This very handsome moss comes in general habit nearer to our 
Hypnum dendroides than to any other that I know; yet it is 
very different even from that. Jn nothing, however, is it so re- 
markable as in the large cylindrical deeply sulcate capsule, and 
the long perichetial leaves compared with the shortness of the 
fruitstalk. : |
