Correlation between Somatic Characters and Fertility 
Hibiscus trionum, L. 
The three preceding species are tall-growing native perennials. H. trionum is 
an adventitious herb, widely disseminated in the Eastern United States — some- 
times a rather serious weed.

As material I have 169 fruits taken from a large number of plants growing in 
a very poor weed-infested pasture near Mt. Hermon, Athens Co., Ohio, in the fall 
of 1907. The data are given in Tables IV — V, and the constants for number of 
bracts and ovules and seeds per locule are : 
M b = 11-225 + -053, a b = 1-024 ± -038, V b = 9-129, 
M 0 = 7-857 ± -032, a 0 = 1-374 + -023, V„ = 17-491, 
M s = 7-058 + -037, a s = 1-589 ± -026, V s = 22-576, 
for bracts and ovules r = -186 + '050, r/Er = 3 51, 
for bracts and seeds r = -106 + "051, r/Er = 2-08. 
These values are both low, but possibly the first is significant.
