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.

erect, sometimes supported by other vegetation, sometimes proximally decumbent and often rooting to erect, roughly minutely- or long-stellate-hairy, hairs spreading, usually on swollen bases, minutely hairy to glabrate distally.

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.

mostly cauline, evenly distributed, not concentrated at stem base, gradually reduced distally;

petiole (1–)5–10(–15) cm, those of proximal leaves 4 times as long as blade, reduced distally to 1/2 times to as long as blade;

blades: proximal usually lobed, distal palmately (5–)7-lobed, (3–)5–12(–15) cm wide, base with wide sinus to truncate, margins crenate-serrate, lobe tips oblong, usually 3-toothed (sometimes entire), distalmost 3–5-parted;

surfaces stellate-puberulent, sometimes with some simple hairs.

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, unbranched or branched, 8–15(–30)-flowered, sometimes 1-sided;

proximalmost bract usually leaflike, 15 × 12 mm, distal bracts linear, 3 mm, shorter than pedicel.

2–5(–10) mm;

involucellar bractlets absent.

2–5(–10) mm.

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.

calyx 5–7 mm, to 7–10 mm in fruit;

petals pink to pale purple, pistillate usually (5–)10–15 mm, bisexual (15–)20–25 mm;

stigmas (6 or)7 or 8.

1.5–2.8 mm.

1.5 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.

6–8 mm diam.;

mericarps (6 or)7 or 8, 3–4 mm; prominently reticulate-veined, pitted, margins and back rugose-pitted but less so on back, sometimes glabrous, mucro 0.5–0.8 mm.
