MancH 15, 1909] SYNOPSIS OF ARTOCARPUS 618 
long, heavy, yellowish when mature, the tips of the anthocarps 
pyramidal; the smooth oblong nuts surrounded by a yellowish 
sweet gummy meat. 
This economic tree is the common ‘‘Jack-fruit’’ and extends 
throughout the Philippines. In the hemp fields of the southern 
islands it is especially luxuriant and abundant. In these favor- 
able places it becomes spontaneous and thrives even at 3500 
feet elevation. The natives call it ''Nanka" and its fruit is 
found in all their markets. The gummy meat is sweetish and is 
much relished. 
Originally discovered in the forests of the Western Ghats. 
Now found in eultivation throughout the warmer Pacific islands 
and southeastern Asia.
