t f It is known as temiyang in parts of Borneo. The 
species is native to the Malay Peninsula, Sumatra, 
Borneo, and a few of the adjacent islands. Certain 
varieties have been described, and one of these has 
been considered a distinct species — P. oblongifolium 
Burck; but the examination of large amounts of 
material makes it appear that getah taban merah 
is really but one species which has a fair amount 
of natural variation. Other species which produce 
gutta percha of a less valuable sort will be men- 
tioned under inferior guttas. 
The term getah is a Malay word for a sticky 
gum, and pertja is said to be the Malay name for one 
of the less valuable guttas and also for the Island 
of Sumatra. The term gutta percha therefore may 
be a corruption of the original native names, or may 
merely mean Sumatra gutta. 
3. Method of Production of Gutta in the Tree. 
All of the different forms produce their gutta in 
the same way. There are no long laticiferous tubes 
in the bark, but, instead, a large number of irregular 
cavities, sacs, or intercellular spaces, which are not 
connected up for long distances through the bark, 
as is the case with laticiferous tubes. Consequently, 
tapping cannot be done, as in Para rubber, by one 
or a few cuts. Cavities containing gutta are also 
found in the leaves and pith, but not in the wood.

Palaquium Gutta Burck . 
Medium-sized trees of the second storey in the 
forest. Trees more than one hundred feet in height 
and ten feet in girth are said to be sometimes found, 
but are certainly very rare. Trees much more than
