Bucklandiella sudetica (Funck) Bedn. -Ochyra & Ochyra SPECIMENS EXAMINED. — Antarctica . West Antarctic Peninsula, Graham Coast, Wilhelm Archipelago, in the north-eastern part of Hovgaard Island, 65°07’14”S, 64°04’05”W, alt. 30 m a.s.l., on exposed rock surface above the moss bank and below the stand of Kiaeria pumila associated with Hymenoloma crispulum and Andreaea regularis , 25.II.2019, Parnikoza & Ivanets 300/19 (KRAM [B-257918]); same place and conditions, 12.II.2022, Parnikoza 03/22 (KRAM [B-262849]). REMARKS Grimmiaceae subfam. Racomitrioideae is represented by two genera in Antarctica which are segregates of the broadly conceived genus Racomitrium Brid. (Ochyra et al . 2003b; Bednarek-Ochyra et al . 2014; Sawicki et al . 2015). Of these, Racomitrium s.str. contains a single species, R. lanuginosum (Hedw.) Brid., which is exceedingly rare and so far recorded only from heated ground on the volcanic Deception Island (Lewis Smith 2005a, b; Ochyra et al . 2008b). In contrast, Bucklandiella Roiv. consists of no fewer than five species which are not prominent constituents of the moss flora in this biome, both in terms of frequency and cover (Ochyra et al . 2008a; Ellis et al . 2013a, 2017). Of all the species of this genus, B. sudetica is the most widely distributed, but generally infrequent and only quite abundant in places. One such area is the Graham Coast, where it is known from several sites on Galindez Island in the Argentine Islands, on Cape Tuxen, in the Berthelot Islands, Lahille Island and on the Barison Peninsula and its offshore island where it reaches its southernmost occurrence on the west side of the Antarctic Peninsula (Ochyra et al . 2008a). The discovery of the species on Hovgaard Island is thus a remarkable extension of its geographical range in this region to the northern part of the Wilhelm Archipelago (Fig. 5). Additionally, B. sudetica is scattered in the Danco Coast including the Palmer Archipelago and frequent in the South Orkney Islands and in the South Shetland Islands, and ...
