Dendrochilum ecallosum is very closely related to D. propin- 

 quum Ames, but differs from it in the much smaller dimensions 

 of all its parts. The ecallose labellum and marginate leaves serve 

 to distinguish it from D. bicaUosum Ames.

Dendrochilum (§ Acoridium) Loheri Ames Orchidaceae 3 

 (1908) 12, t. 27. 



This rare species which is represented by material recently col- 

 lected on Mount Santo Tomas by Boettcher was originally found 

 in Benguet Province, Luzon, by A. Loher and distributed without 

 being localized. On the evidence of herbarium material it would 

 seem to be confined to Mount Santo Tomas and IMount Pulog.
