as large, I he wood is heavier and more compact with distinct 
rings, small numerous pores, and tine but unequal rays joined hv 
transverse bars like the wood of Baccaitrea . Weight 51 lbs. It is 
a better wood than that of the two previous ones and is used for 
planks, beams etc. 
Trema amboinensis , Bl. Narong. 
. A sh ™ b hardly a tree with soft and light pale reddish wood 
rings fairly distinct, rays narrow unequal and rather distant. 
Common in secondary growths and thickets. This wood is oniv 
used as firewood here, byt in India and Ceylon is valued to make 
charcoal for gunpowder and fireworks. It 'appears to be a bigger 
plant in India and of rapid growth. Gamble mentions a tree which 
grew 25 feet in five years with a girth of 40 inches and gives the 
weight at 28 lbs. per cubic foot, S. 24-28. He says it may be used 
in plantations to keep down grass jungle and is used to shade 
coffee. Here through rapid in growth it usually stops soon only- 
attaining a height of 12 or 15 feet. The bark gives a fibre used in 
India. 
A ntiaris toxicaria, Bl. Ipoh or Upas d ree. 
A tree of vast size with thick bark and white soft wood. It is 
well known for its poisonous latex used in the Sakai dart poison. 
Weight 37 lbs. 2 ozs. 1 
Sloetia sideroxylon , Teysm. Tampinis. 
1 his valuable tree occurs all over the Peninsula and in the Rhio 
Archipelago. 
■f attains a height of 60 to 80 feet, trees of that size are now- 
rare. It has small dark green lanceolate rather papery leaves, the 
ma e flow ers in a yellow catkin, at the base of which are one or 
more female flowers which are larger and green. The fruit, is white, 
and the succulent surrounded by two swollen white sweet sepals' 
which by pressure eventually eject it. The twigs and leaf stalks 
contain a small amount of w hite latex. 
1 he timber is one of the best in the Peninsula, being hard and 
durable, attacked neither by white ants nor by fungi. The sapwood 
is light coloured yellowish white, the heartwood dark red. Though 
there is usually a considerable amount of sapwood, yet even that 
is hard and good and appears to be what the Malays know as 
Tampinis putih. When fresh cut the tree exhales a peculiar strong 
odour. The heartwood is dark brown or red brown with irregular 
darker rings broad and distant, pores in rows numerous smalTand 
containing a resinous matter, rays very fine much finer than the 
pores. 
Newton gives its weight as 61-41 lbs. per cubic foot. Specimens 
from Singapore weigh 54 lbs. 6 ozs. to 78 lbs., from Lingga 70 lbs. 
5 ozs. 
Newton says that it shows the greatest strength of any wood he 
examined (1,732 lbs. being given as its breaking weight, against 
1,529 lbs. in Darn, the next highest) but it appears to lie deficient
