This little plant has exactly the habit of Panisea parviflora 

 Lindl., but differs entirely in the form of the column which suggests 

 that of some species of Platyclinis or Pholidota. It is short and 

 sigmoid, with a tall oblong truncate hood to the clinandrium nearly 

 as long as the rest of the column and much overtopping the anther. 

 The rostellum is very prominent and thick, and the stigma cup- 

 shaped with a thick edge. The sepals have a strong thin wing or 

 keel running along the back.
