Erodium absinthoides Willd. (sens strict.) Leaves are silvery grey, narrowly oblong, length 2-4 times the width, with segments laxly and deeply bipinnate into lanceolate acute lobes, densely canescent. The flowering stems bear 1 to 12 peduncles of white flowers with notched petals in June. Sepals with a long mucro 2 - 2.8 mm; beak is 4 to 4.5 cm. Found at 100-1600 m, western central Turkey.


Erodium armenum (Trautv.)Woronow Leaves are grey-green, narrowly oblong, length 2-4 times the width, with segments laxly and deeply bipinnate into lanceolate acute lobes, adpressed pilose. The flowering stems bear 1 to 12 peduncles of lavender-blue flowers in July and August. Sepals with a short mucro; beak is 3.5 to 4 cm. Found at 2300-3200 m, eastern Turkey, Armenia and Georgia.


Erodium elatum (Form.) R.T.F. Clifton Leaves are grey-green, oblong, 2-3 pinnatisect, with ultimate segments narrow linear. The flowering stems bear peduncles of 4 to 8 pink to bluish-violet flowers in April and May. Sepals with a long mucro of 1.5 to 2 mm. The beak is long being 4.5 to 6 cm. Found above 1600 m, in Europe, in Bulgaria, Greece, Bosnia, Serbia and Macedonia.


Erodium haradjianii P.H.Davis Leaves are greyish, oblong-ovate, length 1.5 times their width, pinnatisect with segments lobed only to the middle, with short obtuse teeth. The flowering stems bear 1 to 2 peduncles of 3 to 6 white flowers in July and August. Sepals with a short mucro. The beak is short at 2.5 to 4.2 cm. Found 1500 to 2000 m, endemic to Turkey in one province Osmaniye in the north Amanos Mountains at Düldül Dag.


Erodium latifolium (Davis) R.T.F. Clifton Leaves are silvery, ovate, length 1.5 times their width, simply 1-2-pinnatifid, with short obtuse teeth, leaf surface is subsericeous. The flowering stems bear 1 to 2 peduncles of bright pink flowers in June and July. Found 2500 m, only found in one location on rough scree limestone in Turkey; province Trabzon.
