116 Ame* Addition* to Orchid Flora of Florida. 



shows quite plainly that the West Indies must be reckoned with 

 to a large extent in the study of our semi-tropical orchid flora. 



The following list contains six species hitherto unrecorded as 

 natives of the United States. Two of them, however, on account 

 of inadequate material are here reported on provisional, though 

 reasonably sure, determinations. One, Liparis Plata, was re 

 ceived in 1903 from Lee County, Florida, where it was collected 

 by the late James E. Layne. No data accompanied the speci 

 mens, which were in a fresh state, one of them pushing up a 

 flower shoot that failed to reach maturity. The other spe"cies, 

 Pdexia setacea, was collected by Mr. A. A. Eaton in Dade County. 

 When received, Mr. Eaton's plants were partly frozen so that 

 the flowers ceased developing. From the buds, however, analyses 

 were made that showed characters on which the following de 

 termination is based. Of the remaining species, three were 

 collected by me on the west coast of Florida and one by 

 Mr. Eaton near Miami, on the east coast. 



lonopsis utricularioides Li mil. 



On low trees near pools of water. Found only in " Gobbler's Head," 

 near Naples, Lee County, the flowers just opening. March 12 (0. A.}. 



Epidendrum strobiliferum Rchb. f. 



On the lower limbs of Persea carolinensis Nees., in " Palm Hammock," 

 near Marco. Only one station ; the plants in fruit. March 19 (0. A.}. 



Epidendrum anceps Jacq. 



Common on deciduous trees, almost everywhere, not infrequently form 

 ing the main epiphytic orchid flora round muddy " lakes " in cypress 

 swamps ; Lee County, March 15-21 (0. A.). 



Pelexia setacea Lindl. 



In humus, in the dense shade of hammocks, fourteen miles south of 

 Cutler, Dade County, Dec. 10, 1903 {A. A. Eaton}. My specimens agree per 

 fectly with P. setacea, except for the spur, but the immaturity of my mate 

 rial may well account for discrepancies in this respect, as the spur must 

 lengthen considerably as the flower develops. 



Liparis elata Rchb. f. 

 Lee County, July, 1903 (/. E. Layne).
