Povilas Snarskis’ Collection of the Poaceae Specimens, Newly Discovered in the Herbarium of Vilnius University

Abstract We newly found a collection of the Poaceae specimens deposited at the Herbarium of Vilnius University (WI), collected by Povilas Snarskis mainly from eastern Lithuania in 1943–1960. The collection consisted of 67 herbarium sheets representing 28 species, including endangered species Glyceria lithuanica. The collection provided new data on abnormal growth forms of common Lithuanian grasses and the distribution of rare and endangered Poaceae species in eastern and southern Lithuania. The discovered Glyceria lithuanica specimen is the oldest of all known records of the species in Lithuania.
