Diagnostic Description

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).

    Morphology

    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.
