Swietenia M ahogatii, E- 
Mahogany lias been planted experimentally in several parts of 
the Peninsula. It is very slow of growth at first at least her , 
and is apt to branch a good deal. 
S. mactophylla. 
Grows better and more rapidly. It has been planted experi- 
mentally of late years and evidently does better here an 
small leaved mahogany. 
OLACINE^E. 
This order contains two of our most useful first class timbers, 
viz Petaling and Kulim. 
Ochanostachys anientacea , Mast. Petaling. 
A tree of no great size usually about thirty or forty feet tall and 
a foot through. The bark thin and flaking off in rounded flakes, 
brown. The foliage reminds one of that of the English beech, the 
foliage being dense elliptic and shining deep green. 1 he flowers 
very small green in short racemes, and the fruit an oval green 
milky drupe with one large seed. . , . 
The tree occurs in jungle all over the Peninsula and is quite 
common. If cut down it shoots up again from the old stool. Uke 
most hard woods it is of slow growth, and it is not easy to ge 
good seed of, as apparently many of the fruits fall unfertilized. 
There is very little sap wood, the whole of the tree being usable 
as a hard wood timber. The wood is hard and heavy, deep brown 
becoming lighter coloured by exposure. The rings are fine and 
close and wavy, the rays exceedingly fine and numerous and very 
close. The pores are arranged in short lines, four or five toget icr. 
Though Petaling is by no means as large a tree as many ot our 
best hard woods, many trees are quite large enough for almost all 
purposes. The timber is very durable, not difficult to work and 
proof against white-ants. For house work it is excellent and 
attempts have been made to use it for railway sleepers, but it is 
said to be liable to split in the sun. 
Scorodocarpus Borneensis , Becc.. Kulim. 
Is a tall tree with rather flaky bark, about 60 feet tall, and i£ to 
2 feet through. , . 
The flowers which are of' moderate size are white, the fruit a 
large drupe about an inch through, green with a thin pulp, and a 
large stone. 
The strono- odour of onions which every part ol the tree gives 
out, including the wood when fresh makes the Kulim easily identi- 
fiable. It occurs in jungle all over the Peninsula and is ig y 
prized as a first class timber. The wood is resinous, deep brown 
in colour, heavy and fairly hard. The pores are arranged m lines 
and are small and usually full of resin giving the wood a peculiar 
shining appearance, especially in longitudinal section where the 
vessels are seen to be full of the resin. The rays are very fine 
and cloge, the rings narrow and wavy. In appearance Kulim re-
