This beautiful species, named for the gentleman who communicated 

 the specimens, differs from its nearest allies in the following particulars: 



From B. pendulum Schimp. in the longer collum and shorter pointed 

 lid. the free nodose endostome, the short seta, the smaller spores, and the 

 almost immarginate short-pointed imbricate leaves. 



From B. inelinatum Br. & Sch. in the free nodose endostome, the per- 

 sistent lid, the short seta, the almost immarginate leaves with less revo- 

 lute edges and uncolored costa. 



From B. lacustre Brid. in the long much-branched stems, appressed 

 leaves, shorter seta, slender nearly naked vaginule and polygamous 

 flowers. 



Type specimens have been deposited in the herbaria of the Na- 

 tional Museum, Harvard University and Columbia College.

 mention of which may be of interest. Though it is a ride of but three 

 hours in the cars from Boston, yet the characteristic Sowers are very, 

 different, as you are beginning to reach the northern limit of m ty plants
