the sepals. Lip obcordate, deeply emarginate, about 1 cm. long ; 

 claw obscurely biauriculate, with two thin calli near the base. Col- 

 umn rather stout, about 2 mm. long. 



lonopsis utricularioides, Lindl., was described by Swartz toward 

 the end of the eighteenth century and referred by him to the 

 gentis Epidendrum. Early in the nineteenth century it was culti- 

 vated in European gardens under several names. In the American 

 tropics it is widely distributed, its most northern range being in 

 Florida, where it is exceedingly rare. On March 12, 1904, 1 found 

 ten or more plants near Naples on the Florida west coast ; there 

 the species grew mingled with other epiphytic orchids in a densely 

 wooded swamp several miles inland. The flowers bear some resem- 

 blance to those of Utricularia species, and to this fact the specific 

 name of our plant is due. The lip, which is the most conspicuous 

 part of the flower, has been variously described as obovate-obcor- 

 date with apex deeply emarginate, cuneate-bilobed, and obcordate- 

 emarginate. While these different descriptive terms may indicate 

 a variance in opinion as to the actual outline of this organ, they 

 also show the lip itself is variable. In Folia Orchidacea, Dr. John 

 Lindley described /. tenera as distinct from I. utricularioides, 

 but subsequent authors have considered the two conspecific. 

 Under /. tenera, Lindley assigned to our plant four varieties, and 

 to this number Cogniaux, in his work on the orchids for Martius's 

 Flora Brasiliensis, added two others.
