5. Rosulabryum coloratum ( Muell. Hal.) J.R. Spence

Remarks.

A relatively uncommon species found principally in semi-arid regions in the central and northern regions of Chile and adjacent areas of Bolivia, found on sandy soil or soil over rock, often near streams. The species is characterized by its dioicous sexual condition, evenly foliate stems, large narrowly ovate leaves that are spirally twisted around the stem when dry, a weak limbidium distally, and brown to red-brown rhizoidal tubers. Ochi (1980) had synonymized it with R. canariense but it is treated here as a good species (see below under R. canariense ). (Illustration: Ochi 1980: 148, as Bryum canariense ).
