From all other Philippine species Dendrochilum cymbiforme is clearly separ- 
able by means of its cymbiform, entire labellum and triangular, reduced, basally 
situated stelidia. In dried specimens the leaves are glossy above and leathery 
in texture. OC, cymbiforme appears ‘to be very distinct from all known species 
of the genus.

Dendrochilum Macgregorii is a slender species which resembles D. ewile in 
habit, although it is more closely related to D. Whitfordii than to any other 
known species of the genus. The labellum resembles that of D. Whitfordwi very 
closely. The narrow grass-like leaves which usually exceed the inflorescence, 
the shorter, denser racemes and the smaller flowers are characters which clearly 
distinguish D. Whitfordii. ‘The flowers in dried specimens are deep-madder.
