III. KKY TO PHILIPPINE CO^niERCIAL WOODS. 
It has l)oen the effort to make this key cover all the woods in the first 
three groups on which the Bureau of Internal Hevemie collects a tax; 
and in addition, such of the fourth-group woods as are commonly found 
on tlie Manila market. Tlie one wood of the first three groups which has 
not been included is malacadios. Specimens of wood bearing this name 
have been received from. several different provinces. These specimens 
represent three or four widely different species. Repeated effort has 
failed to discover here a wood bearing the name of "malacadios;*' al- 
though a number of dealers have said that it is occasionally found in the 
Manila market. We must, for the present, leave this wood out of our 
consideration. -
