often troublesome, though not seriously injurious. Red 
ants (herengga or kelanghrang), Oecophylla smaragdina 
(Grist, l.c.), are probably the greatest pests. They make 
their nests among the branches by drawing a number of 
leaves together. The only way to destroy these insects 
is by burning their nests. 
Fungous diseases, which infect the leaves or fruits and 
other microorganisms living in the roots and which may 
cause the death of the plants have not as yet been studied. 
MARKETING OF RAMBAI AND KAPUNDUNG 
The rambai and hapundung fruits are produced mostly 
in villages, valleys, and foothills, localities relatively far 
from the markets. In season, the fruits are produced in 
great abundance. The rambai season in Malaya falls be- 
tween August and September (Macmillan, 1949); in 
Java, tne hapundung season is between January and 
March (Ochse, 1931). The fruits are collected before 
they are completely ripe on the tree—that is, when they 
turn yellowish or brownish. They are picked from the 
tree in bunches, put into baskets and taken directly by 
the owner to market for sale. In this case, the price is 
usually low. But very often the fruits are disposed of at 
roadside to traveling dealers or sold directly to the cus- 
tomers. Selling the fruits while they are still on the tree, 
a practice known as 7zdjon, as with durian (Durio Zibeth- 
inus), rambutan (Nephelium lappaceum), and langsat 
(Lansium domesticum), is very rarely or never practiced 
with rambai and kapundung. Since there is no attempt 
to increase yield of the fruit, the unit of production is 
too small to allow good prices to be obtained; but in the 
case of roadside sales, this factor is sometimes overcome 
by the owners’ arranging to take their produce to a defi- 
nite place on a particular date, thereby obviating the 
necessity for a dealer to visit several places before ob-
