Summary-. All the plants in the above' list do not have 

 exactly the same habitat, for the amount of shade and moisture 

 varies on different bluffs and on different parts of the same 

 bluff ; but the differences in habitat are probably not great enough 

 to introduce any serious error into the generalizations which 

 follow. 



This flora is comparable only with that of the hammocks just 

 discussed. Just about one- third of the species on the bluffs are 

 common to the hammocks, as far as known, and future discov- 

 eries probably will not change this proportion much. 



Woody plants are more numerous than herbs, as in the ham- 

 mocks, but on the bluffs, unlike the hammocks, evergreens are 

 in the minority. Vines are quite numerous, and there are a few
