184 COLONIAL KEPOBTS MISCELLANEOUS. 



Each of the above species has within its distributional range a 

 particular area or series of areas in which it is at its optimum and 

 aggressively dominant. 



As a general rule the undergrowth in the drier portions of the 

 monsoon forests is less dense than it is in the case of the rain 

 forests, and the number of tiers of vegetation is also reduced. 



The more valuable economic species to be met with in the mon- 

 soon forests may be arranged as shown below. 



(a.) Species yielding first-class timber fit for export. 

 i. Mahoganies 



The white mahogany (Khaya anthotheca). 

 The large-leafed mahogany (Kliaya grandis).
