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 are as fol- 

 lows : —
