NOTES

This species is related to others transferred to the genus Plagiobryoides J.R.Spence. Although reported as new to the Falkland Islands it may have been previously reported as the endemic Bryum uvidum . However, the poor quality of the material comprising the type could not be confidentially assigned to this species, as Ochi (1982) indicates that it may be either B. platypyllum or Imbribryum clavatum . Molecular and morphological studies are in progress on the status of Plagiobryoides and other related species including B. gilliesii from southern South America (Toren, Spence, Shevock, Larraín pers.comm.). A southern hemisphere/South American temperate species.
