The Solo fruits of the pistillate plants are small but numerous, 
and the yield per plant is considered to be abundant though not equal 
in weight to that of the plants of the larger fruited kinds. The 
Solo fruits weigh from 10 ounces to a pound and are mainly of two 
shapes, pyriform and spherical. (Fig. 12.) The two forms occurred 
separately on different plants for many years at the Hawaii experi- 
ment station, but lately it has not been uncommon to find them more 
or less mixed on the same plant, notwithstanding the fact that the 
seed producing such plants was selected from pyriform fruit. (Fig. 
17.) The skin is smooth and free from blemishes and decaying spots 
which occasionally are found on other kinds of thoroughly ripened 
papayas. The skin is bright yellow to orange in color, and the flesh is

branches are tapering, and fruit and foliage are small 
of medium thickness, rich golden yellow, smooth, tender, and of a 
sweet and cresslike flavor. 
The monoecious or long-fruited type is sometimes called " Elon- 
gata." In general appearance the plant is similar to the pistillate 
plant of the dioecious type, but the inflorescence is usually hermaph- 
roditic, possessing both staminate and pistillate organs. The irregu- 
larities of inflorescence are discussed under Variations, p. 10. The 
inflorescence consists of short flower clusters about 3 to 5 inches long. 
Each cluster is from a separate leaf axil and contains about sit 
almost sessile flowers. The individual flower is iy 2 to 1% inches 
long, and has a tubular base which widens into goblet shape and 
then spreads into five thick, recurved petals of a cream or yellow 
color. (Fig. 13.) The 10 sessile anthers are attached to the throat of 
the corolla near the base of the petals. Usually only 1, 2, or 3 of 
the flowers of a cluster have stigmas sufficiently perfected to receive 
pollen for fertilizing the ovules and thereby developing the elon-
