PLANT GEOGRAPHY AND ECOLOGY 

 IN SWITZERLAND. 



T. W. WOODHEAD, Ph.D., F.L.S. 



[Continued from page 1^4). 

 Of works dealing with special branches, mention may be 

 made of t he paper by Vogler.* This contains a detailed account 

 of the morphology and biology of the seeds of ten orders of 

 Alpine plants, the adaptations for dispersal of the seeds of the 

 plants of the whole Swiss flora, and a detailed comparison 

 between plants of the plains and Alpine plants as to their means 

 of dispersion. Oettli,| studied the southern rocky calcareous 

 slopes of the Churfirsten and the Santis, and deals in an ex- 

 haustive manner with the habitats and adaptations of. rock 

 plants. 



Schellenberg has done much work on the importance of 

 hemi-c ellulose as a food reserve in the leaves, etc. of Alpine and 

 other plants, while Keller (1887, F. H., 192) Briquet, (1896, 

 F. H., 192), Fisch (1899, F. N., 192), and Giinthart,J publish 

 many observations they have made on the biology of the flowers 

 of Alpine plants. 



Forests and Forestry Studies. — Forestry occupies an 

 important position in the economy of Switzerland. The 

 literature is very extensive, most of the wwks mentioned in 

 this paper contain chapters on the forests of the regions dealt 

 with. Of recent papers, special reference may be made to the 

 following : — E. Geiger's, § * Das Bergell ' and Bettelini's, || 'La 

 flora legnosa del Sottoceneri,' deal in an excellent manner with 

 the distribution of trees and shrubs of the districts concerned, 

 and Dr. Brunies \ has recently completed a study of the flora 

 of the ' Ofengebietes,' which besides chapters on geology, 

 climatology, formations and flora contains an elaborate study
