Based on collections made by R. S. Tangney from the National Museum of Wales, eight taxa of the moss family Bryaceae Rchb. are newly recorded for the Falkland Islands, including Bryum funkii Schwägr., Bryum microimbricatum Ochi, Bryum platyphyllum Schwägr., Bryum barnesii J.B.Wood ex Schimp., Imbribryum clavatum (Schimp.) J.R.Spence & H.P.Ramsay, Ptychostomum gayanum (Mont. ex Müll.Hal.) Ochyra & Bedn.-Ochyra, Rhodobryum cf. roseodens (Müll.Hal. ex Geh.) Paris, and Rosulabryum flaccidum (Brid.) J.R.Spence. These additions increase the Bryaceae flora of the archipelago to 28 species. The northern hemisphere species, B. barnesii, is also new to the southern hemisphere. Phytogeographic analyses reveal that the Bryaceae of the Falkland Islands have strongest affinities with southern South America, followed by southern New Zealand, Tasmania and the subantarctic islands including the Prince Edward Islands, Macquarie Island and Îles Kerguelen. A key to the species is included.
