If there be no relationship between the number of flowers per 
inflorescence and the position of the fruits on the inflorescence, one 
should find a linear relationship between the average position of 
the fruits and the number of flowers per inflorescence. Тһе equa- 
tions to the straight lines in 4 of the series are: 
Meramec Highlands, 1906, 300 inflorescences, 2017 fruits 
р = — .554747 + .482806 
Jefferson mee 1906, 1250 inflorescences, 6481 fruits 
= — 400325 + .472802 f 
Meramec Highlands 1907, 605 inflorescences, 3586 fruits 
— .857833 + .512934 
Jefferson сал 1907, 1270 inflorescences, 7926 fruits 
= + .160829 + .447496 f 
The lines and pe іга means for the 1906 series appear in 
.8. Тһе results indicate sensible linearity. 
Turning to the problem of the correlation between number of 
flowers per inflorescence and deviation of position of fruits from 
its probable value, we note that the values are low throughout. 
They are generally smaller than their probable errors. Thus they 
indicate that the number of flowers per inflorescence has practi- 
cally no influence on the position of the fruits which develop to 
maturity.
