While all the trees mentioned above may in exceptional cases reach 
a diameter limit of 30 centimeters, as a matter of fact most of them will 
reach when mature not over 40 centimeters in diameter and very few of 
them have the power to reach the diameter and height of some of the 
dipteroearps. 
If bulk were taken into consideration the proportion of the dipteroearps 
would be much greater. This will be shown in another connection. 
The 334 remaining trees that can not reach, when mature, 30 centi- 
meters in diameter will not average over 15 centimeters in diameter. 
Strange to say, while 40 species are represented in these, the vast 
majority of them are distributed among species of the Euphorbiaceae and 
Melastomataceae. Thus Memecylon edule Eoxb. (Melastomataceae) is 
represented by 94 trees, and Aporosa sphaeridophora Merr. by 81, Cyclos- 
temon micropliyllum Merr. by 30, Aporosa symplocosifolia Merr. by 22, 
and Baccaurea tetrandra Baill. b}^ 10. The last four named belong to 
the Euphorbiaceae. 
It might be argued that plots adjoining the one given above might 
greatly increase the number of species. While this is true to a certain 
extent, yet the possibilities are not great when it is known that on the 
Larnao Forest Reserve comprising 4,426 hectares and ranging in altitude 
from sea level to 1,406 meters there have been listed so far 548 tree 
species. This covers the trees of all habitats from those where introduced 
tree species are found to the mossy forests on top of the highest peaks. 
It is to be expected that the variety of habitats thus represented would 
bring about a variety in tree species peculiar to those habitats. Thus 
beach and mangrove habitats show distinct sets, river bottoms others, the 
mossy forest and various types of dipterocarp forest still others. It 
should be noted here that all eight of the dipteroearps found on the 
Lamao Forest Reserve of 4,426 hectares are also found on the plot given 
above comprising less than one hectare. At the time I wrote the “Vegeta- 
tion of the Lamao Forest Reserve” the significance of the above did not
