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 ).
