Contributions to an updated checklist of the German flora (Pteridophyta, Spermatophyta)

Abstract

Details concerning the nomenclature of the taxa Achillea collina, Anthriscus, Betula pubescens subsp. carpatica, Camelina microcarpa, Hordelymus, Populus nigra subsp. betulifolia, Silene baccifera, and some subspecific names published by Cesati respectively are discussed. In the genus Urtica an alternative taxonomical treatment is proposed. Consequently, the following two combinations are implemented: Populus nigra subsp. betulifolia and Urtica subinermis.
