PAPAYA CULTURE IN HAWAII 
fied it with the families Passifloreae, Cucurbitaceae, and Papayaceae, 
and by some authorities it is still placed in the last-mentioned group. 
A number of other related species of Carica grow mainly in the 
wild state in different parts of the Tropics. None of them, even 
under cultivation, 
produces fruit which 
compares with that 
of Carica papaya, 
but they may prove 
to be of value in 
papaya - breeding 
experiments. 
C. candamarcensis, 
the mountain pa- 
paya of Colombia 
and Ecuador, is de- 
scribed by Popenoe 
(16, p. 240) and bv 
Wilcox (U, V- 119) 
as a small tree with 
cordate, palmately 5- 
1 o b e d leaves and 
sma 11 yellow 5 - 
angled fruits about 
3 or 4 inches in 
length. In flavor 
the fruit is too acid 
to be used as a des- 
sert, but it may be 
stewed or made into 
jam and preserves. 
C . can dama rce n sis 
is also described and 
illustrated by Mac- 
millan (14, p. 274- 
275). 
The plant of C. 
erythrocarpa is simi- 
lar to that of the pa- 
paya, but the fruit 
has thin red flesh, 
which has sometimes been considered as particularly useful in the 
production of papain (24, p. 110). 
C. quercifolia attains a height of about 5 or 6 feet and has oaklike 
leaves and clusters of small yellow ellipsoid fruit 1 to 2 inches long 
with five longitudinal stripes that change from white to yellow as it 
ripens. 
C. gracilis is a small, slender, ornamental from Brazil. It has 
compound leaves, 5-digitate, each leaflet having wavy indentations, 
the middle leaflet being 3-lobed (/, p. 664). 
DESCRIPTION 
At least two leading type- must he taken into consideration in a 
general description of the papaya. These are based upon such
