Alchemilla xanthochlora
Alchemilla filicaulis
Alchemilla xanthochlora was recognized by P. A. Rydberg (1908–1918) and M. L. Fernald (1950) as A. pratensis attributed to F. W. Schmidt, as typical A. vulgaris Linnaeus by M. L. Fernald and K. M. Wiegand (1912), and as A. vulgaris var. vulgaris by B. Boivin (1966b). Actually, Schmidt published a varietal name [A. vulgaris var. pratensis F. W. Schmidt, A. pratensis (F. W. Schmidt) Opiz], which does not apply to this species nor does A. vulgaris.
