pistils (see Fig. 13, and Plate II, Figs. 1-3). In fact, many pistillate 
rudiments in flowers on staminate vines are larger than many similar 
rudiments in flowers on hermaphrodite vines. With this variation of 
the pistils in mind, it is not difficult to imagine that by a sudden release 
from an inhibiting factor these pistils, so long' suppressed, have sud¬ 
denly grown out and become functional. 
Fig. 14.—Variations in size of the pistils frequently found on the hermaphrodite seedlings 
of Hope which hear the upright stamens. Cluster on the left represents the normal 
type of pistil, while cluster on the right shows considerable reduction in size of the 
pistils. Natural size.
