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.

single or clustered, erect, rarely rooting at base, unbranched or distally branched, proximally usually solid, sometimes hollow in age, base glabrous, coarsely stellate-hairy to long-bristly, or glabrate, hairs usually becoming appressed, simple or stellate.

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, basal sometimes deciduous, cauline 3+;

stipules usually deciduous, linear to lanceolate, 4–6(–14) × 0.5–1(–2) mm;

petioles of basal and proximal leaves (5–)7–10(–35) cm, 3–5 times as long as blades, reduced distally, distalmost leaves sometimes subsessile;

blade cordate or reniform-orbiculate, 3–10(–15) × 3–10(–15) cm, base cordate, apex rounded, lobe apex often acute, surfaces glabrous or sparsely hairy, hairs minute, simple, forked, or stellate, proximal usually shallowly palmately 5–7(–9)-lobed, sometimes unlobed with margins crenate;

midstem more deeply (3–)5–9-lobed, lobes again palmately or pinnately lobed, distalmost unlobed or 3(–5)-lobed, segments unlobed or deeply lobed, narrow.

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, usually spiciform, sometimes subcapitate, congested in bud, dense, calyces sometimes conspicuously overlapping in flower and sometimes in fruit, to open and elongate, few-branched or unbranched, 10–20+-flowered, flowers opening and closing sequentially from base to apex, sometimes 3–10 open on same day, not leafy-bracted, not 1-sided, (1.5–)10–30 cm, elongating in flower or fruit;

bracts linear to linear-lanceolate, undivided to 2-fid, proximal sometimes divided to base, 4–6(–7) mm, sometimes exceeding flower buds, usually equaling or longer than pedicels, shorter than calyx.

2–5(–10) mm;

involucellar bractlets absent.

1–3(–10) 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 or unisexual and pistillate, plants gynodioecious;

calyx usually green, 3.5–10 mm, usually lightly reticulate-veined, glabrous or densely, uniformly stellate-puberulent or bristly, surface often obscured;

petals usually overlapping, pink or pink-lavender to dark rose-pink or magenta, not notably pale-veined, pistillate 5–10 mm, bisexual 8–15(–20) mm;

staminal column 4–6(–9) mm, hairy;

anthers white to pinkish;

stigmas 6–9.

1.5–2.5 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.

4–7 mm diam.;

mericarps 6–9, 2–3 mm, sparsely glandular-puberulent, sometimes glabrous, not stellate-hairy, back and margins rounded, smooth or slightly reticulate-veined or pitted, infrequently prominently roughened at least on margins and/or back, mucro 0.1–0.7 mm.
