Philippinaea Wenzelii (Ames) Schitr. & Ames comb. nov. 
Adenostylis Wenzelii Ames Orchidaceae 5 (1915) 41. 
The genus Philippinaea differs from Adenostylis in the details 
of the gynostemium and labellum. From the African members 
of Platylepis it is separable generically by the lip characters, 
although in the elongated column and in the rostellar divisions 
it shows close relationship with Platylepis through P. good- 
yeroides A. Rich. 
Philippinaea is endemic in the Philippines. It is monotypic and 
from evidence based on collections is only known from Leyte, 
Mindanao and Luzon. The material on which thegenus is founded 
was originallyreferred to Adenostylis and published in Fascicle V 
of Orchidaceae as 4. Wenzelii. Before publication I invited the
