Flora of North America species comparison

single, erect, usually branched distally, solid, both short-stellate-puberulent and long soft bristly-hairy, hairs erect.

1–20, clustered, erect to ascending or decumbent, usually not rooting, solid, proximally hairy, hairs simple, stellate, or mixed, 0.5–1.5 mm, distally usually stellate-hairy or glabrous.

basal, early-deciduous, and cauline;

mid to distal stem stipules divided into 2–5 filiform or linear segments, involucrelike, 10+ × 1 mm;

petiole (4–)6–20(–50) cm, usually 1/2 times to as long as blade;

basal leaf blades orbiculate, unlobed, 1–2.5 × 1–2.5 cm, base cordate, margins crenate, apex rounded;

cauline leaf blades orbiculate, palmately 5–7-lobed, (1–)2–6 × (1–)2–6 cm, lobes linear distally, sometimes 3-toothed or -lobed, then midtooth or lobe much longer than laterals, margins entire, surfaces bristly-puberulent.

mostly basal, cauline to 5, (plant sometimes scapose);

stipules linear to lanceolate, 2–8 × 1–1.5 mm;

petioles of basal leaves 5–10(–25) cm, often 5 times blade length, distally reduced to 1/2 times blade length;

blade orbiculate to reniform, 2–6(–8) × 2–6(–8) cm, base cordate, apex rounded, surfaces stellate-hairy abaxially, moderately minutely stellate-hairy to appressed-hairy adaxially, basal leaves usually shallowly 7-lobed, sometimes unlobed and margins crenate, cauline smaller, palmately 3–5-lobed ± to base, lobe margins entire or incised.

erect, dense, calyces overlapping, occasionally short-branched, clusters to 10-flowered, subumbellate to elongate in age, not 1-sided;

bracts linear or filiform, palmately 2–7-lobed, 8–12 mm, lobes linear, usually becoming involucrelike, 1–2.5 cm, subequal to or longer than calyx.

usually ascending, ± open, calyces not conspicuously overlapping except sometimes in bud, branched or unbranched, 10+-flowered, most flowers spaced 1+ cm apart, elongated, extending well above leaves, narrow, often 1-sided, (15–)30–45 cm;

bracts lanceolate, mostly 2-fid, proximal bracts divided ± to base, distal sometimes undivided.

1–3 mm, (short branches may easily be mistaken for pedicels);

involucellar bractlets absent.

2–8(–15) mm;

involucellar bractlets absent.

bisexual;

calyx 8–12 mm, not much accrescent, lobes often with narrow purple line or spot at lobe base inside, outer surface bristly-hairy and stellate-puberulent, seldom densely glandular, multicellular hairs usually few or absent;

petals dark pink to deep purple, veins often paler, darker patch sometimes at base, 20–35 mm;

staminal column 4–6 mm, hairy;

anthers sessile on rim, white;

stigmas 5 or 6.

bisexual or unisexual and pistillate, plants gynodioecious;

calyx 6–10 mm, densely to sparsely stellate-puberulent, hairs usually longer, coarser, 2–4-rayed especially at margins and over veins;

petals pinkish rose to pinkish lavender or magenta, pale-veined or not, base often white, 10–25 mm, pistillate darker, 6–15 mm, bisexual 12–25(–30) mm;

staminal column 5–6 mm, puberulent;

anthers white;

stigmas (6 or)7–9.

2 mm.

2.5 mm.

6–7 mm diam.;

mericarps 5 or 6, sometimes pinkish when fresh, 2.5 mm, glabrous, back minutely hairy, back and sides reticulate-veined, back with prominent midvein, not pitted, mucro absent.

5–6 mm diam.;

mericarps (6 or)7–9, 2.5–3 mm, roughened, glandular-puberulent, lightly to moderately reticulate-veined, pitted, mucro 0.5–1 mm.
