Abstract

Astragalus tenuifolius L. is shown to be a separate species, different from A. austriacus Jacq. The lectotype of A. scopaeformis Ledeb., a heterotypic synonym of A. tenuifolius, is designated. The species, formerly known under the illegitimate superfluous name A. tauricus Pall., is redescribed under the new name A. petri-simoni Knjaz. The race of A. tenuifolius s. l. distributed in the southern (deserted) steppe zone is described as a new species A. turgaicus Knjaz. An original key for identification of the species of A. austriacus s. l. and A. tenuifolius s. l. complexes is compiled. A list of studied herbarium specimens of A. tenuifolius s. l. species and a map of their distribution are given.
