ORCHIDACE.E 



The dentation of the labellum is irregular with the teeth reduced 

 to triangular protuberances near the base and apex. In dried spe- 

 cimens the sepals and petals are whitish, the labellum yellowish. 



Leyte, Jaro, C. A. Wenzel 0388, April 30, 1914. Epiphyte in forest. 

 Altitude 500 meters. Sepals and petals red, labellum yellow and red. 



44. HIPPEOPHYLLUM Schltr. 



A small genus related to Oberonia and Liparis. About four spe- 

 cies are known. 



1. Hippeophyllum Wenzelii Ames in Phil. Journ. Sci. 8 : 413. 

 This species is perhaps more closely related to H. celebicum 

 Schltr. than to any other known species. The form of the label- 

 lum suggests H. micranthum Schltr. H. celebicum is a more slen- 

 der plant with large narrow leaves. 

 Leyte. 



45. LIPARIS L.C. Rich. 



The species of this genus are found in the temperate and tropi- 

 cal regions of both hemispheres. Twenty-seven species have been 

 reported from the Philippines. In previous publications I have 

 adhered to the generic interpretations of Pfitzer in my treatment 

 of these species. At present I am convinced that this treatment 

 necessitates an extremely artificial disintegration of a group 

 which is for all purposes best kept intact.
