Former Eulophia pulchra was demonstrated by Martos et al., Taxon 63 (2014) 9-23 to group with Oeceoclades rather than with Eulophia.



Oeceoclades pulchra is an extremely widespread species, which in spite of its name is far from showy. It differs from the other species of Eulophia in New Guinea by its distinct, exposed pseudobulbs. When not in flower it resembles a species of Plocoglottis.
