm, 2 times to as long as blade, apex curved with swollen portion or pulvinus 5–6 × 1.8 mm;

blades of proximalmost cauline leaves rounded, shallowly, palmately 4- or 5-lobed, 0.5–0.7 × 0.5–0.7 cm, lobe margins irregularly, sparsely dentate, apices rounded, mid-cauline blades 5–7-lobed, 6.5–12 × 10–13 cm, wider than long, gradually reduced distally, lobes straplike, divided 3/4 to base, lobes 5.5 × 1.5–1.8 cm, margins coarsely dentate, surfaces sparsely, minutely hispid and stellate-puberulent, distal leaves deeply 5-lobed, otherwise similar in shape, leaves immediately below inflorescence greatly reduced, irregularly 2- or 3-lobed.

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, open, calyces usually not overlapping, usually branched, branches 14–18 cm, each branch 10–20 flowered, not 1-sided, elongate, 5–20 cm;

bracts 1, usually undivided, narrowly lanceolate, often 2-fid, 2.5 mm, equaling or slightly longer than pedicel, much shorter than calyx.

1–2(–5) mm;

involucellar bractlets absent.

2–3(–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.

bisexual or unisexual and pistillate, plants gynodioecious;

calyx 5–6 mm, to 8 mm in fruit, uniformly, densely stellate-puberulent, surface obscured;

petals pale pink, pale-veined, pistillate 7–9 mm, bisexual (10–)14–20(–25) mm;

staminal column 6–8 mm, stellate-puberulent;

anthers white to cream or pale yellow;

stigmas (6)7 or 8.

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.

6–7 mm diam.;

mericarps (6)7 or 8, sides 3 mm, thick, back and margins thick, rounded, reticulate-veined, pitted, back with prominent groove, top sparsely glandular-stellate-puberulent, mucro 1 mm.
