Leytb, Dagami, C. A. Wenzel IS, December 10, 1912, on trees, 60 m 
above sea level, flowers 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.
