Geranium aristatum, Freyn & Sint.

17. G. aristatum Freyn & Sint. View in CoL View at ENA , Bull. Herb. Boiss. 5: 587 (1897).

Like 15 but with deflexed hairs on lower part of stem; pedicels glandular-hirsute, deflexed during the maturation o f the fruit; sepals with arista 4-6 mm, and with very long (2-3 mm) eglandular hairs; petals 13 x 17 mm, oblong-elliptical, apiculate, somewhat deflexed, pale lilac with darker veins; mericarps sericeous towards the base, subglabrous above, with ridges as in 15. • Mountains o f S. Albania, S. Jugoslavia (Makedonija) and N. W. Greece. Al G r Ju. (18-21) G. tuberosum group. Perennials with short, thick, often tuber-like rhizome. Stem single, 2Q-60 cm, erect, pubescent, with 0-2 pairs of cauline leaves in addition to the pair of large, leaf-like bracts at the base of the inflorescence, which consists of 2 main branches and sometimes a smaller terminal branch between them, each branch terminating in a corymbose cyme. Basal leaves divided for at least 95 % o f the radius into 5-9 lobes, which are variously toothed, lobed or pinnatisect. Cauline leaves (if present) and bracts also deeply lobed, but the lobes narrower and less deeply segmented. Petals broadly obovate, deeply emarginate, purplish-pink. Mericarps hairy, without ridges. The four species included in this group appear to differ constantly in well-correlated characters, despite a considerable similarity in general appearance.
