 glabrous, the npper or flower-bearing part pubescent and bracteolate. 

 Leaves 3 or 4, obliquely ovate, acute, tapering below to the channelled 

 sheathing petiole, 5-to 7-nerved ; length 2'5 to 4 in., breadth 1'25 to 175 

 in., petiole 1'25 in. Bracts of the upper part of the stem nearly 1 in. long, 

 lanceolate, acuminate, adpressed. Raceme abrupt, 2 in. or less in length ; 

 floral bracts finely acuminate, slightly longer than the ovaries. Flowers

This somewhat resembles P. Blumei, Lindl. but has a shorter and less 

 pubescent inflorescence, longer bracts and larger flowers. The leaves 

 have also twice as many nerves. The sepals and petals of this are of a 

 pale reddish-brown and the lip is white just as in P. Blumei.
