6. Rosulabryum densifolium (Brid.) Ochyra

Remarks.

A robust species distributed throughout the Neotropics, primarily along the mountain chains from Mexico south to Chile, and throughout the Andes ( Ochi 1980). It is common at higher elevations, often above 3000 m, but can also occur in the lowlands, and is found along streams and in wetland areas on wet soil or rock. The species is characterized by its dioicous sexual condition, long evenly foliate stems with large narrowly ovate leaves, a costa excurrent into a medium to long awn, strong limbidium, sharply serrate to denticulate distal leaf margins, with the teeth often double, and brown to red-brown rhizoidal tubers ( Ochi 1967: 30, as Bryum densifolium ).
