A near ally of Ph. corymbioides Schltr. und Ph. pauciflorus Bl., 

 especially of the former. The species differs from Ph. corymbioides Schltr. 

 in the fewer flowered inflorescences, the colour of the flowers, the lip not 

 being cuneate at the base but more or less rounded, papillons inside, 

 with 2 keels much swollen in c. '/a above the base and gradually evanes- 

 cent beyond the apex of the column, and the curved column. In the colouring 

 it resembles Ph, pauciflorus Bl. 



Ph. corymbioides Schltr. and Ph. labiatus J.J.S. both differ from 

 Ph. pauciflorus Bl. in the réduction of the side lobes of the lip, the conical 

 spur and the column being much dilated at the base and the apex.
