Flora of North America species comparison

scattered, erect to ascending, base decumbent to erect, usually rooting freely, solid, proximally hairy or glabrate, hairs soft, simple and stellate, distally brittle, easily broken, glabrous-glaucous.

single, erect, unbranched or distally branched, often zigzag, solid, proximally usually glabrous or sparsely stellate-puberulent.

mostly basal or cauline 3 or 4 on proximal 1/3 of stem, much reduced;

stipules wide-lanceolate to ovate, 3–4 × 1–1.5 mm;

petioles of proximal leaves 6–12 cm, 2–4 times as long as blades in basal leaves, those of cauline leaves greatly reduced to 1/2 times or as long as blades;

blade rounded to reniform, palmately (3–)5–7-lobed, usually (1–)2–5(–10) × (1–)2–5(–10) cm, apex rounded, surfaces: abaxial harshly stellate-hairy, adaxial usually simple-haired, basal blades shallowly incised, lobes with 3 deep crenations;

cauline blades usually deeply 3–5(–7)-lobed nearly to base, lobe margins dentate or entire.

cauline;

stipules deciduous or inconspicuous, sometimes purplish, subulate, 1–1.5(–3) × 0.5–1 mm;

petiole 0.5–1.5(–3) cm, usually 1/2 times involucellar bractlets absent.

ascending, open, calyces not conspicuously overlapping except sometimes in bud, unbranched or few-branched, loosely (3–)5–10(–20)-flowered, not greatly elongated, 1-sided, 10–20 cm;

bracts narrowly elliptic, shallowly 2-fid, proximal bracts divided to base and often with leaf remnant between, 3–4 mm, usually shorter than to equaling pedicels.

3–4(–10) mm;

involucellar bractlets absent.

bisexual or unisexual and pistillate, plants gynodioecious;

calyx 7–10 mm, slightly enlarged in fruit, uniformly, coarsely stellate-puberulent (some rays sometimes longer than others);

petals dark pink, pale-veined at least when dry, pistillate 10–15(–20) mm, bisexual 20–25(–33) mm;

staminal column 4–5 mm, sparsely hairy;

anthers white to pale pink;

stigmas 6 or 7(or 8).

bisexual or unisexual and pistillate, plants gynodioecious;

calyx 8–10(–12) mm, not much enlarging in fruit, stellate-canescent, sparsely ciliate;

petals pink to rose-purple or white, pale-veined, often whitened at base, 18–20(–25) mm;

stamens: outer filaments incompletely connate, distally distinct, anthers not attached to connate portion of filaments;

staminal column 6–7 mm, hairy;

anthers white, stalked, aborted in pistillate flowers;

stigmas 6 or 7.

2 mm.

1.5–2 mm.

6–7 mm diam.;

mericarps 6 or 7(or 8), 3–3.5 mm, back not ribbed, roughened, sides and back strongly reticulate-veined-rugose and pitted (honeycomblike), top minutely glandular-puberulent, mucro 0.8–1 mm.

5–7 mm diam.;

mericarps 6 or 7, 2.5–4 mm, sides smooth, margins rugose, back reticulate-veined, deeply pitted especially on top, glabrous or glandular-puberulent, mucro 0.5–0.8(–1) mm.
