A. gevashensis Chamb. & Matthews in Notes R.B.G. Edinb. 29: 296 (1969). Dwarf, cushion-forming shrub. Leaf rachis spiny, straight, white-hairy. Leaflets 5-10(-16) mm, narrowly elliptic, mucronulate, densely white simple-pubescent, 5-8-paired. Stipules 9-11 mm, triangular-lanceolate, glabrescent, white-ciliate. Inflorescence globose to ovoid, occasionally elongate and lax, 15-30-fiowered; flowers 3-4 per leaf axil. Bracts 7-10 mm, linear, canescent. Bracteoles absent. Calyx 13-16 mm, white-pilose, tube 7-8 mm; teeth setaceous. Corolla violet-pink; standard 17-19 mm, platonychioid. Fl. 6-8. Rocky slopes, 1980-2590 m. Type: [Turkey] B9 Van: d. Gevaş, Artos Da., 2590 m, D. 22741! S.E. Anatolia. B9 Bitlis: d. Tatvan, Karz Da., above Kotum, 1980 m, D. 22268! 15 km E of Tatvan, 1850 m, Rix 352! 353! Endemic; Ir.-Tur. element. Related to A. karabaghensis, but distinguished by its densely hairy leaflets, etc. One of the specimens from nr. Tatvan (Rix 352) differs from the remainder in having a lax, elongate inflorescence and leaflets up to 16 mm long. This is considered to be no more than a shade form, especially since the other specimen from the same locality (Rix 353) resembles the remaining specimens in these respects.
