is true of the intermediate seeds with the exception of 
four, two of which were abnormal. 22 normal plantlets 
developed from the smallest seeds in the same time ; the 
9 other normal and the 25 abnormal ones did not unfold 
their first leaf until the third week. 1 
These facts show further that the number of seed- 
lings with abnormal primary leaves does not depend 
simply on the degree of fixation of the variety. It de- 
pends mainly on the proportion of small seeds. This, 
however, in its turn, depends on the size of the harvest.

primary leaves ; C, with a double leaf with broad

In the 41 samples which composed the harvest of 1898 
there were 8 with 8-27% abnormals; these samples con- 
sisted of from 0.3 to 1.5 cc. of seed. The remaining 
samples consisted of from 2 to 5 cc. of seed and the 
number of abnormals produced ranged between and 
5%. From these facts we see that the weaker individ- 
1 In stocks also the seeds which produce plants with double 
flowers and those which give rise to "singles" have different rates 
of germination, as is well known. An investigation of the seeds of 
inconstant varieties, or, as they are usually described, varieties which 
have not "yet" been fixed, would be certain to reward the inquirer 
with many interesting discoveries.
