224 MOSSES AND HEPATIC^ OF SARK. 



Porotrichum alopccurum, and Hypnum denticulatum ; and five 

 hepatica?, viz., Lejeunia serpyllifolia, Di plop Ivy Hum albicans, 

 Plagiochila asplenioides, Saccogyna viticirfosa, and Nardia 

 scalar is, which have not been detected in Alderney, and I am 

 almost certain that most of these species do not grow there 

 at all. 



From the point of view of a bryologist, therefore, Sark 

 appears to be a much richer area than Alderney, and, judging 

 from Mr. Derrick's gatherings, I have no doubt whatever that 

 if both islands were equally well searched, the moss-flora of 

 Sark would equal, if it did not surpass, that of Alderney in the 

 number of species. A little careful research by an experienced 

 bryologist in the early spring and again in the autumn, when 

 many minute and obscure species are in a good state of deve- 

 lopment, would certainly add many species to the present list. 



The moss-flora of Sark, as now recorded, consists of 60 

 mosses and 22 hepatica?.
