The concept Pterichis barbifrons, as illustrated by the 
type description of Prescottia barbifrons as well as by a 
photograph of the type specimen, appears to be reducible 
to the older Pterichis galeata. The only differences no- 
ticed are that the latter species is described as having 
glandular-tomentose floral bracts (as contrasted with the 
glabrous ones of Pterichis barbifrons) and that it has 
once-twisted petals, a character which is not observable 
in Pterichis barbifrons. 
Pterichis acuminata Schltr. is described as having one 
leaf, a character not mentioned in the allied species, but 
otherwise it apparently differs from Pterichis galeata only 
in having straight (not twisted) petals. 
The closely allied Pterichis Weberbaueriana Kriinzl. 
differs from P. galeata in having ovate-lanceolate petals 
(without a basal claw) and a lip with a solid apical lobe.
