In the following paper orchids collected by Mr. Elmer in 

 Mindanao, Negros, Luzon, Palawan and Sibuyan are treated. 

 The greater part of the species described as new were found in 

 Mindanao and Negros. 



The genera are arranged according to the system adopted 

 in Engler and Prantl's "Die natiirlicheh Pfianzenfamilien." 

 Under each genus the species are placed in alphabetical sequence. 



Four genera, Diglyphosa, Dilochia, Lepidogyne and Tainia 

 are here recorded for the first time as natives of the Philippine 

 Islands. I^iparis latifolia Lindl. is new to the list of Philippine 

 species. Forty two new species are described. A complete set 

 of the specimens from which my descriptions were drawn is pre- 

 served in my herbarium. 



From Mr. Elmer's very full field notes I have quoted liberally, 

 incorporating in my descriptions information as to color of flowers 

 and leaves, and as to other peculiarities which are usually lost to 

 view in herbarium specimens.
