BRITTON: FLORA OF THE VIRGIN ISLANDS 25 



by Krebs and Knox are correct, there was a greater variety of plants 

 in gardens at the middle of the last century than at present. 



In citing synonyms for the names of plants, I have given the 

 original in cases where the species was first named in a genus other 

 than the one in which it is now included, and I also have indicated 

 the names used by previous authors dealing with plants of the islands, 

 in so far as I have been able to refer them, but no attempt has been 

 made to give complete synonymy. 



I gratefully acknowledge aid from Mr. A. S. Hitchcock in the 

 determination of some grasses and from Miss Margaret Slosson and 

 Mr. W. R. Maxon for information regarding some ferns.
