Tins seems to be nearest to P. sciuroides RcHB. F., but the leavesare 

 broader, the flowers bilabiate with the mentum in a right angle to the 

 ovary, the lip longer and arcuate, A new ôesci\p[\(jn oi P. sciuroides RcHB. 

 F. from fresh materials is, liowever, indispensable for an exact comparison. 



The form of the expanded lip is very much the same as that of P. 

 longipcs J. J. S. 



According to a note of the collector the flowers are white and purple.
