9. Rosulabryum perlimbatum (Cardot) Ochyra

Remarks.

A common and widespread species of the subantarctic forests and moorlands of the Magallanes and Aisén Regions on damp to wet soil, fallen logs, and tree stumps (Ochi 1982). Reports from further north are likely misidentifications and are either R. andicola or R. billarderii . This is a robust species with dioicous sexual condition, rosulate stems, sometimes with 2+ interrupted clumps along stems, large leaves that are contorted to somewhat imbricate when dry, serrulate distal leaf margins, an extremely wide limbidium of 4+ rows distally, and brown to red-brown rhizoidal tubers. The wide limbidium often gives the leaves a white-margined appearance. The species is also found in Argentina, the Falkland Islands, and extreme southern New Zealand (Illustrations: Mohamed 1979: 422, as Bryum perlimbatum; Fife 2015: 87, as R. perlimbatum).
