BOOK REVIEW 

 " The Moss Flora of New York City and Vicinity " 



By A. J. Grout, Ph. D. 



This interesting volume of 119 printed pages and 12 plates of photographic 

 reproductions of some 20 species, is in the announcement designated as an "an- 

 notated list." The modesty of the author is the only explanation for this desig- 

 nation; for it is far more. It will serve very well as a true handbook for studying 

 the mosses of the environs of New York City. The descriptions of families 

 and genera, and the excellent keys to genera and species, with many independent 

 and practically tried diagnostic characters, will prove helpful and inspiring to 

 amateurs and even to professional students. In the genus Sphagnum on\y, the 

 author states, the list and key are "frankly a compilation."
