Flora of North America species comparison

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

often single, usually scattered, erect, usually unbranched, solid or somewhat hollow in age, proximally densely, finely stellate-hairy, hairs spreading, distally glaucous, glabrous.

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.

cauline, mostly on abaxially, bristly-hirsute adaxially.

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, loosely 10+-flowered, flowers 1+ cm apart, elongate, sometimes 1-sided, 30–40(–45) cm;

bracts inconspicuous, lanceolate to linear, distal unlobed, 2–4 mm, proximal divided ± to base, 4–6 mm, usually equaling or shorter than pedicels.

1–2 mm;

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

2–5 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, sometimes pistillate, plants gynodioecious;

calyx 10–15 mm, uniformly, densely stellate-puberulent;

petals: bisexual pale pink, often drying yellowish, pale-veined or not, base pale pink to white, (15–)20–35 mm, pistillate usually darker purple, base white, 5(–10) mm;

staminal column 6–8 mm, hairy;

anthers white;

stigmas (6 or)7 or 8.

1.9 mm.

2–2.5 mm.

4–5 mm diam.;

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

6–8 mm diam.;

mericarps (6 or)7 or 8, 3–3.5 mm, usually glabrous or very sparsely glandular-puberulent, distinctly narrowly wing-margined dorsally, sides lightly reticulate-veined, pitted, back less so, mucro 0.3–0.5 mm.
