Many-stemmed perennial herb, stems of indeterminate length, either clumped or straggling up through other vegetation, pilose with long (up to 3-25 mm) delicate spreading hairs, a few of them gland-tipped. Stipules deeply dissected, the segments linear-acuminate. Leaves with petioles mostly 50-270 mm long, pilose as the stem; blade up to 110 mm in diam., peltate, deeply divided into 5 lobes (ratio 3-4.3:1 measured on the centre lobe), lobes oblong-elliptic in outline with usually 3 coarse sharp teeth on either side, thinly pilose above with coarse appressed hairs, more densely so below with long spreading hairs. Peduncles opposite the upper leaves and terminal, forming spreading cymes, usually 2-flowered, ±27-100 mm long, densely pilose with spreading glandular and eglandular hairs underlain by fine short curly ones. Pedicels ±7-18 mm long, hairy as the peduncles. Sepals ±6-7 x 3.5 mm, glandular-pilose underlain by very short fine appressed hairs. Petals ±10-13 x 7.5-8 mm, obovate, pink. Rostrum with spreading gland-tipped hairs.
