 much appreciated. 



Jaccard, (1896-1900, F. H., 19, 20, 88, 193), has made many 

 detailed observations on the flora of Alpine meadows, and en- 

 deavoured, by statistical methods,* to bring into something 

 like order the peculiarities of their composition. 



Plant-Geography Monograppis, and Studies of Special 

 Formations. — No systematic attempt has been made in 

 Switzerland to treat uniformly the plant-geography of the 

 country, though many selected areas have been studied 

 in very great detail. As already mentioned, Heer's work on a 

 part of Kanton Glarus set the fashion in this kind of study. 

 The chief works in this direction, to mention only a few are those 

 of Briquet (1891-6, F. H., 65, 144, 145), one by Schroter on 

 ' St. Antonierthal im Prattigau ' (1895, F. H., 135), is an exceed- 

 ingly interesting study of a small district, and deals not only 

 with geographical and geological features, plant formations 

 and limits, but also many details concerning local agriculture. 

 The coloured map accompanying the paper not only indicates 

 the distribution of the dominant trees, rhododendron, Alnus 

 viridis, etc., but gives 32 types of meadow vegetation, the latter 

 sometimes regarded as an illustration of ' hair-splitting ' in 

 plant-geography. 



Chodat,* deals with the sand dunes near Lake Geneva, 

 and comp'ares the flora with that of dry, sunny, rocky slopes 

 (Felsenheide) . It is in this paper that he introduces the term 

 ' Garide,' a word compounded of Garigue and Arid. 



Aubert (1900, F. H., iii), discusses at great length the 

 immigration of the flora, in addition to descriptions of forma- 

 tions, limits, edaphic conditions, and the like of the Vallee 

 de Joux. 



Hegi,"!* discusses the question of glacial relics, concluding 

 that these species are confined to localities which were free from 

 ice during the last glacial period. He is supported in this by 

 Schmidt in his studies in Appenzell,* but this conclusion is
