Nomenclatural Novelties in the Bryaceae (Bryophyta)

Abstract

Abstract The taxonomic and nomenclatural history of the broadly conceived genus Bryum Hedw. is briefly outlined. Twenty-one species, originating mostly from the Southern Hemisphere and traditionally classified in this genus, have been transferred to the widely accepted segregates of Bryum, including six in Imbribryum N. Pedersen, three in Leptostomopsis (Broth.) J. R. Spence & H. P. Ramsay, one in Plagiobryoides J. R. Spence, nine in Ptychostomum Hornsch. and two in Rosulabryum J. R. Spence.
