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.

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
