Abstract: 

In the flora of the Chuvash Republic, 40 species of the genus are revealed. 11 of these (A. altaica, А. argutiserrata, A. barbulata, A. cheirochlora, A. exilis, A. gibberulosa, A. hebescens, A. oxyodonta, A. plicata, A. sibirica, A. vorotnikovii) are registered in the Republic for the first time. Earlier, two species (A. pustynensis Czkalov and A. obtusa auct. non Buser) were noted here erroneously. Species are revealed whose richness corresponds to the level seen in neighbouring regions and approaches the maximum possible. Species richness of the botanicalgeographical areas differs crucially between forest (20–27) and other (steppe/steppefied/outwash) landscapes (2–11) species.
