1 suppose tliis is the plant described by LiNDLtY under tlie name of 

 Liniatodis piinctata. The very short description is whoUy fitting it. 1 think 

 the différences with Ph. pauciflorus are tu slighl to keep it up as a 

 species. 



It differs from the type and from the variety described above by 

 the 2 conspicuous keels on the anterior part of the lip and the dotted 

 sheaths of the leaves. 



Description from some inflorescences preserved in alcohol.

 Bracts very light greenish yellow. Pedicel vvhite; ovary very light green.

 between the side lobes yellow; sidelobes with red veins; spur white with 

 a light purple dot on both margins at the base; anther yellowish."
