Flora of North America species comparison

usually erect or ascending, rarely decumbent, wide-branched, glabrous or sparsely stellate-hairy distally.

trailing to ascending, hairs usually both simple and stellate.

stipules persistent, broadly lanceolate, 4–5 × 2–3 mm;

petiole 2–3(–4) times as long as blade;

blade suborbiculate-cordate or reniform, mostly shallowly 5–7-lobed or angled, 2–8(–10) × 2–8(–10) cm, base cordate (to nearly truncate), lobes deltate or rounded, margins evenly crenate, apex rounded to broadly acute, surfaces glabrous or hairy, especially at base, hairs simple and stellate.

stipules persistent, narrowly to ovate-triangular, 3–5(–6) × 2–3 mm;

petiole on proximal and midstem leaves to 3 times as long as blade, usually 2 times longer on distal leaves, sparsely hairy, hairs simple and stellate;

blade cordate to broadly reniform, unlobed or broadly and very shallowly 5-lobed, 1–5 × 1–5 cm, base cordate, margins finely crenate or dentate, apex rounded, surfaces glabrous or sparsely stellate-hairy.

axillary, flowers solitary or in 2–4-flowered fascicles.

axillary, flowers solitary or in 2–10-flowered fascicles (compact cymes), obviously stalked.

0.2–0.4 cm, usually to 1 cm in fruit, shorter than calyx;

involucellar bractlets distinct, not adnate to calyx, linear to filiform, (1–)2–3 × 0.3 mm, shorter than calyx, margins entire, surfaces glabrous or slightly ciliate.

0.4–0.5 cm, to 1–2.4 cm in fruit, slender and flexible, sparsely hairy, hairs simple and stellate;

involucellar bractlets distinct, not adnate to calyx, linear to lanceolate, 3–4 × 0.5 mm, shorter than calyx, margins entire, surfaces sparsely ciliate and stellate-puberulent.

calyx 3–4.5 mm, to 7–8 mm in fruit, glabrous or stellate-hairy, lobes wide-spreading outward in fruit, orbiculate-deltate, reticulate-veined, apex often abruptly acuminate, short-ciliate or not, scarious in fruit;

petals white to pale lilac, drying pinkish or whitish, or faded, veins not darker, 3–4.5(–5) mm, subequal to or only slightly longer than calyx, glabrous;

staminal column 1.5 mm, glabrous;

style 10- or 11-branched;

stigmas 10 or 11.

calyx 3–5 mm, 5–6 mm in fruit, lobes incompletely enclosing mericarps, mostly hispid, hairs both simple and stellate, conspicuously long-ciliate, lobes not obviously veined;

petals pale pink or nearly white, drying pinkish or whitish, or faded, veins not darker, 3–6 mm, subequal to slightly longer than calyx;

staminal column 1–1.5 mm, glabrous;

style 10- or 11-branched;

stigmas 10 or 11.
