Corolla uniformly yellowish; stan­ dard entire or rarely weakly emarginate at apex. • Valleys of E. Italian Alps; ^.Bulgaria.

A. tarchankuticus Boriss. , Not. Syst. (Leningrad) 14: 222 (1951), from Krym, and A. pseudoglaucus Klokov , Not. Syst. (Leningrad) 15: 50 (1953), from S. Ukraine, are perhaps to be included in this subspecies; the status of the plants from Bulgaria is also uncertain.
