the temporary disappearance of the hermaphrodite character 
through some thinkable vagary of dominance in the F,, 5 males 
in 08125 were tested in crosses with 2 different females. The 
resultant progenies consisted of 333 females and 168 males. Not 
a single hermaphrodite appeared, thus convincingly supporting

the view that the appearance of hermaphroditism in C and D was 
illusive, and that they were therefore only superficially like the 
genetic hermaphrodites A and B. These results fully justify my 
conclusion that the hermaphrodites of Lychnis dioica belong to 
two genotypes, one of which is the same as the normal male, the 
other different from it. 
Discussion and conclusions 
Although these data from the breeding of hermaphrodites of 
Lychnis dioica are presented in fourteen sections, each represenUng 
a somewhat different direction of attack upon the genetic problems 
involved, the results under the various sections are remarkably 
consistent. The hermaphrodites are clearly of two kinds. Those
