Gray’s NEw MANvAL OF Borany (Seventh Edition, illustrated). 
A handbook of the flowering plants and ferns of the cen- 
tral and northeastern United States and adjacent Canada, 
rearranged and extensively revised by Benjamin Lincoln 
Robinson, Asa Gray Professor of Systematic Botany in 
Harvard University, and Merritt Lyndon Fernald, Assist- 
ant Professor of Botany in Harvard University. The Amer- 
ican Book Company, New York, Cincinnati, Chicago. 1908. 
Price $2.50. 
The botanists of the United States and Canada are greatly 
indebted to the Gray herbarium on account of this recently is- 
sued work, the most important, with perhaps the exception of 
the first edition, and certainly the best Gray’s Manual ever 
issued. It is an up-to-date book. The authors have not only 
brought to bear an intimate first knowledge gained from study 
of living plants in the field, but have welcomed the assistance 
of others who could contribute this very essential knowledge. 
This is especially true for that part of the territory embraced 
within the limits of the New England States and adjoining 
Canada. 
The geographical limits are not quite the same as in the 
former edition, the western boundary having been changed from 
the rooth to the 96th meridian, while on the north the limit 
has been enlarged so as to include the Canadian provinces of 
Nova Scotia, Prince Edward Island, New Brunswick and the 
greater part of Quebec and Ontario. 
Excellent illustrations accompany many of the descriptions, 
especially in the larger and more difficult genera. All told 
there are 4885 descriptions and 1036 illustrations. 
In the back part of the book is a glossary and a very com- 
plete index of families, genera and species, as well as of common 
names.
