Luzon, Benguet Subprovince, E. D. Merrill 7685, May, 1911, 50 kilo-

 the sea. 



94. ROBIQUETIA Gaudich. 



This is a small genus with representatives in Amboina, New 



Guinea, Celebes, Borneo, Sumatra, Tenasserim, etc. 



1. Robiquetia compressa Schltr. in Fedde Rep.Beheifte 1 :983. 

 Saccolabium compressum Lindl. in Bot. Reg. (1840) Misc. p. 9; 

 Sert. Orch. t. 32. 



The Philippine material which I have referred to Lindley's 

 Saccolabium compressum agrees fairly well with that species in 

 the floral structure, although the vegetative parts are not so 

 robust as those shown in the plate published in Sertum Orchi- 

 daceum. In the Lindley Herbarium at the Royal Gardens, Kew, 

 there is a sketch of a flower which agrees very well with the 

 details of flowers from Philippine specimens which I have ex- 

 amined. 



Dr. Schlechter has referred Saccolabium compressum to Robi- 

 quetia, in conformity with the present tendency to dismember 

 the genus Saccolabium. The sac is free from callosities. 

 Luzon, Mindanao.
