PENIOW. 
This is produced by Shorea grandiflora Brandis and is found only in 
Sarawak. It is probably the best member of the family in the region 
where it occurs. In durability, it is considered as second only to billian 
( Eusideroxylon zwageri). Wood very hard, very heavy and very resin- 
ous. More uniformly vellowish-brown than any of the preceding. Used 
for piling, corner posts, wherever great .strength and durability are 
required. 
KAPOR. Plate XXVII, fig. 69. 
Found in Borneo, Sumatra and the Malay Peninsula and some of 
the islands of the Malay Archipelago. The Dutch call it “kampferhout,” 
and the English, “Borneo camphorwood.” Wood reddish, very straight- 
grained. Eesin-ducts not abundant. Pores medium-sized, not fringed, 
and wood parenchyma scanty: Occasionally a faint odor of camphor in 
the wood. Eipple marks occasionally present on longitudinal sections. 
Used for piling, planking, etc. Easily worked and much in demand. 
Produced by the species of the genus Dryobalanops. 
GUI JO (Phil.) ; SAL (Burma); TEIvAM (Sarawak); SELANGAN BATU 
MIREJI (British North Borneo). Plate XXVII, fig. 70. 
In the Philippines, where it is known as a shipbuilding wood, it is 
produced by Sliorea guiso Bl. In Burma it is known as sal and occurs 
in solid stands. It is here the product of Shorea robusta G-aertn. 
Wood hard and moderately heavy to heavy. Wood parenchyma present 
in some quantity, sometimes faintly fringing the vessels and often form- 
ing indistinct concentric lines. Eesin-ducts not infrequent. Grain 
crooked. This is an exceedingly good wood, hut it is very likely to 
warp badly unless carefully seasoned. Used for house and shipbuilding, 
planks, carriage building, etc.

APITONG (Phil.) ; KRUEN (M.) ; ENG (Burma). Plate XXVII, fig. 71. 
Quite a number of species of Dipterocarpus produce wood of this 
grade. The most widely distributed seems to be Dipterocarpus grandi- 
florus Blanco, which is found in the Philippine Islands, in northern 
and western Borneo and on the Malay Peninsula. In the Philippines 
the name apitong is used. In northern and western Borneo and on the 
Malay Peninsula the name kruen is used for the same and related species. 
In east Borneo the name tampoerouw or. tampoedow is found for wood 
which is probably mainly the product of Dipterocarpus tampurau Korth. 
In Burma, th e eng, which is the product of Dipterocarpus tuberculatus 
Eoxb., is a wood of this quality, as is also the wood of Diptero- 
carpus turbinatus Gaertn. f., the gurjun of India, and Dipterocarpus
