Dendrochilum Ramosii is a near ally of D. filiforme Lindl. from which 
it differs in the form of the labellum, and in the smaller flowers. In habit 
it resembles rather closely D. graciliscapum (Ames) Pfitzer. In dried speci- 
mens the flowers are brownish. The collector describes the flowers of living 
specimens as “orange, nearly yellow.”
