epidermis being thinner in the former. This and the absence of 
wax is probably due to the fact that they were not exposed. In all 
respects the seeds resemble those produced by a normal fruit. 
The embryo was found to be present in the several seeds examined, 
and to all appearances, so far as could be ascertained with a hand 
lens, was of normal form and size. 
Some two or three months after finding these specimens, 
another set of intra-ovarial fruits of papaya was supplied to the 
writer through the kindness of Dr. L. O. KuNKEL, of the Hawaiian 
Fic. 5.—Secondary fruits from seed cavity of papaya; slightly reduced 
Sugar Planters’ Experiment Station. These are shown in fig. 5. 
Only two of them are comparable in form and size to those shown 
in fig. 1. These two were rough surfaced, as may be seen from 
the illustration. The lower one of the three middle specimens 
Shown in fig. 5 differed in being turbinate and smooth surfaced. 
In cross-section it was circular, without a seed cavity, but having a 
single vascular bundle near the center. All five fruits in this case

the two larger ones had a placental surface with a few rudimentary 
ovules. The styles of the larger ones were filiform, tipped by a 
very small capitate stigma. An examination of the epidermis of
