Clements, F. E. and Edith S. Clements. Rock}»^ Mountain 

 Flowers. An illustrated guide for plant-lovers and 

 plant-users. White Piain s. N. Y. and New York City. 

 (The H. W. Wilson Company, 1914.) 



A large octavo of over 400 pages, with 22 piain plates and 25 

 color reproductions by Cockayne of well done aquarelles by Mrs. 

 Clements. 



The work is essentially a series of Keys for the differentiation 

 of families, general and species, the latter rather broadly conceived 

 as viewed by an experimental ecologist to whom their relationships 

 and divisibility are an organic expression or measure of habitat 

 differences and of the competitive relations of the various formations. 



Though large for tield use, this book is likely to be preferred 

 to the usual "Manuals" of the flora of the region, by tourists. In 

 general the naraes selected for species are conformed te Neo-Ame- 

 rican practice, but the author's independence of fetters is exemplified 

 in a frankly confessed lack of compunction in correcting improperly 

 formed names or in using short and significant names in preference 

 to long ones without meaning. The sequence of families, following 

 the teaching of Professor Bessey, will be found somew^hat different 

 from that usual in either American or European manuals: — 

 buttercups to mints, then from roses to asters, and from arrow-heads 

 to orchids and grasses, — the conifers frankly out of place, at the 

 end, for reasons of convenience. Trelease.
