ADDITIONS TO THE ORCHID FLORA OF FLORIDA. 



BY OAKES AMES. 



The oivhid Horas of pL'niu.sular P^lurida and of the \\ est Indies 

 are so similar in the genera and species common to both that it 

 is not surprising to find, among recent additions to the list of 

 Florida oreliids, species known to be natives of Cuba, Porto Rico, 

 and Jamaica. During November and December, 11)08, six 

 genera new to Florida, including seven species, were discovered 

 by a single collector in Dade County. Most of these were found 

 in abundance and, as careful comparisons showed, were iden- 

 tical witli genera and species known to come from Cul)a and 

 .Jamaica. One species proved new to science, but in February, 

 U)04, was discovered by myself in the Province of Pinar del Rio, 

 near the town of Artemisa, forty miles west of Havana. In 

 March, 11)01, while on the west coast of Florida about eighty 

 miles from tlie end of the Peninsula, I found among otlier 

 orchids three species up to that time unrecorded from the 

 United States, one of them belonging to a genus new to Florida. 

 Of all of them I had ct)llected specimens previously in different 

 parts of Cul)a, one frequently in Pinar del Rio province. At 

 the present time, with the exception of Epidendnim b tin pease 

 Lindl. and E. ronopsenm R. Br., there is no epiphytic orchid 

 known to occur in Florida which has not also been reported 

 from Cuba and other parts of Tropical America, while the same 

 may l)e said of many of the terrestrial species; a fact which
