THE AMERICAN BOTANIST 



species that need to be backed up by copious descriptive matter, 

 but here every species is singled out by some saHent character- 

 istic and no further description being needed, none is given. 

 The book is also unique in departing in many ways from the 

 accepted classification as illustrated in recent manuals, begin- 

 ning, for instance, with buttercups and running into the mints 

 before taking up such primitive families as the roses or arrow- 

 heads. There are twenty-five excellent plates in color by Mrs. 

 Clements as well as some hundreds of figures in black-and- 

 white and the text covers nearly 400 octavo pages. The ar- 

 rangement of the type could have been improved by the selec- 

 tion of faces of greater contrast, but this defect is not likely to 

 greatly bother those who consult the book. The area covered 

 by the work is practical^ that of the Rocky Mountains in the 

 United States and contiguous territory. The book is published 

 by the H. W. Wilson Company of White Plains, N. Y., at 

 $3.00.
