128 ROSACEAE. 
The most sumptuous American publication on Prunus is 
contained in Hedrick’s large volumes on The Cherries of 
New York and The Plums of New York. Critical analysis of 
our native species of Prunus and of the varieties of plums 
derived from American species, by Wight, constitute respect- 
ively Bulletins 179 and 172 of the United States Department 
of Agriculture,—both published in 1915. An analysis of the 
pubescent-fruited species of the Southwest is published by 
Mason in the first volume of the Journal of Agricultural Re- 
search, issued by the Department of Agriculture. Some of 
Professor Bailey’s earlier opinions on Japanese plums were 
published in Bulletins 62, 106, and 139 of the Agricultural 
Experiment Station at Cornell University.
