Type specimen 13114, A. D. E. Elmer, Puerto Princesa (Mt. 
Pulgar), Palawan, April, 1911. 
Here and there found standing upon red stony soil of densely 
wooded banks of the Iwahig river at 500 feet. 
All my material is without the bracts subtending the pedi- 
cels and the inflorescent branches. In R. wallichii Hook. the 
bracts are present and so are they in most of our other Philippine 
material.
