Brown and Mathews: Dipterocarp Forests 



1427 



From Table II it may be seen that although, exclusive of 

 seedlings under 10 centimeters in diameter, there are nearly 

 as many individuals of dipterocarps below 40 centimeters in 

 diameter as there are above, nevertheless, the great bulk of 

 the forest in regard to volume is distributed among the larger 

 trees. Furthermore, the same fact holds true in regard to the 

 distribution of the canopy. The main canopy of the forest is 

 that of the standards and veterans, and this is an entirely 

 closed canopy. The trees of as small diameters as 40 centi- 

 meters have their crowns overtopped by the crowns of the 

 main overmature stand, and, as a consequence, these trees are 

 poorly developed, slender poles with suppressed cro\vns. When
