Banks and on heaths, particularly in sub-mountainous countries. Fr. 

 (rare) Nov. — This fine species, with the following (except B. Tozert), 

 form a natural groupe, (Mnium of Schwaegr. not of Sm. nor Brid.) dis- 

 tinguished by their large lax lurid or deep green foliage, and their barren 

 stems which are often creeping. The inner peristome is of a firm and 

 rigid texture. The present and the following species have perhaps the 

 largest leaves of any British moss; and these are collected on the top 

 of the stem where they spread out horizontally. 



** Daves with their margins evidently thickened.

Moist banks and in woods, common. Fr. Apr. — This is one of the 

 largest and handsomest of all mosses. Many bright-coloured tela fre- 

 quently arise from the same point. When the seta- are numerous, some 

 of the outer ones are axillary. WiU.
