mixture, I had to provide more seed because the previous 
stock had been completely exhausted. I procured it in 
the same way, by exchange from botanical gardens, and 
from a similar number of them (about 20). It was not 
to be expected that the identical form of curve would be 
obtained again, because the relative height of the two 
apices obviously depends on the proportion in which the 
two constituent races are mixed; and this must be 
left to chance. I was therefore curious to find out 
whether the 13-rayed race alone was cultivated in some 
gardens and the 21 -rayed exclusively in others. With this 
object I sowed the various samples separately, and on 
a sufficient space to bring as many specimens to flower 
as possible. I then recorded the terminal inflorescence 
of each plant. From no single garden had a pure race 
been sent, neither of the 13-rayed nor of the 21 -rayed 
form. In every case both forms were found mixed and 
in the most diverse proportions. The mixed race was 
therefore the only one generally cultivated at that time. 
The variation in the number of ray-florets in the ter- 
minal inflorescences of the 589 individuals of the whole 
culture of this mixed race from the botanical gardens in 
1895 was as follows: 
L. F. 89 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 
Individuals 73 3 5 14 153 77 60 55 31 33 39 41 56 10 1 1 
That is to say, the same apices as in 1892; but in this 
series the 13-rayed race is obviously more strongly rep- 
resented than the other. 
With a view to discovering also the character of the 
race which is sold as Chrysanthemum segetnm grandi- 
flonun, I sowed a quantity of its seed. When the plants 
flowered in July an extraordinary variety of forms was 
exhibited by the ligulate florets. These were in some
