VEGETATION OF SOUTH FLORIDA

A number of families not included in the Miami flora are found in the 
manual of the Florida keys, viz., Hippocrateaceae, Canellaceae and Clusi- 
aceae. The families that would not be represented in the Miami flora but 
for the fact that they are families of introduced plants are Convallariaceae, 
Musaceae, Alpiniaceae, Casuarinaceae, Basellaceae, Caryophyllaceae, Papa- 
veraceae, Sedaceae, Papayaceae, Punicaceae and Plantaginaceae. The 
introduced families correspond exactly in the two regions of South Florida. 
That the flora of both the Miami region and that of the Florida keys is a 
chopped-up one is shown by the fact that there are 52 families out of 146 in 
the Miami flora with only one genus and one species, according to Small’s 
interpretation of family limits. But for the presence of this one species, about 
one-third of the families would be absent entirely. In the Flora of the 
Florida Keys, 38 families have but one genus and one species. If we include 
those families of one genus and two species in each such genus, the number in 
the Miami flora is augmented by 8 families and in that of the Florida keys by 
6 families. The big families of the Miami flora are in the order of their im- 
portance.
