Through the courtesy of Dr. Peter Taylor, Curator of the 
Orchid Herbarium at Kew, I was able to examine the type-spe- 
cimen of Pogonia physurifolia. The dissection of one of the 
glued-down flowers revealed a triandrous condition of the col- 
umn. As a matter of fact, all details of the flower agree remark- 
ably with those collected by BROADWAY s.n.! in Grenada, the 
latter which was identified and illustrated by Ames as Psiloc hi- 
lus macrophyllus (Lindl.) Ames. — See Ames, Orchidaceae 7: 
45, Pl. 110, 1922. — The lip in P. macrophyllus differs in its 
different proportions and its short claw; P. Maderoi (Schltr.) 
Schltr. has a distinct keel on the long claw. The Ecuadorian 
material published as P. physurifolius is based on a wrong 
determination; its correct disposition will be given in the cur- 
rently published Orchids of Ecuador.
