PLANT GEOGRAPHY AND ECOLOGY 

 IN SWITZERLAND.* 



(PLATH X\-,) 

 T. W. WOODHEAD, Ph.D., I'.L.S. 



During my stay in Ziirich (1905-1906), an opportunity was 

 afforded me of seeing much of the work done in the direction of 

 plant-geography and ecology, under the guidance of Dr. C. 

 Schroter, professor of botany in the Federal Polytechnic 



As these subjects are exciting a considerable amount of 

 interest in Great Britain at the present time, and especially in 

 the North of England, it might be useful to indicate, as well as 

 limited space will permit, the extent and nature of the work 

 accomplished by Swiss botanists, and so draw attention to 

 papers which might otherwise be overlooked by workers here. 



The interest of Swiss botanists in plant-geography is of long 

 standing, and the number of workers very great, so much so 

 as to render it impracticable to give a complete bibliography. 

 I have, however, attempted to particularise the more important 

 items, and for the benefit of those who may wish to examine a 

 larger series of the original papers, I have given where possible 

 references to a Swiss bibliography , f which is indispensable to 

 an^^one desiring a complete list. In the following notes, there- 

 fore, the year of publication, and the page number of ' Flora 

 Helvetica ' will be given in brackets, e.g. Josias Simler, (1633, 

 F. H. 4) means that Simler 's work was published in 1633, 

 complete reference to which will be found in ' Flora Helvetica ' 

 under that date on page 4. By this means many more papers 

 can be indicated than would otherwise have been practicable. 



In the preparation of this paper, I have received the greatest 

 assistance from Prof. Schroter, who went to considerable trouble 

 in gaining for me access to the original papers, a number of 

 which, especially the more recent ones, he generously presented 

 to me. 



Early Period. — Swiss botanists were early in the field in 

 recognising the fundamental principles of geographical botany, 

 and in such a country as Switzerland, one is not surprised to
