Perennial 30-60 cm tall, glandular-villous. Rootstock with 1-2 ± ovoid tubers. Stem erect, striate, retrorsely pubescent-villous. Leaves 30-35 mm broad, orbicular to sub-reniform, palmatisect into 5-7 segments; segments pinnatipartite or-fid unequally into acute-obtuse lobes, appressed hairy. Stipules 2 mm long, ovate, sub-acuminate, pubescent; petiole 1-3 cm long, those of basal leaves up to 2.5 cm long, glandular. Peduncles 2-flowered. Flowers 13-15 mm broad. Pedicels 14-25 mm long.

Not common. Distinguished by the tubers, the emarginate-retuse petals, the rose coloured hairy filaments and awned sepals. Closely allied to the European Geranium tuberosum from which it differs in the glandular parts (in this respect similar to Geranium macrostylum), the smaller leaves, longer petioles (up to 25 cm) and a well developed petal claw.
