’ bagilumbang. Although the extraction of oil from bagilumbang

nuts alone might not be profitable with the present small supply, 
it would probably become so if carried on in connection with the 
extraction of lumbang oil. 
The fertilizing value of the cake of Alewrites trisperma com- 
pares favorably with that of Alewrites moluccana, as will be seen 
from Table 22, taken from Aguilar. e

Planting experiments carried on by the Division of Investiga- 
tion, Bureau of Forestry, at Los Banos showed a germination 
of 98 per cent, germination taking place in nineteen days. At 
the end of the first year the plants had an average height of 
54 centimeters. 
This species, like Aleurites moluccana, was hardy and grew 
rapidly. The average rates of growth of large numbers of trees 
are given in Table 23.

Aleurites trisperma is a tree 10 to 15 meters or more in height. 
It does not have hairs except on the inflorescences. The fruit 
is 5 to 6 centimeters in diameter, somewhat rounded and angled, 
opens later along the angles, and usually has three cells, each of 
which contains a single seed. The seed is somewhat circular, 
flattened, rather smooth, but with numerous small ridges. It 
has a hard, brittle shell about 0.5 millimeter thick. This con- 
tains a white, oily, fleshy kernel consisting of a very thin em- 
bryo surrounded by a large endosperm. This in turn is covered
