These widely distributed plants are, of course, common enough in 
most of tropical America in their respective habitats. With the ex- 
ception of the sedges, grasses, and ferns, most of the above plants ‘are 
found about the valleys and along the routes of travel. The exceptions 
are made because the groups mentioned require the moisture that is 
found in Margarita only above the valleys in the mountains. 
Excluding both the cultivated plants and those of general tropical 
- distribution, there are left but 524 whose habitat is- restricted to the 
American tropics. Margarita is a continental island, belonging to 
Venezuela. The question naturally arises whether the most of its 
flora pertains to that part of the American tropics or to the West 
Indies. A study of the remainder of the plants makes it very evident 
that the flora still retains its general character in that the majority 
of the species are common both to the West Indies and to South 
America. The exceptions to this are worth noting and areYas fol- 
lows: — 
Common to West Indies. Common to South America.
