Mosses from the Western Highlands. 

 By James Stirton, M.D., F.L.S. 



Leucobryum PUMir.UM {W\c\\y^.) has been found at last near 

 Gairloch, Ross-shire, on the 20th of September 1911. Bryo- 

 logists have searched during a long course of years for this 

 moss throughout Europe and Great Britain, but until lately 

 quite in vain. I have a distinct recollection of hearing Pro- 

 fessor Schimper of Strasbourg, author of the " Bry. Eur.," 

 while on a visit to this country in 1865, urge those interested 

 in mosses to institute an organised search for a Leucobryum 

 having leaves with deeply cucullate apices. Several in 

 Glasgow directed their attention for twenty years thereafter 

 towards the discovery of such a moss, but without success. 

 In 1882 a Mr. Piffard discovered, in the New Forest, England, 

 L. uihms (Hampe), then reckoned a variety of the common 

 L. glaucum (L.), but now named L. albidiiDi (Lindeb. ), for 

 what reason I know not. 



At this stage the search gradually abated for nearly thirty
