“…R. lanuginosum is very widespread on South Georgia (Bell, 1974) but it seems to be represented mostly by the type subspecies, whereas subsp. geronticum is only occasional (Ochyra, Bednarek-Ochyra & Lewis Smith, 2002). Accordingly, the identity of R. glaciale with R. lanuginosum is here confirmed.…”

A new species, Racomitrium patagonicum Bednarek-Ochyra & Ochyra, is described from southern South America. A herbarium name, R. senile Schimp. in A. Jaeger, is considered synonymous with R. patagonicum and confusion associated with its interpretation is explained. The new species belongs to the type subgenus of Racomitrium and is closely alied to R. lanuginosum (Hedw.) Brid. from which it differs by the very long and broadly decurrent, ruffled or wavy margins of the hyaline hair-point, broadly canaliculate leaves and dull green, strongly papillose laminal cells. Grimmia glacialis Müll. Hal., hom. illeg. (=Racomitrium glaciale Kindb.) from South Georgia is typified and this name is considered synonymous with Racomitrium lanuginosum subsp. lanuginosum. Distribution of the new species is mapped. A key to species of Racomitrium subg. Racomitrium is provided.

“…In the Northern Hemisphere it has a continuous range throughout much of the Holarctic, reaching maximum possible latitudes in the Canadian Arctic Archipelago and Spitsbergen. In the Southern Hemisphere W. exannulata is common and locally abundant in Tierra del Fuego (Ochyra & Matteri, 2001) and western Patagonia, and occasional on the Falkland Islands and subantarctic South Georgia (Ochyra et al 2002). Eastwards it occurs in southeastern Australia, Tasmania and on the South Island of New Zealand.…”

“…In the Subantarctic, the species has so far been known from a highly isolated station on Îles Kerguelen (Ochi, 1972) Bryum orbiculatifolium is a very characteristic and readily recognised species with deeply concave, orbicular leaves. It has been very occasionally collected in western Patagonia (Ochi, 1982), subantarctic South Georgia (Ochyra, Bednarek-Ochyra & Lewis Smith, 2002) and Tristan da Cunha (Dixon, 1960 as Bryum cymbifoliellum). It extends to the northern maritime Antarctic where is known from the volcanic Leskov Island and Candlemas Island in the South Sandwich Islands archipelago (Convey et al, 2001) and Deception Island in the South Shetland Islands (Lewis Smith, 2005a, b, c) and recently, it was also encountered on the continent in the Schirmacher Oasis in Dronning Maud Land (Ochyra & Singh, in press).…”
