ATLANTIC SPECIES OF HEPATIC/E IN SCOTLAND 123 



Gymnomitrium crenulatum. Herberta adunca. 



Marsupella Stableri. Scapania gracilis. 



Jamesoniella Carringtoni. S. ornithopodioides. 

 Anastrophyllum Donianum. 



Anastrophyllum appears to have its headquarters in the 

 Eastern Grampians unless further search shows this to be 

 in Sutherland. Herberta seems to be confined in the 

 Eastern Grampians to the Forfarshire hills. The Marsupella 

 is a minute species with its distribution very imperfectly 

 known. The others are much more plentiful on the western 

 watershed. 



One recent addition to our flora, LopJiozia atlantica, has 

 been found only in a single locality in Caithness. It cannot 

 be classed at present in any of the above divisions.

 in England and Ireland as regards their distribution, we 

 find- 



1. Species which occur in Scotland but have not been 

 found in England :
