Studies on mosses in the Falkland Islands: I. Bucklandiella and Codriophorus (Grimmiaceae)

Bucklandiella didyma (Mont.) Bednarek-Ochyra et Ochyra and Codriophorus laevigatus (Mitt.) Bednarek-Ochyra et Ochyra are recorded for the first time from the Falkland Islands. Bucklandiella heterostichoides (Cardot) Bednarek-Ochyra et Ochyra, B. membranacea (Mitt.) Bednarek-Ochyra et Ochyra and B. ptychophylla (Mitt.) Bednarek-Ochyra et Ochyra are newly reported from East Falkland and B. sudetica (Funck) Bednarek-Ochyra et Ochyra is a new addition to the bryoflora of West Falkland. In total, seven species of Bucklandiella Roiv. are currently known from the Falkland Islands and they are briefly characterised, their geographical range is surveyed and global distribution of selected species is mapped. The status of five species of Bucklandiella which are excluded from the bryoflora of the archipelago is briefly considered. A key to determination of species of taxa of the Racomitrioideae in the Falkland Islands is presented.
