opinion of Dr. Rudolf Schlechter as to its generic characters. 

 He agreed with me that the species was new and probably re- 

 ferable to the section Monochilus of Adenostylis. Later Dr. 

 Schlechter revised his opinion and we agreed that a new genus 

 should be recognized to receive the Philippine species. Further 

 studies indicated relationship to the genus Platylepis which has 

 representatives in Africa, Mascarene Islands, New Guinea, etc. 

 It would seem to indicate affinity to Platylepis through Pap- 

 uan and Pacific types of which the relationship to African spe- 

 cies of Platylepis is not yet wholly clear. 



Present records prove that Philippinaea is the only endemic 

 orchid genus of the Philippine Islands. If it should remain so, 

 it would be within reason to assume that the majority of the 

 orchid species of the Philippines have originated in the archi- 

 pelago and that their phylogeny may be traced to the species 

 of Celebes, Java, Borneo and Sumatra. (Plate 100.)

The labellum of this species was originally described as five- 

 carinate. I find that the number of carinae is variablCc In material 

 that I have referred to this species, three carinae seem to consti- 

 tute the average. A specimen in the United States National Her- 

 barium, Loher 54-9, that I regard as a duplicate type of C. Loheri, 

 has atricarinate labellum. In comparison with its Philippine allies,
