NOTES

New to the southern hemisphere. The collection closely matches northern hemisphere material ( Spence 2014). This species along with Bryum dichotomum Hedw. tend to be more widespread than other species in the complex, most of which prefer Mediterranean-type climates. The bulbils are smaller than those in B. dichotomum , and generally there are 2-5 per leaf axil. The species has also recently been found in Magallanes Province of Chile in Tierra del Fuego (pers. comm.). Possibly introduced. A strict bipolar/South American species restricted to southern South America.
