If Plagiochila exigua be considered distinct from P. 

 tridenticnlata it must be added here. 



All the European Atlantic species have been found in 

 the British Isles, and the following have not been found 

 elsewhere in Europe : 



Marsupella Stableri. Radula Holtii. 



Acrobolbus Wilsoni. Lejeunea flava. 



Plagiochila ambagiosa. L. Holtii. 



Cephalozia hibernica. L. Macvicari. 



Bazzania Pearsoni. Microlejeunea diversiloba. 



Scapania nimbosa. Frullania microphylla. 



Radula voluta. 



To these might be added Metzgeria /iainata,Jauiesoniella 

 Carringtoni, Mastigophora Woodsii, and Frullania gennana,

 The flora of these islands is generally admitted to be British

 only in Ireland. 



The species common to the west of Norway and west 

 of France are : 



Plagiochila punctata. Lepidozia pinnata. 



P. spinulosa. Scapania gracilis. 



Saccogyna viticulosa. Harpalejeunea ovata. 

 Adelanthus decipiens. 



Norway has the following, which have not been found 

 in France : 



Gymnomitrium crenulatum. Clasmatocolea cuneifolia.

Sphenolobus Pearsoni. Radula aquilegia. 



Plagiochila tridenticulata (as R. Carringtonii.
