Range extensions for moss species on the west side of the Antarctic Peninsula

New distributional data are presented for 12 species of moss collected from the Graham Coast and Danco Coast together with their offshore islands on the west side of the Antarctic Peninsula. Pohlia wahlenbergii (F.Weber & D.Mohr) A.L.Andrews is new to the Antarctic Peninsula and the Graham Coast and it is the southernmost station of the species, whereas Warnstorfia sarmentosa (Wahlenb.) Hedenäs is new to the Danco Coast. Schizymenium pusillum (Hook. & Wilson) A.J.Shaw is recorded for the first time on the Antarctic Peninsula mainland, and Schistidium rivulare (Brid.) Podp. is found at its southernmost locality on Cape Pérez on the mainland Graham Coast. Andreaea regularis Müll.Hal., Kiaeria pumila (Mitt.) Ochyra, Bucklandiella sudetica (Funck) Bedn.-Ochyra & Ochyra, Warnstorfia fontinaliopsis (Müll.Hal.) Ochyra and Pohlia nutans (Hedw.) Lindb. are new for Hovgaard Island in the Wilhelm Archipelago, and the latter is additionally recorded for the first time from Point Rasmussen on the mainland Graham Coast. Bryum pallescens Schleich. ex Schwägr. is new to Darboux Island, while Polytrichum juniperinum Hedw. and Brachythecium austroglareosum (Müll.Hal.) Kindb. are new to Lahille Island in the Grandidier Channel. Updated distribution maps for all species in the study areas of the Danco and Graham Coasts and the northern Antarctic Peninsula are presented. The moss floras of the Graham and Danco Coast regions consist currently of 51 and 47 species, respectively.
