Potentilla blanda Sojak may be mistaken for dwarf forms of Potentilla hololeuca Boiss. on the herbarium sheets since both these species are pentafoliate and have floccose-tomentose stems and petioles. Potentilla blanda, however, is clearly differentiated from Potentilla hololeuca wh en closely examined. The former has digitate leaves Whi le the latter has pinnate leaves with lower remote pair and thus they are in two different sections.

A rare species, found up to 4,800 m.
