lu 1898 and again in 1900 I noted the flowers of place C in several different lots as I worked 
my way down fi'om the upper to the lower end of the strip of copse. In 1898 the lots from 
the ui)per end exhibited a large excess of sixes, the lots from the lower end an excess of sevens : 
in 1900 there was an excess of sevens in both cases. Has the race at the top been swamped by 
a race from the lower end of the copse ? I do not think it very likely, as 1899 shows no sign 
of such a process. The actual figures from my notes are as follows :

I hope to be able to continue these observations, and have merely i>ut these notes together 
to illustrate the fact that a " local race " must be observ ed for, at least, some years before its 
characteristics as compared with other races can be known. All jjlants may not fluctuate so 
much as these Anemones but it cannot be assumed that they do not. 
Variation in the Ray-flowers of Chrysanthemum leucanthemum L. at 
Yellow Springs, Greene Co., O., with remarks upon the Determina- 
tion of Modes. 
By W. L. tower, Yellow Springs, Ohio. 
[Received November 11, 1901.] 
At Yellow Springs, Greene Co., 0., Chrysanthemum leucanthemum L. occurs in only two 
localities, one and one-half miles apart. Between these localities are cultivated fields and 
woodlands, and except in these two spots this species is not known to occur within five miles 
of Yellow Springs. So considerable a degree of isolation for this species is uncommon in the 
eastern United States, and aftbrds a good opportunity to determine whether it has produced any 
change in the modes, — 8, 13, 21, 34, — as they have been determined by Ludwig (1895, 1896 a, b, 
1898 a, b) in Germany.
