Some Contributions to the Phytogeography of 

 Southern California. 



There have recently appeared three papers on plant distribu- 

 tion, to which the attention of the botanists oi Southern Cali- 

 fornia should be called. They are the following: 



Die pflanzengeographische Gliederung Nordamerikas. A. 

 Engler. Notizblatt des K. K. Gart. u. Mus. zu Berlin, Appendix 

 ix. 1-94. (May, 1902). 



Notes on Plant Distribution in Southern California, U. S. A. 

 R. E. B. McKenney. Beihefte zuni Bot. Centralblatt. x. 166-178 

 (1901). 



A Sketch of the Flora of Southern California. S. B. Parish. 

 Botanical Gazette xxxvi. 203-222, 259-279 (September and Oc- 

 tober, 1903). 



A paper of considerable importance to students of plant geog- 

 raphy is the one in which Professor JEngler outlines a scheme to 

 serve as a basis for the arrangement of American plants in the 

 royal gardens near Berlin. The American botanist will be most 

 interested in the manner in which he has divided our continent 

 into regions and minor divisions. Its first division is into four 

 regions (gebiete), the Arctic, Subarctic, Atlantic, and Pacific. 

 The Pacific region he subdivides into: (1) the province of Pa- 

 cific Coniferae, (2) the Rocky Mountain province, and (3) the

 province of Pacific Coniferae he finds a Northern zone and a 

 Southern zone, the latter comprising: (a) the district (bezirk) 

 of tlie coast forests of California and (b) the forest district of
