MUHLENBERGIA 
STUDIES IN TRIFOLIUM—VII 
By P. BEVERIDGE KENNEDY 
Some time has elapsed since our last paper of this series 
was published in Muhlenbergia. Since then we have had the 
privilege of studying for several months at the herbarium of the 
Royal Botanic Gardens, Kew, London, while on sabbatical leave 
from the University of Nevada. Ourattention in the herbarium 
was given exclusively to the clovers, and copious notes were 
taken from the types of American species. 
The publication of Miss L. F. McDermott’s book entitled 
“North American Trifoliums,” under the supervision of Profes- 
sor Jepson, of the University of California, led us to believe that 
a satisfactory treatment of the genus could not be made by a 
study of herbarium specimens alone, but that the different spe- 
cies would have to be watched from the seed to maturity. This 
feature of the work is now in progress both in the field and 
greenhouse, and a number of new and interesting observations 
have been made. 
Drawings of each species have been made under our direct 
supervision by Mr. L. T. Shannon, a student in the University. 
They are very complete and accurate, and consist of a drawing 
of the entire plant; a seedling; the variations in the shape of the 
leaflets within the species; a floret in full bloom; a floret just 
after blooming; the calyx tube and teeth spread out; the vexil- 
lum; the legume and the seed These illustrations will not be 
used until the monograph is completed for publication. 
Our present paper includes a general discussion of the Mac- 
raei group, a correction of the errors of previous workers on Tri- 
folium, complete descriptions, which in many cases were so
