Herbarium data on bryophytes from the eastern part of Lithuania (1934–1940) in the context of science history and landscape changes

Abstract The paper deals with bryophytes collected by Polish researchers from the mires in the eastern part of Lithuania in 1934–1940 and deposited at the Herbarium of W. Szafer Institute of Botany, Polish Academy of Sciences (KRAM). The collection provides data on bryophyte diversity and distribution patterns in the mires of Lithuania. The collection (868 specimens) was revised in 2016–2017. Almost 90% of all herbarium specimens were collected by Irena Dąbkowska. The specimens were identified by the collectors themselves or by Polish bryologist Zygmunt Czubiński; 254 specimens of the collection were not identified. After revision, a total of 112 bryophyte species were ascertained in the collection, two of these (Palustriella decipiens and Polytrichum swartzii) have not been reported to Lithuania before. The specimens were collected in 47 localities, the mires in nearly half of them at the moment are disturbed due to drainage or use for peat extraction. Information about the localities of rare species Hamatocaulis vernicosus, Meesia triquetra and Mesoptychia rutheana is valuable for the estimation of their population status.
