ORCHIBACEM 189 



Lower mountains of Luzon, on rocks and trees, June, 1905, A. 

 Loher (no. 6013). — Bosoboso, Prov. Rizal, Luzon, June 6, 1906, 

 Maximo Ramos (no. 969). 



The material on which the above determinations and description 

 are based agrees perfectly with the specimen in the herbarium of 

 the British Museum, collected by Cuming in the Philippines, num- 

 bered 2063. The specimens from Rizal Province are in a bad state 

 of preservation, the flowers having no lips, but apparently they 

 belong to this species. 



Endemic.
