is ovoid, and 5 to 6 centimeters long. It contains one or 
two hard-shelled seeds. The seed is about 3 centimeters long 
and 2.5 centimeters broad. It has a hard, rough, ridged shell 
about 2.5 millimeters thick. This contains a white, oily, fleshy 
kernel consisting of a very thin embryo surrounded by a large 
endosperm. This is in turn covered by a thin, white, papery 
seed coat. This thin seed coat adheres firmly to both the shell 
and the kernel, so that the kernel is separated from the shell 
with difficulty. 
This species is distributed from Luzon to Mindanao and Pa- 
lawan, and recently has been planted in great numbers in Cebu.

ALEURITES TRISPERMA Blanco. (Fig. 46). BAGILUMBANG. 
Local names: Bagilumbdng, balukandd (Laguna); banukalég, lumbang- 
banukalad, lumbang-gubat (Cavite); balukandg (Batangas); lwmbdng 
(Oriental Negros, Camarines). Also reported from Rizal, Tayabas and 
Davao. 
BAGILUMBANG OIL 
As previously mentioned, oil extracted from the nuts of Aleu- 
rites trisperma has characteristics which are almost indistin- 
guishable from those of Chinese wood oil or tung oil. 
According to Heyne* Aleurites cordata R. Br., until recently 
and erroneously believed to be a source of wood oil, occurs in 
southern Japan. The constants of this oil are remarkably like 
those of bagilumbang oil from Aleurites trisperma. 
The shells of Aleurites trisperma are much more easily cracked 
than those of Aleurites moluccana. Moreover, the kernel is not 
so difficult to separate from the shell because, when the nut is 
dry, the kernel shrinks somewhat and may be easily removed 
after the nuts have been cracked. Richmond and del Rosario + 
found that one kilo of whole nuts contained 357 grams of shells* 
and 643 grams of kernels. 
The oil from the nuts of Alewrites trisperma deteriorates when 
the nuts are stored. Moreover, according to Aguilar, the oil 
deteriorates also if not kept in an hermetically sealed container. 
Aguilar says that the yield of oil by expression at 800 kilo- 
grams per square centimeter may reach as high as 56 per cent 
of the weight of the kernels. Oil prepared from fresh nuts is 
of very good quality and light amber in color. The constants 
of bagilumbang oil have been determined by Richmond and Ro-
