Taxonomic notes on Calymperes erosum Müll.Hal. (Calymperaceae), C. palisotii Schwägr. and related West African taxa

Abstract

The lectotype for Calymperes erosum Müll.Hal. is re-established, and lectotypes are designated for three West African taxa: Calymperes asterigerum Müll.Hal. ex Besch., C. leucomitrium Müll.Hal. and C. proligerum Dusén. Calymperes asterigerum and C. leucomitrium are placed in synonymy with C. erosum, and C. proligerum with C. palisotii Schwägr. A revised key to the seven species of Calymperes occurring in West Africa is provided.
