Results of further investigation of biogeographical and chorological peculiarities agamospecies (as an example Alchemilla L. [Rosaceae]) for Euroasian floras demonstrate new confirmation of its floregenetic equivalent for different biparental species. Arealogical disjunctions corresponding to general florogenetic peculiarities of regional floras are characteristic of some species of the genus. For example: A. walasii Pawl. - mountain-planar disjunction species (Carpathians Mt. - Volyno-Podolian elevation - Belorussian Polissja), A. incisa Bus., A. firma Bus. - alpine-mountain Alps-Carpathians disjunction species, A. propinqua Lindb. F. - mountain-planar disjunction species: Carpathians Mt. (Fatra, Tatry, Western Carpathians) - Sudety - Middle Russina regions, A. gorcensis Pawl. - mountains Carpathians-Balkan disjunction species: Gorcy - Chywchyny - the Balkan Mt., etc. These disjunctions of areas of these species demonstrate its development (as separate taxa) in general regional florogenetic process. It is necessary investigations of agamospecies from different taxonomical groups for confirmation of this thesis.
