Rosulabryum andicola (Hook.) Ochyra Remarks. A widespread African-Neotropical species found from Chile north to the Southwestern US. This species replaces R. billarderii in warmer climates in Chile and is rare south of the Maule Region. It is found principally on damp to dry soil or soil over rock, rarely on fallen logs and tree stumps. The species is characterized by dioicous sexual condition, strongly rosulate stems, large leaves that are spirally twisted around the stem when dry, a costa excurrent in a short awn, a very well-developed wide limbidium, sharply serrate distal leaf margins, and brown filiform gemmae in the leaf axils of sterile shoots. The rhizoidal tubers are red to red-brown and can be> 1 mm in diameter. (Illustrations: Mohamed 1979 : 422, as Bryum andicola ; Magill 1987 : 382, as B. andicola ).
