(Hypnum alleghaniense, Canad. Musci, No. 102). 



It is more allied to T. Leibergii, Britton, than to T. alle- 

 ghaniense, Bryol. eur. ; but is perhaps only a subspecies. It 

 differs indeed: nearly all leaves ovate-oblong with a subulate 

 acumen. Stem sometimes with paraphyllia; branches after 

 complamte. Dioecious.
