NEW OR NOTEWORTHY ORCHIDS 
Panama plant for that species. In proposing P. alpina I do 
so with the realization that it differs from P. sicaria in 
minor details only, and may prove to be nothing more than a 
geographical variety. The labellum is obtuse, not acute as 
in P. sicaria, with the upper two-thirds spatulate rather than 
lanceolate. Lindley referred material from widely separated 
localities to P. sicaria, including P. tripteris Reichb. f. — 
a native of Venezuela—and on the same sheet with what I 
take to be the type of his species he mounted specimens of 
P. pantasmi Reichb. f. which had been obtained by Oersted 
in Nicaragua. His analytical drawings are from the Loddiges 
specimen originally sent from Trinidad. [Fig. 5.]
