As to the origin of these 40 species, it is difficult to say which have origi- 

 nated in the United States and which in the Bahamas. Eragrostis elliotti 

 S. Wats., Thrinax floridana Sarg., Pseudo phoenix sargentii Wendl., Myrica 

 cerifcra L., Polygala boykinii Nutt., Vitis rotundifolia Michx., Rhus blodgettii 

 Kearney, Pinguicula pumila Michx. and Baccharis angustifolia Michx. have 

 in all probability migrated from the United States to the Bahamas. As has 

 already been remarked, Myrica may have been introduced by man. 



If now we divide the Bahama Islands into two groups, the first or north- 

 eastern group, comprising Andros, New Providence, Abaco, Great Bahama, 

 the Berry Islands and their adjoining cays, and the second or southwestern 

 group comprising Eleuthera and all the islands south of it, it will be seen 

 from the above list that all except eight of the plants confined to the United 

 States and the Bahamas are found only on the northwestern group. This is 

 what we might expect from the proximity of this group to the Continent. 



There are at present, so far as I have been able to ascertain, fifty-six 

 endemic species reported from the Bahama Islands. These, with their dis- 

 tribution, are as follows:
