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

erect, usually stellate-hairy.

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.

stipules persistent, ovate-triangular, slightly falcate, 4–7 × (2–)4–5 mm, usually papery;

petiole shorter than to equaling or longer than blade, surfaces often glabrate abaxially, stellate-hairy adaxially;

blade round to broadly reniform, unlobed or broadly, shallowly 5–7-lobed, 3–10(–25) × (2–)5–10(–25) cm, base cordate or sometimes ± not adnate to calyx, linear to lanceolate, reticulate-veined, 2–3 × 0.5 mm, to 6 × 1 mm in fruit, shorter than calyx, thin and translucent, margins entire, sparsely stellate-puberulent and ciliate.

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

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 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;
