63. ERIA Lindl. 



In 1909 Dr. Robert G. Leavitt prepared a descriptive list of 

 the species of Eria native to the Philippines (Phil. Journ. Sci. 4 : 

 201-244 (C) Bot). To this list he admitted forty species, all but 

 six of which were thought to be endemic. Probably three hundred 

 species constitute the genus. In the monograph prepared for 

 Engler's Das Pflanzenreich, Kranzlin recognized § Trichotosia as 

 a genus. This treatment is hardly commendable. In the follow- 

 ing list Trichotosia is kept as a section.
