Taxonomic status and typification of the neglected name Calamagrostis vinealis (Poaceae, Agrostidinae)

The unresolved name Calamagrostis vinealis Steudel (Poaceae, Agrostidinae) is lectotypified and its taxonomic identity is discussed based on the discovery of Baumgarten’s collection at the P herbarium (P02142817), based on which this name was assigned. This collection appears to be a mixed gathering of Calamagrostis epigejos (left-hand specimen) and C. arundinacea (right-hand specimen). Here, the left-hand specimen is designated and labeled as lectotype of the name Calamagrostis vinealis, and in consequence, C. vinealis is a later heterotypic synonym of C. epigejos.
