From all oilier Philippine species Dendrochilum oymUforme 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 
m texture. C. cymhiforme appears to be very distinct from all known species 
of the genus.

Dendrochilum Macgregorii is a slender species which resembles D. exile in 
labit, although It IS more closely related to O. Whitfordii tlian to any other 
known species of the genus. The labellum resembles that of D. Whitfordii very 
closely. The narrow grass-like leaves which usually exceed the inflorescence, 
the shorter, denser racemes and the smaller flowers are characters whicli clearly 
distinguish D. Whitfordii. The flowers in dried specimens are deep-madder.
