The species which is the single real local
endemic species for the Transylvanian Basin
Astragalus peterfii Jav. was discovered only
in 1916 in the vicinities of Suatu village in the western central
part of the Transylvanian Basin. It is a xeric-mesoxeric steppe
species closely related to Astragalus vesicarius L. In no
way this octoploid taxon can be paralleled with Astragalus
vesicarius ssp. pastellianus as one study unconvingly tried to
affirm in a low estate journal from Italy. More probably
Astragalus peterfii is a result of autoploid speciation
which affected a local isolated group of populations of
Astragalus vesicarius. Still such two populations still
exist north-east of Cluj-Napoca, totally isolated from the compact
populations of Astragalus vesicarius from the western and
south-western Transylvania.
The population from Suatu - Banffy Hill
The population from Caianu - Fegheu Hill
