piled mainly from the field notes of forest officers, 
of some of the more important of the rattans of 
the Malay Peninsula.

This, the best of all the rattans, is rather slender 
and high climbing, flexible, strong, and easy to 
work. It occurs in quite a variety of soil conditions, 
sometimes in the clay soil of upland forest and 
sometimes in the sandy Soil of river banks, but it 
is said not to thrive in fresh water swamp. It 
occurs naturally in the Malay Peninsula, Sumatra, 
Borneo, and some of the other islands of the Malay 
Archipelago. It has been collected for many years, 
until the natural supply has become small. The wild 
supply is now supplemented by material from plan- 
tations in the Malay Peninsula, Borneo, and Sumatra. 
The plantations in the Malay Peninsula are small, 
but are found in most of the States. The planted 
rattan is said to bear fruit within 5 or 6 years and 
some of it may be harvested soon after, but it is . 
not commercially mature till 10 or 15 years old. 
A full grown clump may have from 100 to 150 or 
more climbing stems, wdiich may attain a length of 
100 to 120 feet or more. In one case 156 stems 
were counted from one clump. This rattan is used 
locally in the manufacture of mats, chair seats, 
fancy baskets, and for certain kinds of weaving. 
It is used in Europe for chair seats, etc. 
The stems are unbranched. When very young 
they are covered by the spiny leaf sheaths, and when 
mature they have a more or less waxy glaze and are 
0,2 — 0.6 inch in diameter. The length of internodes 
is 7 to 14 inches and the nodes are very little
