Synopsis of the genus Oxytropis (Fabaceae) of Eastern Europe and the Urals

Abstract

Synopsis of the genus Oxytropis DC. in Eastern Europe (within the former USSR, including northwestern Kazakhstan) and the Urals is published, comprising 25 species, 1 subspecies, and 5 varieties. To compare, in the «Flora of the USSR» (Vassilczenko, Fedtschenko, 1948), only 17 species of the genus were listed for the same territory. The lectotypes of O. approximata Less., O. gebleriana Schrenk ex Fisch. et C. A. Mey., O. glabra DC., O. gmelinii Boriss., O. hippolyti Boriss., O. sordida (Willd.) Pers., and O. uralensis (L.) DC. are designated. Oxytropis baschkirensis Knjaz. is included in O. uralensis, whereas synonymization of O. songarica (Pall.) DC. and O. ivdelensis Knjaz. with O. uralensis is rejected. The new nomenclatural combination O. uralensis var. baschkirensis (Knjaz.) Knjaz. is published. Oxytropis baschkirensis subsp. skvortsovii Knjaz. is synonymized with the type variety of O. uralensis. A key for indetification of Oxytropis in Eastern Europe and the Urals is compiled.
