the three islands which grow in the whole of tropical America 

 and 113 which are also found in the Old World. 



The following list shows the numerical distribution of the species, 

 occurring in the three islands, over the principal families. For 

 comparison also the numbers for Margarita have been given; the 

 numbers of plants, occurring in the Dutch Islands as well as on 

 Margarita, are placed between brackets. 



From this list and still more from the Systematical Part itself

 are only represented by a single genus and often by only one 

 species and that, on the whole, only a few genera occur with a 

 large number of species. 



The number of species, found on each of the three islands, is 

 given in the following list.
