colour as the capsule, adhering to the mouth of the capsule 

 with such singular tenacity, that out of many mature ones, 

 I have never seen it wanting, and it is separated with diffi-

I have every reason to conjecture that this very handsome 

 Hypnum must be of frequent occurrence in Canada, and very 

 probably throughout the northern division of the United 

 States ; it was collected by my friend, John Haldane, Esq., 

 in two localities, and, judging from the luxuriance of the 

 large masses he kindly preserved for me, it must exist in 

 great abundance. In both instances it appears to have grown 

 upon the trunks of (probably fallen) trees ; and in the centre 

 of the masses to have in part lost the creeping character, 

 from the stems and branches having been much crowded and 

 drawn up. 



I am not aware of any species with which H. Haldanianum 

 can be confounded.
