214 INTRODUCTION TO PLANT GEOGRAPHY 



For useful examples in several instances, reference may be made to 

 R. Good's The Geography of the Flozvering Plants, second edition (Long- 

 mans, London etc., pp. xiv + 452, 1953), and for a comparison with 

 zoogeographical areas to M. L Newbigin's Plant ami Animal Geography 

 (Methuen, London, pp. xv + 298, 1936). 



A valuable example of detailed mapping of the ranges of individual 

 species in a well-known region (northwestern Europe) is E. Hulten's 

 Atlas over Vdxternas Utbredning i Norden (Stockholm, pp. 119 + 512, 

 1950). A somewhat similar project is afoot for the British Isles, and it 

 is to be hoped that, in time, more and more regions will be covered in 

 this manner. For the ranges as known to date of many different species 

 and larger groups, see Die Pflanzenareale (Fischer, Jena, vols. I-V, 

 1926-40). 



The floras of different areas are dealt with in numerous works to which 

 S. F. Blake & A. C. Atwood's Geographical Guide to Floras of the 

 World affords the most comprehensive introduction and selective biblio- 

 graphy. Part I, covering ' Africa, Australia, North America, South 

 America, and islands of the Atlantic, Pacific, and Indian Oceans ', was 

 published in 1942 by the United States Government Printing Office, 

 Washington, D.C. (U.S. Dept. Agric. Misc. Publ. No. 401, pp. 1-336), 

 while Part II, treating western Europe, is to be published by the same 

 agency. It is contemplated that a third part will cover the rest of the 

 world.
