_ This plant I have no where met with. It evidently differs from P. triloba 
in its long bracts, undivided labellum, and short few flowered spike, and 
from P. setacea as is explained under that species. It is to be observed 
that the references made by Swartz. at p. 1399 to the figures of Neottias at 
t. 28 are evidently erroneous, and that fig c. not f. belongs to this plant.

acutà reflexà, cornu semilibero sepalis fere dupld longiore.

I have often .received this plant from garden collectors, but never with 
any intimation of its native country, which, however, is no doubt tropical 
America. The stem is from 3 to 4 feet high with a long loose spike of 
green flowers which are about as long as the intervals that separate them.

Ex Endlichero. 
In his Prodromus Endlicher says this genus is next to Spiranthes; but . 
in his Genera, although he places it in Neottez, he regards its affinity as 
doubtful. Does it not rather belong to Malaxidez ?
