clustered, erect, solid, bristly-hirsute, hairs simple, forked, and stellate.

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.

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

stipules linear-lanceolate, 5–15 × 0.5 mm;

petioles 4–7 cm on distal leaves, 1/2 times to as long as blades, longer on proximal leaves;

blade maplelike, usually palmately (3–)5–7- 7–15 mm, pistillate 6–7 mm, bisexual or staminate 10–12 mm;

staminal column 5–7 mm, hairy;

anthers white to pale purplish or pale yellowish;

stigmas 5–9.

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.

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.

2–8(–15) mm;

involucellar bractlets absent.

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.

1–1.5 mm.

2.5 mm.

5–6 mm diam.;

mericarps 5–9, 2.5 mm, glabrous or sparsely stellate-hairy, margins rounded, back ridged, sides smooth or with slight corrugations near margins, 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.
