Notes on a few mosses from South-Western 



Switzerland* 



by W. E. Nicholson. 



The following notes are the result of a short holiday in 

 Switzerland from the &^' to the 31^^ July 1901. From'^the 

 6'*' to the 15'^ July w^as spent at the Riffel Alp Zermatt, 

 where favoured by excellent weather, I was able to explore 

 the district as w^cll as my short visit would admit of. From 

 the ir)«*» to the 22"*^ July was spent at Glion-sur-Territet 

 above the Lake of Geneva, while after a stay of two days 

 at Aigle, whence an excursion was made to Les Plans-sur- 

 Bex, from tlie 24^^ to the 3J'^ July was spent at Diahlerets 

 in liic upper part of the valley des Ormonts. The districts 

 visited thus embraced portions of tJic principal zones of 

 vegetation, which have been recognized in Switzerland. Tlie 

 neighbourhood of the Lake of Geneva and llio lower por- 

 tion of the Rhone valley have several immigrants from the 

 Mediterranean region, such as Torlula membrani folia ^ Hook., 

 Grimmia crinUa^ Brid. and G. tergeslina^ Tomm. The woods 

 about Glion, Les Plans and Diablerets are very characteristic 

 of the subalpine zone, while the Riffel Alp, Zermatt, situate 

 as it is at the upper limit of the tree-hue, is an excellent 

 centre for exploring the riches of the alpine zone. 



I am much indebted to MM. J. Cardot and F. Renauld, 

 Culmann and M. 11. N. Dixon for assistance in determining 

 some of the more difllcult specimens. 



Upwards of 200 species were noticed, of which the 

 following are perhaps the most interesting : 



Buxbauniia Indusiala, Brid. Rotten pine trunks Les Phins 

 and Diablerets, c. fr. ; in scattered stems, rare and difficult 

 to find. As pointed out by Schimper it was generally asso- 

 ciated with Plaqiothecium silesiacum. 



Stvarlzia inclinata^ Ehrh. Terminal moraine of the Finde-
