what assumption I do not know. In the Philippines Hahenaria 

 malintana appears to be common in Luzon. 



VANILLA Juss. 



Vanilla calopogon Reichb. f. Otia Bot. Hamb. Fasc. 1 

 (1878) 40. 



This appears to be a very rare species. Among the collections 

 examined I have seen only three sets of specimens. Vanilla calo- 

 pogon Reichb. f. is readily distinguished from V. ovalis Blanco, 

 the only other species of the genus heretofore reported from the 

 Philippine Islands, by its leafless stems and white flowers. Up to 

 the present time this species has been found only in Luzon. The 

 following collection is worthy of a record. 



Luzon, Ilicos Norte Province, Burgos, M. Ramos Bur. Sci. 32928, July 

 20, 1918. In dry thickets. Flowers white. 



LECANORCHIS Bl. 



Lecanorchis javanica Bl. Mus. Bot. Lugd.-Bat. 2 (1856) 

 188. L. triloba J. J. Sm. in Bull. Dept. Agric. Ind. N^erl. 19 

 (1908) 26. 



In Fascicle V of this work, I adopted for this species the name 

 proposed by J. J. Smith in Bull. Dept. Agric. Ind. Neerl. Smith 

 is now of the opinion that L. t?nloba should be added to the syn- 

 onymy oi L. javanica BL, on the assumption that Blume must 

 have described his species from a peloric form in which the label- 

 lum was entire instead of being normal and three-lobed. The 

 type of L. javanica at Leiden is in poor condition and insuffi- 

 cient to establish beyond doubt that Smith is correct. Smith 

 has examined material from western Java that is characterized 

 by a three-lobed lip, and his studies have convinced him that 

 L. tiiloba is not a distinct species, but simply the normal state of 

 L. javanica,
