This species belongs to the group on which Schlechter bases his sections 

 Platychilus and Genychilus. It is well-marked by its strongly curved column 

 and the form of the lip, with a bidentate callus at the base. 



The flowers are described as green with a brown or creamy-brown 

 labellum.

Nearly allied to G. subracemosa J. J. S., but differing by the much less 

 warty sheaths, smaller flowers, a differently shaped lip, with much shorter 

 blade, and edentate clinandrium. 



The flowers are white.
