Flora of North America species comparison

usually single, erect and sometimes supported by adjacent plants (sprawling), base prostrate or decumbent-ascending to erect, often rooting, solid, not brittle, sometimes ± glaucous distally, proximally stellate-hairy, glabrate, hairs minute or larger and coarse (never simple only), usually 4-rayed, 0.5–1 mm.

scattered, ascending-decumbent or creeping, freely rooting, solid, flowering stems ascending to erect, proximal and midstem densely spreading-long-hirsute, bristles 2–3 mm, often on swollen pads, rarely subglabrous, base without stellate hairs, distally somewhat stellate-puberulent.

basal and/or cauline, similar in size and shape;

stipules linear to lanceolate, 2–3 × 1.1 mm;

petiole (1–)5–10(–15) cm, longest on proximal leaves, 1–4 times longer on proximal leaves to 1/2 times to as long as blade on distal leaves;

blade usually shallowly to deeply palmately 3–7-lobed usually halfway to base, proximal and distal cauline blades rounded to reniform, 2–3 × 2–5 cm, usually wider than long, base cordate to truncate, margins crenate, apex blunt or rounded, lobes narrowest at base, margins usually apically coarsely toothed, rarely entire, surfaces stellate-puberulent.

basal and cauline;

stipules on prostrate stems wide-lanceolate to ovate, 5–7 × 2–5 mm, elsewhere 3–6 × 1.3–2 mm;

petiole 3–8(–15) cm, longest on basal leaves, proximalmost 3 times blade length, reduced distally;

blades: proximalmost suborbiculate, unlobed or very shallowly lobed, 2.5–5 × 2.5–5 cm, base wide-cordate, margins deeply crenate, apex rounded, surfaces usually bristly, hairs long, simple, to subglabrous, not stellate-hairy;

distal rather similar to proximalmost or more deeply palmately 3–5(–7)-lobed or toothed, lobes simple or 3-dentate.

ascending or erect, often spiciform, open, calyces not overlapping in flower or fruit, unbranched or branched, 2–15(–30)-flowered, elongate in both flower and fruit, usually 1-sided, 6–11(–30) cm;

bracts leaflike to linear, usually 2-fid, (2–)3–5(–15) mm.

erect, open or some flowers overlapping, calyces not conspicuously overlapping except sometimes in bud, unbranched, usually 2–10-flowered, flowers 1+ cm apart, not much elongated, usually 1-sided, (5–)10–20 cm;

bracts linear or narrowly oblong-lanceolate, 2-fid, usually inrolled, proximal separated to base, 2–4 mm, usually equaling or slightly longer than pedicels, much shorter than calyx.

2–5(–10) mm;

involucellar bractlets absent.

2–5 mm;

involucellar bractlets absent.

bisexual or unisexual and pistillate, plants gynodioecious;

calyx 5–12 mm, uniformly densely stellate-puberulent;

petals pink to pale purple, pale-veined, (5–)10–28 mm, pistillate flowers darker, 5–15 mm;

staminal column 4–5 mm, stellate-puberulent;

anthers white;

stigmas (6 or)7 or 8.

bisexual;

calyx (6.5–)8–10 mm, somewhat accrescent, stellate-puberulent, marginal hairs longer, sometimes few glandular, multicellular, lobes sometimes dull purplish at tips;

petals dark pink to pale lavender-pink, usually pale-veined, 12–20 mm;

staminal column 6–7 mm, minutely hirtellous;

anthers white;

stigmas (6–)8–10.

1.5–2.8 mm.

1.5–2 mm.

6–8 mm diam.;

mericarps (6 or)7 or 8, 3–4 mm, usually glandular-puberulent to stellate-puberulent, sometimes glabrous, roughened, strongly reticulate-veined, sides and back pitted, mucro 0.5–1 mm.

6 mm diam.;

mericarps (6–)8–10, 3 mm, roughened, top, back, mucro densely stellate-puberulent, deeply reticulate-veined, pitted, mucro 1 mm.
