In the Philippine Journal of Science (4 : 675 (C) Bot.) I re- 

 ferred material collected in Luzon by Ramos (Bur. Sci. 3055) 

 to Saccolabium chionanthum Lindl. Recently, in a review of sev- 

 eral genera of the Sarcanthinas, J. J. Smith assigned numerous 

 species, which had been retained in Saccolabium, to Lindley's 

 genus Sarcanthus. In Blume's genus Schcenorchis he placed sev- 

 eral species of Saccolabium that are partly characterized by linear 

 or terete leaves, among others Saccolabium chionanthum. The 

 synonymy proposed by Smith is given above. 



To Schcenorchis micrantha Bl. I refer the following Philip- 

 pine specimens which I have recently studied: 



Leyte, Dagami, C. A. Wenzel 05, November 8, 1912. On trees at great 

 height above ground, 60 meters above sea level. Flower odorless, white 

 and purple. Mindanao, Province of Agusan, Sangayan, Agay Trail, 

 C. M. Weber 319, December 11, 1911. On prostrate tree, 22 meters 

 above sea level. Also Palawan, Luzon.
