It will thus be seen that, exclusive of correae, approximately 94 
per cent of the trees are fruit bearing. This is an encouraging result, 
so far as the elimination of the males is concerned. It is not prob- 
able that the 61 designated as elongata will continue to produce 
flowers and fruits of this form exclusively. It is probable that some 
of the pentandria form of flowers and fruits will appear, but it is 
hoped that it will be possible to develop a pure strain of uniform 
shape. It is probable that the progeny will continue to include 
pistillate as well as hermaphrodite trees. Whether it will be neces- 
sary to have two forms of a variety, one borne on the pistillate tree 
and another on the hermaphrodite, can not be determined at present. 
If this should be the case, it would necessitate, in marketing, two 
packs, which might be sold under different varietal names. This 
will be no serious disadvantage, provided uniformity can be main- 
tained in each form. There are two ways, however, in which it is 
conceivable that a uniformity might be maintained, common to the 
hermaphrodite and the pistillate alike. Among the pistillate trees 
of No. 3198 were several with elongated cylindrical ovaries, like 
those found on the hermaphrodite elongata, which would indicate 
that this particular shape of ovary and resulting fruit is not necessa- 
rily confined to hermaphrodites. 
Another conceivable means of establishing uniformity would be in 
the selection of pistillate trees whose fruits are angular like those of 
the hermaphrodite pentandria. 
HERMAPHRODITISM IN LYCHNIS DIOICA. 
In this connection the experiments of Shull 1 on Lychnis dioica are 
interesting and important. Hermaphrodite individuals appear as 
mutants in L. dioica. These the author concludes are modified males 
and are of two kinds, distinguished as "genetic" and "somatic" 
hermaphrodites. 
"When the genetic hermaphrodites are used as pollen parents, either when self- 
fertilized or in crosses with females, their progeny consists of females and hermaphro- 
dites. When they are used as pistil parents and fertilized by normal males, they 
produce females and normal males. 
Somatic hermaphrodites may be externally indistinguishable from genetic her- 
maphrodites, but when used as pollen parents they produce no hermaphrodite off- 
spring, but only females and normal males. 
These somatic hermaphrodites, however, were found to be rare in 
comparison to the genetic hermaphrodites. The author has shown
