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. bicallosum Ames.

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 Mount Pulog.
