regret that circumstances should, till now, have prevented its 

 having been published in the way I had wished. It was 

 gathered by Mr. Menzies at Nootka Sound, in l/S^; and

 coast, by Dr. Scouler. 



This moss is quite unlike any species with which I am 

 acquainted, having almost as much the habit of a Hupnum^ 

 especially of the dendroid kind, as of a Bryum ; but the fruc- 

 tification is truly terminal, all the shoots springing from 

 beneath the perichaetium. The situation of the male flowers, 

 too, if such they may be called, is equally terminal. In the 

 shape and texture and spinous nerve of the leaf, this plant 

 agrees with my Hypnum spininervium {Muse. Eocot. t. 29.).
