Flora of North America species comparison

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

usually prostrate to ascending, sometimes trailing, sparsely stellate-hairy with simple hairs persistent on older stems.

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 triangular, 3–6 × 2.5 mm, papery;

petiole usually 2–5 times as long as blade, gradually reduced distally;

blade reniform to orbiculate-cordate, unlobed or very shallowly 5–7-lobed, 1.5–3.5(–6) × 1–4(–5) cm, base cordate, margins crenate-dentate, apex obtuse or rounded, surfaces glabrous or sparsely stellate-hairy.

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

axillary, 2–6-flowered fascicles, long-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.

1–5 cm, usually 10+ mm in fruit, several times longer than calyx, slender and flexible in fruit;

involucellar bractlets distinct, not adnate to calyx, linear to narrowly oblong-lanceolate, 3–5(–6) × 1 mm, shorter than calyx, margins entire, surfaces sparsely stellate-puberulent and short-ciliate.

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 4–7 mm, slightly accrescent, to 8 mm in fruit, lobes enclosing mericarps, not veined, triangular-ovate, stellate-hairy, ciliate;

petals pale lilac to whitish, drying pinkish or whitish, or faded, veins not darker, (6–)9–13 mm, length 2 times calyx, apex notched;

staminal column 4–4.5 mm, retrorsely stellate-puberulent;

style 12–15-branched;

stigmas 12–15 (same number as locules), purple.

1.5–2 mm.

1–1.5 mm.
