ORCHIDACE^E 



there was only one tooth on the left side, while on the right side 

 there were two teeth. Although there may be differences between 

 the type and nos. 0132 and 0237 which constitute specific differ- 

 ences, I have been unable to detect them. The original descrip- 

 tion of Malaxis longipedunculata should be amplified to include 

 the forms characterized by three or four teeth on the labellum.

 I only know this from a sketch of the type, with analyses, kindly 

 given to me by Dr. A. B. Rendle. It is a larger flowered species 

 than M. quadriloba Ames from Luzon.
