33. TROPIDIA Lindl 



Among the collections made for the Bureau of Science at Manila 

 there are several specimens of this genus in fruit or incomplete 

 that may represent additions to the Philippine flora. Tropidia sep- 

 temnervisHe'ichb. f. (Ptychochilus septemnervis Schauer)is known 

 to me only from the plate in Meyen's Beitrage. Here T. minor 

 may belong. T. curculigoideslumdl. is cited by Naves. This species 

 is a native of Java, Borneo, and Malacca. It is not improbable 

 that Naves referred specimens, represented by one of the four 

 species in the following list, wrongly, to Lindley's species. 



1. Tropidia calcarata Ames in Phil. Journ. Sci. 7 : 7. 

 Luzon. 



2. Tropidia mindanaensis Ames in Elmer's Leaflets of Phil. 

 Bot. 5 : 1553. 



Mindanao. 



3. Tropidia mindorensis Ames in Phil. Journ. Sci. 2 : 315. 



MlNDORO. 



4. Tropidia minor Ames Orchidace^e 2 : 65. 

 Luzon. 



34. CORYMBORCHIS Thou. 



About twelve species are known. Corymborchis fiava is a native 

 of Mexico and the West Indies. Corymborchis is the generic 

 name adopted by Thouars. Corymbis is a uninomial formed from 

 the generic and specific names. According to the rules of nomen- 

 clature, Corymbis is not available.
