 only know this from the description. It is said to have been im-

6. Sarcanthus sagittatus (BI.) J. J. Smith Orch. Jav. 607. Clei- 

 sostoma sagittata Bl. Bijdr. 363, f. 27. 



Among the Philippine species of Sarcanthus, S. sagittatus is 

 characterized by the sagittate terminal lobe of the labellum, by 

 the fleshy hammer-head shaped callus which closes the opening 

 to the cylindrical obtuse sac, and by the nearly obsolete septum. 

 S. sagittatus is a native of Java. The lateral lobes of the lip of 

 the Philippine specimens are not so acute as the lateral lobes 

 in J. J. Smith's figure published in the volume of plates which 

 illustrate his Die Orchideen von Java.
