In 1916 eight special vines were tested for self-fertility by placing ten 
bags at random on unopened flower clusters of each. The results that 
were obtained in this test are set forth in the following table:

In the two preceding tables we observe at a glance that in many cases 
fruit was produced and obtained without the aid of any cross-pollination. 
Ho such results have ever before been observed or obtained when flowers 
with reflexed stamens were isolated from chances of cross-pollination. 
It will be observed, however, that not all of the vines which were in¬ 
cluded in this test produced fruits in the hags. This, however, is not a 
strange phenomenon when we consider the fact that each one of the 
sixty-four vines was represented by the flowers of only one or two clus¬ 
ters contained in only one hag. Even the eight vines on which ten and 
more clusters were bagged gave evidence that at times no fruits may set 
in some of the bags, and the vines still show signs of self-fertility by 
reason of the fruits that developed in the others. The failure of one or 
all clusters to produce fruit cannot well be regarded as proof of absolute 
sterility. Any one at all familiar with the rotundifolia species knows 
how common it is for young, vigorous vines to shed a great many of the
