Cryptogamic Plants from the Ionian hlands. 343 



1 have to regret, in describing this species, that the fruc- 

 tification is too young to exhibit anything besides its general 

 form. This prevents me from ascertaining the nature of the 

 peristome, which probably resembles that of T. subulota, to 

 which moss our species is most nearly allied. In the leaves, 

 however, there is much greater length and narrowness, Avith 

 almost the entire absence of an apiculus. 



I have bestowed the specific name in honour of the illustrious 

 individual by whom the collection was brought home.

I have not access to Wahlenberg's plate and description in Act. 

 Holm. 1800, of F. ealearea, which, according to Swartz, is the same 

 as Hooker's F. hibernica. Thus, in order to avoid uncertainty, 1 

 have been obliged to keep up the more recent name.
