Retnarks. — Of these seventy plants there is not one that has not come 

 within the scope of my observations and experiments. The West Coast of 

 Africa is included in the American region for reasons given in Chapter 

 VIII. For the other authorities on the buoyancy of these seeds and fruits 

 reference should be made to the list given under Note 2 and to other parts 

 of this work. About one or two of the plants, like Ipomea peltata, one 

 scarcely knows whether they are most characteristic of the coast-flora 

 or of the inland-flora.

 FEW Species, with the Assistance of Frugivorous Birds 



Coluhrina asiatica. — Usually regarded as confined to the Old A\'orld ; 

 but since nearly all the species are American, that continent may be 

 considered as the probable home also of this species. Hillebrand gives it 

 a locaUty in the West Indies. 



Dioclea violacea. — Tropical America. 



Mucuna gigantea. — Old World, 



Mucuna urens. — America, and extending to the African West Coast, 

 which is to be included in the American region of shore-plants.
