CAMPYLIUM (MUSCI, AMBLYSTEGIACEAE), A NAME TYPIFIED BY PFEIFFER

The moss genus Campylium is heterogeneous. An early type designation b y Pfeiffer had been overlooked. Arguments for and against possible con servation of the name with the traditional type, C. hispidulum are ass essed. In the light of new taxonomic evidence, adoption of the type de signated by Pfeiffer, C. stellatum, is recommended. In this way, that well-known species name and the phytosociological designations based o n it will remain unaltered, whereas C. hispidulum must be transferred to the genus Campylophyllum, which is closely related to some species of Hypnum.
