shows quite plainly that the West Indies must lie 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 elata, 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 species, 

 Pelexia setacea, was collected l)y Mr. A. A. Eaton in Dade County. 

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

 the flowers ceased developing. Fn )m the liuds, however, analyses 

 were made that showed characters on wliich tlie 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 Lindl. 



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

 near Naples, Lee Count}', the flowers just opening. March 12(0. .1.). 



Epidendrum strobiliferum Rdili. f. 



On the lower limbs of Fersea carolinensit Nees., in " Palm Hammock," 

 near Marco. Only one station ; the plants in fruit. March 19 (0. .4.). 



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 mj' 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).
