 my mind, was one of the most interesting features of the vegeta-

 given consideration to the matter, if they had been asked, but

BOOK REVIEW 

 Trees and Shrubs of Minnesota^ 



This very attractive volume describes all the trees and 

 shrubs knowm as native or naturalized in Minnesota and in 

 addition those frequently cultivated in parks and gardens. 

 While written primarily for those whose interest in plants is 

 general rather than technical, it is interesting to note that 

 the authors have not tried to write down to their public, but 

 expect the public to show enough interest to read the intro- 

 duction, learn a very few botanical terms, and accept accurate 

 descriptions and careful discrimination between species. A 

 good glossary makes this easy for those with no botanical train- 

 ing. The nomenclature follows the International Code as re- 

 vised by the Brussels Congress of 1910. Synonyms are given 

 where other names are used in familiar manuals. 



There is a key to families based on strictly botanical 

 characters, chiefly of the flower, a key to genera based on leaf 

 and stem characters and, under the genera, keys to the species. 

 The descriptions are clear and complete, including botanical 

 characteristics, ranges and habitats, notes on growth, uses or 

 other items of interest. The book is well illustrated with line 

 drawings of fruit and flowers and numerous half tones of whole 

 trees or shrubs or of branches. (A rather amusing error is in 

 using the cut of Riibus parviflortis correctly on the jacket but 

 inverted in the text.) The book is well bound, printed on good 

 quality paper with a complete index. It should prove of real 

 value not only to residents of Minnesota but to those in neigh- 

 boring states.
