ti net and often very broad about 15 to an inch, the pores are large 
and few scattered, the rays waved rather conspicuous and much 
broken up, 
, Rather an ornamental wood, the rings of darker coloured wood 
alternating with softer paler tissue. Weight 2ylbs. to 37tbs. 8 ozs. 
M. Kemanga, Bl. Kemang. 
A vast tree, with a perfectly straight stem and a large crown of 
foliage. 
The wood is pinkish in colour turning brown with age and has 
the same few large pores and distinct rather distant rings of 
M. Coesia, but the rays are more obscure. It appears to be a 
better class of wood being more compact and firmer. The resin is 
acrid and injurious to cutters, like that of the Rengas. Weight 32 
lbs. 10 ozs. 
M. sp , M'bachang hutan, Medangkok. 
This appears to be some species of nmngifera, but from what 
tree it is obtained is not known. Its timber is not very hard but 
is valued lor planking, boxes, etc. It is of a bright canary yellow 
when fresh becoming brown after exposure. It has rather large 
scanty pores two or three together, the rays are fine and the rings 
usually indistinct. It is rather a light wood. Weight Selangor

Melannorhea Maingayi , Hook fil. Rengas Manau, Straits Mahogany. 
Avery large tree with white flowers and curious red fruit with five 
winglike petals. The name Rengas is applied to a number of 
allied plants, besides the Melannorheas of which there are here, 7 
species, the various species of Gluta and Parishias being also called 
Rengas. Tlie timber known as Rengas in trade here is, however, 
M. Maingayi, It is common all over the south of the Peninsula 
and in Sumatra, but in the north is replaced by M. Curtisii , which 
has smaller fruit with narrower wings. 
The tree has a considerable proportion of soft yellowish white 
sapwood, the heartwood is heavy and fairly hard dark red in 
colour of rather coarse texture, with distinct often broad darker 
coloured rings sometimes nearly black, the pores are large and 
scattered not numerous, the rays very fine and obscure. In young 
wood and sapwood the pores are encircled by lighter coloured 
tissue. 
The wood is very handsome and valued for furniture building, 
etc. It has the disadvantage, however, of possessing much of the 
black caustic resin which is very poisonous, and gives rise to what 
is known as Rengas poisoning in those who cut the tree, and the 
same effects are said to be produced in many persons by use of 
furniture made from it, even long after the wood has been worked 
up. For beams it is durable and not attacked by termites. Indeed 
it is common after felling the tree to leave it lying in the jungle 
till the sapwood is destroyed by termites and decay when the 
hard and durable heartwood is uninjured by them.
