National Museum, also, Plants of the Bermudas, O. A. Reade, Ber- 

 muda, 1885). The flora of the more southern ones while still gene- 

 rally resembling that of Bermuda, also shows affinities with that of 

 the Greater Antilles. Probably the flora of Inagua will be found 

 to be much like that of Hayti and Eastern Cuba. Some Florida 

 plants are found in the Northern islands, but it is a question whether 

 they have come from Florida, or gone from the Bahamas. 



A grant was made by the British Association, in 1887, for the 

 in vest iiiatioii of the Bahama Flora, and Baron von Eggers of St. 

 Croix, known for his work in the Lesser Antilles, has accordingly 

 been in the Bahamas during the last year ; but I have seen nothing 

 of his results beyond a letter in " Nature " of April 12, 1888, p. 565. 



All such plants as have heretofore been listed and the additions 

 made to this list by Professors Dolley and Herrick, are followed by 

 the collector's name in brackets.
