Note: 

An easily recognised and common species with short fat pseudobulbs and slender, much-branched inflorescences carrying quite small flowers. The only other orchid in New Guinea that is vaguely similar in this respect is the unrelated Ridleyella paniculata, which differs in many ways, for example in the free lateral sepals. Specimens in New Guinea often, but not always, have much paler coloured flowers than those occurring in the western part of the distribution area.
