This somewhat торыш Р. Віті Lindl, but has a shorter and less лвы 
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. Only two specimens of it have been collected as yet.
