West Antarctic Peninsula, Graham Coast, Grandidier Channel, Lahille Island at the north-eastern entrance of Leroux Bay west of Barison Peninsula, 65°33’12.89”S, 64°23’42.14”W, on ground in the bryophyte carpet and mat subformation, 7.II.2020, Parnikoza 6B/20 (KRAM [B-259591]). REMARKS Polytrichum juniperinum was found on Lahille Island on a unique vegetated point on the island’s south-western coast in the bryophyte carpet and mat subformation, with patches of the grass Deschampsia antarctica É.Desv.
