Flora of North America species comparison

several to many (ca. 3–20+), clustered, erect to ascending, branched or unbranched, solid, usually densely stellate-canescent.

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.

cauline, evenly arrayed on stem, usually similar in size, shape;

stipules linear-lanceolate to ovate, 2–9 × 1–3 mm, widest above base, width sometimes exceeding stem diam.;

petiole 0.6–3(–9) cm, 1/2–3 times as long as blade, apex often with pulvinus;

blade orbiculate or reniform to flabelliform, unlobed and margins coarsely crenate to shallowly or deeply lobed, 1–7 × 1–7 cm, usually wider than long, base truncate or cordate, apex rounded, surfaces stellate-hairy.

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.

erect, infrequently ascending, usually spiciform, dense or open, calyces overlapping or not, branched or unbranched, 2–20+-flowered, proximal flowers scattered, usually more congested distally, not notably elongate in flower, not 1-sided, (1.5–)3–25 cm, usually longer in fruit;

bracts linear to ovate-lanceolate or oblong, undivided, 2-fid, or divided, 2–8(–12) mm, not involucrelike, distal entire to 2-fid, stipulelike, proximalmost not involucrelike, divided to base, much shorter than to nearly equaling calyx.

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.

1–4(–5) mm;

involucellar bractlets (2 or)3, 2–10 mm, shorter to slightly longer than calyx.

3–4(–10) mm;

involucellar bractlets absent.

usually bisexual, infrequently unisexual and pistillate;

calyx 4–12 mm, densely to sparsely stellate-puberulent to long-bristly;

petals usually pale pink to pink-lavender, rarely white, veins not conspicuously whitened, 5–17 mm;

staminal column 4–7 mm, hairy;

anthers white to pale pinkish or pale yellow;

stigmas (4–)6 or 7(–10).

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).

1–2 mm.

2 mm.

4–7 mm diam.;

mericarps usually (4–)6 or 7(–10), (1.5–)2–2.5 mm, glabrous, sides usually smooth, thin, margins and back usually lightly reticulate-veined, transversely corrugated, back usually with medial, raised line, not pitted, mucro absent.

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.
