of this region presents an appearance very similar to that 

 which is usually found in the moist tropics, the rain-forest 

 type being closely approached in places. While forests pre- 

 dominate, there are a few localities in which they are absent 

 or only represented by an occasional tree. In such places the 

 vegetation is made up mostly of bushes and ferns, over which 

 there are tangled masses of lianes, mostly of the herbaceous 

 type. The following list includes the species of plants which 

 are most noticeable in the moist region.

Grassy Region 



This region lies above the moist region, and is characterized 

 by considerable areas covered with perennial grasses, the most 

 common of which is Paspalum conjugatum. Trees are almost 

 entirely absent except in protected places, the probable cause 

 of their absence being the greater velocity of the wind at the 

 higher elevations, combined with a somewhat less amount of 

 precipitation. A number of bushy and shrubby plants are 

 found in this region, the most common of which are Tourne- 

 fortia rufo-sericea and Zanthoxylum Fagara. There are also 

 a considerable number of species of ferns, but it is seldom that
