The petals measure the same as the sepals. The labellum is shaped oblong and has an obtuse apex. The labellum measures up to 3mm long.

Additional Comments


Jim Comber named this species Dendrochilum rhodobulbon.


I have found this species one of the most challenging to find any information on. Jim Comber makes reference to Schlechter’s original description. Schlechter compared this species to Dendrochilum pallidiflavens but wrote that the small markings make it distinguishable.
