This order is well represented here and contains a considerable 
number of important timber trees. There are four genera in the 
Peninsula, viz., Garcinia, Calophyllum, Kayea and Mesua. 
Garcinia. 
There are upwards- of forty species of this genus here, trees 
rarely of any great size, but many attain a height of from forty to 
sixty feet. Several produce eatable fruits such as the Mangosteen. 
(G. mangostana ), Asam Gelugur (G. atroviridis), Mundu (E. dulcis ) 
and Kandis (G. nigrolineata). Nearly all the species produce 
from the bark, when wounded, a quantity of the yellow gum known 
as Gamboge, but in many cases it is scanty in quantity, or only 
partially soluble in water, and often becomes of a dull colour after 
drying. Commercial Gamboge is produced by the Siamese [G, 
morel l a). 
It is imported into Singapore and exported thence to Europe. 
Gamboge is used as a dye, and as a purgative in medicine. 
Some of our wild Garcinias are rich in quantity of Gamboge 
such as G. nigrolineata and it is possible that it might be worth 
collecting. 
G. Mangostana , Mangosteen, Manggis. 
Is usually a short stunted tree but it sometimes grows to a 
height of forty feet. The wood is dark brown, rather hard and 
heavy, with conspicuous rings £ inch apart, pores large in undulat- 
ing lines, and the rays very fine and close. 
Though small this is a fairly good wood for many purposes. 
Pierre says that the wood is much valued for cabinet work, and 
oars. Van Eeden states it is used for building, rice pounders, spear- 
handles, etc.
