minute round scales. The occurrence of these hairs and scales is very in- 
constant. The scales are present in all cases, though there may be but a 
few in some cases. The stellate hairs, on the other hand, are frequently 
wanting and their place may be taken by roughened scurfy patches along 
the under surface of the veins. 
In the circumference of the pith there are 18 to 24 resin-ducts, often 
large and close together. In the petiole, the outer row of 7 to 13 vascular 
bundles forms a closed line, each one containing' a resin-duct. In the 
center is a mass of vascular tissue which is relatively free from resin-ducts. 
Wood white, yellowish or pinkish, no distinction between heartwood 
and sapwood except a slightly darker color in the heart. No distinct 
rings of seasonal growth. Slightly resinous odor when fresh, a sour and 
disagreeable odor if the wood has been left standing in a wet place for 
some time. A wood oil is present in the wood and the vessels containing 
it have often been mistaken for resin ducts. The oil can be secured as 
in Dipterocarpus though it is not commonly collected. • It solidifies 
quickly into a more or less whitish resin. Pith-rays of two sorts, moder- 
ately broad and fine. Vessels of medium size. Wood parenchyma not 
prominent. Wood from young trees coarse-grained, brittle, rather dif- 
ficult to work. Wood from mature trees of very good quality and seems 
to be fairly durable, being used for planks, crossbeams, etc. 
There may be a definite period of leaf -fall ; but, it is not as pronounced 
as in Dipterocarpus. The seeds germinate rather quickly after falling 
to the ground. The fruit is starchy and does not last long. This may 
be due to decay or to destruction by insects or other animals. The young 
seedlings do well in the shade. The flowers are borne in great quantity 
and are yellow. The flowering period for an individual tree is said to 
be not more than one month in length. The flowers are sometimes 
distinctly fragrant. 
There are about fifteen species in the genus. Heretofore, no Philippine 
species has been credited to any region outside the Archipelago. It is, 
however, sufficiently apparent that our Anisoptera thurifera occurs in the 
Malay Peninsula, where it is usually identified as A. glabra , and A. curtisii 
is here reported for the first time from these Islands. This makes 4. 
curtisii the most widely distributed member of the genus. 
This genus in the Philippines gives the extreme northeastern range 
of the family. It also occurs almost as far north in the Philippines as it 
does in Burma.
