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 few to many, clustered, sprawling or decumbent to ascending, rarely erect, not rooting, solid, glaucous, proximally usually stellate-puberulent, sometimes glabrous, distally 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.

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, 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.

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.

2–3(–10) mm;

involucellar bractlets absent.

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.

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.

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.
