lation to Bryum, as Leskea does to Hypnum. This mode 

 of structure too, both in Pohlia and Leskea is generally, but 

 unfortunately not always, accompanied by an erect capsule. 

 We are, however, now acquainted with many species which 

 have interposed ciliae, so minute and imperfect that it would 

 be difficult to say to which division the species possessing 

 them should belong:. 



In regard to the individual here figured, it is totally unlike 

 any species of Bryum hitherto described ; and I have much 

 pleasure in dedicating it to my friend Dr. Gillies, its disco- 

 verer, whose botanical collections, made in a previously un- 

 explored part of South America, are destined to afford some 

 of the most interesting materials of the present publication.
