large, 4.5 cm. in diameter, in loose racemes. Sepals and petals

Mt. Balabac, Bulacan, Prov. Luzon, flowering in Manila, June 

 11, 1905, A. Loher (no. 6006). 



Although the material on which my determination is based has 

 been regarded by Mr. Loher as specifically distinct from all other 

 Vanda species, I am of the opinion that it represents a color variety 

 or form of V. tricolor. According to field notes the sepals and 

 petals are white, and the flowers nearly or quite odorless. Mr. 

 Loher says that the plants grow in high trees, where they form 

 heavy clumps.
