2350. Nelson, James C. A comparison of the flora of southern British Columbia with 

 that of the State of Washington, as illustrated by the floras of Henry and Piper. [Rev. of: 

 Henry, Joseph Kate. Flora of Southern British Columbia and Vancouver Island. S6S p. 

 W. J. Gage & Co.: Toronto, 1915.] Torreya 19: 174-184. 1919.— Henry's Flora, although 

 covering a territory at least twice as large as the State of Washington, and extending to the 

 eastv/ard so as to include the Rocky Mountain flora, mentions only 2359 named forms as com- 

 pared with 2511 in Piper's Flora of Washington. Of these 1517, or about 60 per cent, are com- 

 mon to both manuals. Assuming equal thoroughness on the part of both authors, two con- 

 clusions seem to be justified. (1) That Washington is a region of more marked endemism than 

 British Columbia. (2) That the 49th parallel seems to come very near to a line marking the 

 extreme northward dominance of the Californian flora on the one hand, and the extreme 

 southern extension of the Alaskan flora on the other. In Henry's Flora there are 764 forms 

 not mentioned by Piper ; in Piper's 928 not mentioned by Henry. These species are arranged 

 by groups to show distribution and degree of endemism. A table of discrepancies in the case 

 of 18 of the larger genera is presented. Prof. Henry displays a commendable conservatism 

 in his conception of taxonomic relations. The book is marred by many inaccuracies in capi- 

 talization, grammatical agreement, orthography, abbreviation, citation and etymology, but 

 on the whole is a valuable effort to contribute to the fuller knowledge of the Northwest Flora.
