K. Regelio indėlis Diphasiastrum Holub genties taksonominei įvairovei Lietuvoje pažinti

Abstract

Flora of Lithuania had a hitherto two known species of the genus Diphasiastrum (D. complanatum and D. tristachyum). However, in all the neighbouring Lithuania countries, another one species of the genus D. × zeilleri is found. Therefore, the identification key of the three aforesaid genus Diphasiastrum species was formed and the taxonomy revision of the specimens of the collection of the Herbarium of Vilnius University was carried out in order to determine whether the specimens of the D. × zeilleri species were not amongst them. After completing the taxonomy revision, it has been revealed that in approximately a one third of D. × zeilleri species were found amongst the specimens of two type collections. The first specimens of this species came up into the collection of the Herbarium of Lithuanian established by C. Regel in 1925 yet.
