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

stipules deciduous, ovate, 4–5 × 2–3 mm, papery, apex acute to obtuse, sparsely stellate-hairy and ciliate;

petiole longer than blade;

blade rounded, shallowly and unequally 5–7(–9)-lobed (lobes obtuse), 5–20 × 5–20 cm, base cordate, margins crenate, apex obtuse to rounded, surfaces densely soft stellate-hairy especially abaxially.

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 in fascicles.

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

involucellar bractlets connate in proximal 1/3, adnate to calyx, lobes broadly ovate to round, 8 × 5–6 mm, longer than calyx, margins entire, apex acute or obtuse, surfaces stellate-hairy.

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 mm, not much enlarged in fruit, densely stellate-canescent;

petals rose to lavender with 5 darker veins, dark purple basally, 15–20 mm, length 4–5 times calyx, apex emarginate;
