May, 1923] VALLEAU-INHERITANCE IN THE STRAWBERRY 263 
Hermaphrodite X Hermaphrodite 
The cross hermaphrodite X hermaphrodite should give the same results 
as to sex types as hermaphrodite X self. The results of 11 such crosses 
are given in table 2.

* Stamens of intermediate type between staminodes and perfect stamens. 
These results are similar to those obtained by selfing hermaphrodites, 
with the exception of one cross which gave apparently a 1 : 1 ratio of 
hermaphrodites and pistillates. These were the progeny of a cross in which 
an hermaphroditic Fi seedling of F. virginiana $ X 778 § was used as the 
female parent and Glenville as the male parent. According to our hypoth¬ 
esis, the female parent (hermaphrodite) derived from F. virginiana $ X 778 
should be of the constitution MH , the M representing the male determiner 
carried by a wild female. Glenville we may consider to be HH. From 
such a cross all the progeny should be hermaphrodites at least as far as 
somatic condition is concerned. It seems probable that this was the case 
in view of the stamen condition found in a portion of the flowers in other 
combinations in which 778 was used. When 778 was selfed it produced 
only hermaphrodites. Some of these developed stamens which produced 
only a small amount of pollen in some flowers while the stamens of other 
flowers were practically identical with the staminodes of pistillate plants. 
One of these clones was used as the female parent in a cross with Glenville 
(table 2, 53/16). This cross produced 67 hermaphrodites. Forty-seven of 
these developed normal stamens in all the flowers. Twenty showed a 
decided tendency toward the production of staminodes similar to those 
found in pistillate flowers or of the intermediate type found in their female 
(hermaphroditic) parent. Eleven of the twenty bore flowers which pro-
