Thanks again Ken. Oerstedella centradenia is indeed a synonym of
Orchid (Epidendrum centropetalum) and I've added it as such.
Both the Catalog of Life and the Plant List reference the
Kew World Checklist for Oerstedella.
If you have a reference(s) where Oerstedella species are commonly used we can update the DB with the synonyms. Thanks.
