J.R.Spence SPECIMEN EXAMINED. — Falkland Islands . East Falkland , road to North Arm , Bodie Creek culvert , 51°50’9.6”S , 59°7’8.4”W , cliff at shore , 5 m a.s.l., 12.I.2015 , 15/779 ( MNH ). NOTES A small species in the Rosulabryum capillare (Hedw.) J.R.Spence complex characterized by evenly foliate stems, a weak costa, and numerous filiform leaf axil gemmae, found in temperate climates of North America and the Caribbean ( Spence 2014 ). Possibly introduced, but old reports from South America exist (summarized in Greene 1986 ). See Spence (2014) for confusion on the correct name for this species. The type does not match the species known as R. andicola (Hook.) Ochyra (cf. Haji Mohamed 1979 ), and more work is needed to resolve the issue. A disjunct bipolar/South American temperate species.
