Abstract (English)

New localities of an Austria-wide G-classified species are named for Bolboschoenus laticarpus. A new locality of a species classified as CR in the Bohemian Massif in Austria is mentioned for Carex viridula (= C. oederi). New localities of species classified as CR in the Pannonian region in Austria are named for Asplenium septentrionale, Carex hostiana (status questionable) and Stachys alpina.
