On rocks upon Craigalleach (Perthshire) and other of the 

 Breadalbane mountains, always in elevated and exposed si- 

 tuations, where its " gem-crowned stalks " seem " too tender 

 to bear one flake of snow." Pr. August. Bruch and Schim- 

 per justly remark that " this rare and elegant Moss presents 

 some analogy in the form of its capsule with B. Zierii." 

 Its tufts however are more compact, and the branches, from 

 the leaves spreading more, have a difl"erent appearance. 

 The lower leaves and tips of the upper ones are coloured of 

 a fine reddish-brown. It is found in several other alpine 

 districts of Europe, but nowhere common.
