Flora of North America species comparison

single or in dense patches, erect, solid, hairy, hairs simple, spreading, bristly.

clustered, usually erect or ascending, sometimes proximally decumbent or prostrate, not rooting, solid, sparsely to densely appressed stellate-hairy.

cauline, evenly arrayed on stem;

stipules asymmetric-ovate and auriculate, 10–20 × 10–20 mm, width exceeding stem diam.;

petioles of proximal leaves 7–10 cm, gradually reduced distally to 2 cm, 1–1 1/2 times blade length proximally to 1/2 blade length distally;

blade ovate to elliptic, unlobed, usually (4–)7–8 × (2.5–)4–5 cm, reduced distally, base cordate, margins crenate-serrate, apex acute to rounded, surfaces glabrous abaxially, sparsely hirsute adaxially.

mostly basal, persistent, to 10+;

stipules linear-lanceolate to elliptic, 5–6 × 2 mm on proximal stem, 4–5 × 0.5 mm on distal stem;

petiole 5.5–16 cm, basal 3–5 times longer than blades, reduced distally to 1/2 times as long as blades;

blades: basal reniform-orbiculate, palmately (5–)7–9-lobed, deeply incised, (1.5–)2.5–4(–6) × (1.5–)2.5–4(–6) cm, base cordate, margins entire, apex rounded to acute, lobes linear to oblong, again deeply pinnately or ternately 3–5-lobed;

cauline ternately lobed, lobes linear to filiform, narrowest on distalmost leaves, somewhat fleshy, surfaces hairy, hairs appressed, stellate;

distalmost leaf lobes unlobed.

erect, capitate, ± dense, calyces overlapping, unbranched, 2–10-flowered, not elongate, not 1-sided, 3–5 cm;

proximalmost bracts involucrelike, similar to stipules in size and shape, narrowed to linear distally, usually divided to base, 10–20 mm, longer than pedicels, equaling or slightly shorter than calyx.

erect, open, calyces not conspicuously overlapping except sometimes in bud, usually unbranched, usually 3–9(–15)-flowered, elongate, 1-sided, to 7–25 cm;

bracts usually paired, linear or lanceolate to narrowly ovate, proximal divided to base, distalmost 2-fid or simple, 5 mm, shorter to longer than pedicels.

1–2 mm;

involucellar bractlets 3, 8–12 mm, equaling or longer than calyx.

3–8(–10) mm;

involucellar bractlets absent.

bisexual;

calyx 8 mm, sparsely to densely bristly, sometimes also stellate-hairy;

petals pink, usually pale-veined, 15 mm;

staminal column 4–6 mm, hairy;

anthers white;

stigmas 7 or 8.

usually bisexual or, infrequently, unisexual and pistillate, plants gynodioecious;

calyx (6–)7–10 mm, slightly enlarged in fruit, uniformly minutely stellate-puberulent;

petals pink to rose, pale-veined at least when dry, 9–20(–25) mm, pistillate shortest;

staminal column 3.3–7.5 mm, sparsely stellate-hairy;

anthers pale yellowish to white;

stigmas 6 or 7.

1.9 mm.

1.5–2 mm.

4–5 mm diam.;

mericarps 7 or 8, 2 mm, glabrous, smooth, back with medial line, mucro absent.

5–7 mm diam.;

mericarps 6 or 7, 3.5–4.3 mm, roughened, back finely glandular-puberulent, sides and back coarsely reticulate-veined, pitted, mucro 0.5–1 mm.
