 Autumn (late) . This distinct Moss was discovered in 1 S15, 

 by Mielichofer, at Schwarzwand, among tlie Alps of Salz- 

 burg, and has been subsequently found on most of the 

 mountain-ranges of Europe. We doubt not that it will yet 

 be found in other localities amid our snow-capped moun- 

 tains.
