A. monachorum Sirj. , Feddes Reperì. 47: 242 (1939), from Athos, appears to be intermediate between 63 (a) and 64; it is like 64 but has glabrous stipules, calyx 20-23 mm and standard 20-24 mm. A. jankae Degen & Bornm. , Magyar Bot. Lapok 18: 17 (1919), from S. Bulgaria, appears to be intermediate between 64 and 65; itis like 64 but has the leaflets hairy above, and the bracts ovate. The relationship between these two taxa and 63 (a), 64 and 65 is obscure.
