Leyte, Dagami, C. A. Wenzel 13, December 10, 1912, on trees, 60 m 
above sea level, floivers white and purple. 
In habit Ceratostylis Wenzelii resembles C. radiata J. J. Smith rather 
closely but is clearly distinct from that species in the details of the flower. 
The sepals and lip in dried specimens appear to have been white, the petals 
purple.

The material which I have referred to this species agrees very well 
with the description of P. philippinensis. I have seen no authentic speci- 
mens of Brown’s plant.
