134 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
we have not studied the type material, we prefer not to change 
the name 
Although we have had the opportunity to study a few speci- 
mens which were put up in alcohol, our descriptions are based 
on dry herbarium specimens, as is also our key. As a stand- 
ard for color descriptions we have used Ridgway, ‘Color 
Standards and Nomenclature,’ Washington, D. C., 1912. As 
to the citation of specimens, the data given is that received 
with the specimens. The location of all specimens is des- 
ignated by giving in parenthesis the name of the herbarium 
preceded by **in. 
We are indebted to the Missouri Botanical Garden for the 
use of the library and herbarium; to Dr. E. A. Burt for help- 
ful suggestions; to Dr. LeRoy Abrams for the privilege of 
studying Harkness's type; to Mr. S. H. Burnham for his 
eolleetions; to Dr. H. M. Fitzpatriek for specimens from 
New York; to Dr. N. L. Gardner for his collections; to Mr. 
C. G. Lloyd for the privileges of his herbarium; to Dr. W. A. 
Murrill for collections from the New York Botanical Garden 
Herbarium; to Mrs. F. W. Patterson for specimens from the 
Pathologieal Colleetions, Bureau of Plant Industry, United 
States Department of Agriculture; and to Dr. J. R. Weir for 
specimens from Idaho.
