erect or ascending, glabrous or sparsely hairy, hairs both simple and stellate.

procumbent or trailing to ascending, villous-hirsute.

stipules persistent, lanceolate to ovate-triangular, 3–5(–8) × 3 mm;

petiole 1/2 to 1 1/2 times as long as blade, pubescent in adaxial groove, otherwise glabrous;

blade reniform to suborbiculate-cordate, unlobed or shallowly 3–7-lobed, sinuses to 1/2 to base, (2–)5–10(–14) × (2–)5–10(–14) cm, base cordate to ± truncate, lobes semicircular to oblong, margins crenate, apex rounded to wide-acute, surfaces glabrous or sparsely hairy, hairs simple or stellate.

stipules persistent, ovate to broadly ovate, 4–6 × 3–5 mm;

petiole 2–5 times as long as blade;

blade semicircular or reniform, 2–4 × 2–4 cm, sometimes to 12 cm in young plants, base cordate to nearly truncate, distalmost leaves sometimes wide-cuneate, margins crenate or dentate, undulate, or with 5–7 shallow, lobes, apex obtuse, rounded, or acute, surfaces sparsely hairy, hairs simple.

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

stellate;

petals pink to lavender, drying bluish, usually with darker veins, 5–15 mm, subequal to or length slightly less than 2 times calyx, glabrous or nearly so;

style 7–10-branched;

stigmas 7–10.

1–2.5 cm, 1–4.5 cm in fruit, much longer than calyx, glabrous or sparsely stellate-hairy;

involucellar bractlets distinct, sometimes adnate to calyx in basal 1 mm, oblong-lanceolate to elliptic or narrowly obovate, reticulate-veined, (3–)4–5(–7) × 2.5–4 mm, shorter than calyx, margins entire, surfaces glabrous, sparsely ciliate.

calyx reticulate-veined, 5–6 mm, to 10 mm in fruit, lobes incompletely enclosing mericarps, stellate-puberulent;

petals pink to purple or reddish purple with darker veins, usually drying blue, (12–)16–30(–45) mm, length 2 1/2–3(–4) times calyx;
