ORCHIDACEM 137 



Cestichis gracilis is the smallest species of the section so far 

 known from the Philippines. It is readily distinguishable by its 

 very narrow leaves and slender pseudobulbs.

Cestichis disticha (Thou.) Pfitzer was collected by E. D. Merrill 

 on Mt. Halcon, Mindoro, in November, 1906. In habit it resem- 

 bles very closely C. gracilis. C. disticha is well characterized by 

 spathulate petals and a quadrate apiculate labellum. My concep- 

 tion of C disticha is based on a specimen collected by Thwaites 

 in Ceylon (no. 2359), and on a specimen, of which I have a photo- 

 graph, in the Leiden herbarium, which is stated to be "ex herb. 

 Thouars." For further details as to the occurrence of C. disticha 

 in the Philippines my paper, Orchidaceae Halconenses, in the Phil- 

 ippine Journal of Science (Botany, 1907), should be consulted.
