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. In nothing, however, is it so re- 
markable as in the large cylindrical deeply sulcate capsule, ‘and 
the long perichztial leaves compared with the shortness of the 
fruitstalk,
