PAPAYA CULTURE IN HAWAII

plants of the dioecious type (fig. 14) and the long-fruited or 
monoecious ty r pe. (Fig. 11.) These variations also occasionally 
occur in the Solo strain. (Fig. 17.) 
A peculiar variation of the papaya not uncommonly takes place in 
the formation of small papayas in the true fruit. Sometimes each 
malformed small fruit contains seed and appears to have a stigma, 
but usually it is imperfect in form and seedless. These freaks are 
believed to be due to an overstimulative effect of pollination in 
which more than one ovary is fertilized and abnormal fruits attempt 
to develop in the normal fruit. (Fig. 18.) 
A pistillate-flowered plant of the dioecious type sometimes changes 
the form of a part of its flowers. A number of examples have been 
noted at the station. In one instance a plant produced purely pis-

The flowers are monoc- 
tillate flowers which were followed by smooth, almost-roundish fruit, 
as shown in Figures 1 and 7. A few long-tubed flowers with seem- 
ingly perfect stamens and pistils began to appear among the fruit. 
(Fig. 19.) These flowers were followed by long fruit of the typical 
monoecious type. As the fruiting section of the trunk extended, 
another form of flowers, apparently perfect in most part, developed. 
These were of the kind in which one-half of the stamens, five in 
number, develop to a considerable length and lie in longitudinal 
creases, as shown in Figure 20. These flowers developed short fruit 
with five longitudinal sections or lobes. All three forms of fruit 
were found on the plant at the same time. (Fig. 14.) A somewhat 
similar condition was observed in the Solo papaya. Some of the 
plants produce pyriform fruit, others almost spherical or 5-lobed 
fruit, and occasionally a plant produces both of these forms of fruit 
at the same time. (Fig. 17.) An unusually wide range of difference
