Flora of North America species comparison

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

several to many (ca. 3–20+), clustered, erect to ascending, branched or unbranched, solid, usually densely stellate-canescent.

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.

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

stipules linear-lanceolate to ovate, 2–9 × 1–3 mm, widest above base, width sometimes exceeding stem diam.;

petiole 0.6–3(–9) cm, 1/2–3 times as long as blade, apex often with pulvinus;

blade orbiculate or reniform to flabelliform, unlobed and margins coarsely crenate to shallowly or deeply lobed, 1–7 × 1–7 cm, usually wider than long, base truncate or cordate, apex rounded, surfaces stellate-hairy.

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.

erect, infrequently ascending, usually spiciform, dense or open, calyces overlapping or not, branched or unbranched, 2–20+-flowered, proximal flowers scattered, usually more congested distally, not notably elongate in flower, not 1-sided, (1.5–)3–25 cm, usually longer in fruit;

bracts linear to ovate-lanceolate or oblong, undivided, 2-fid, or divided, 2–8(–12) mm, not involucrelike, distal entire to 2-fid, stipulelike, proximalmost not involucrelike, divided to base, much shorter than to nearly equaling calyx.

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

involucellar bractlets absent.

1–4(–5) mm;

involucellar bractlets (2 or)3, 2–10 mm, shorter to slightly longer than calyx.

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.

usually bisexual, infrequently unisexual and pistillate;

calyx 4–12 mm, densely to sparsely stellate-puberulent to long-bristly;

petals usually pale pink to pink-lavender, rarely white, veins not conspicuously whitened, 5–17 mm;

staminal column 4–7 mm, hairy;

anthers white to pale pinkish or pale yellow;

stigmas (4–)6 or 7(–10).

2 mm.

1–2 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.

4–7 mm diam.;

mericarps usually (4–)6 or 7(–10), (1.5–)2–2.5 mm, glabrous, sides usually smooth, thin, margins and back usually lightly reticulate-veined, transversely corrugated, back usually with medial, raised line, not pitted, mucro absent.
