It is allied to the widespread G. schlechteri, but differs in its more deeply cut leaves (the free part of the midlobe in proportion to the joined part being about 8-16:1, not 2-5:1); it is also markedly less glandular than G. schlechteri; and when gland-tipped hairs are present, they are very short (up to ±0.3 mm, not mostly 0.5-1.5 mm).
Diffuse perennial herb, stems straggling, of indeterminate length, loosely branched, pubescent, most hairs short (less than 0.3 mm), fine, ± retrorse, or spreading, occasionally some gland-tipped, fewer long acute or gland-tipped hairs also sometimes present. Stipules deeply dissected, segments linear-acuminate. Leaves with petioles up to 80 mm long, diminishing upwards, uppermost leaves subsessile, pubescent with short fine ± retrorse and curled hairs, a few longer glandular or eglandular spreading hairs also sometimes present; blade up to ±65 mm in diam., digitately 5-lobed to within 2-3 mm of the base, (ratio 8-16:1 measured on the median lobe), lobes elliptic in outline, lobed and toothed, sparse short fine appressed hairs above, pubescent mainly on the veins and margins below, these hairs ± spreading. Peduncles opposite the upper leaves and not always exceeding them, 1- or 2-flowered, pubescent with fine ± retrorse hairs and sometimes very short (up to 0.3 mm) spreading gland-tipped ones as well. Pedicels up to 25 mm long, hairy as the peduncles. Sepals ±4.5-5 x 1.75-2.5 mm, excluding mucro, appressed pubescent, a few longer spreading gland-tipped hairs also sometimes present. Petals ±11 x 7 mm, obovate, apex scarcely notched, 'mauve' (Moll). Rostrum pubescent, a few of the hairs sometimes gland-tipped. Can probably be found in flower between December and March.
