A synopsis of Dressler (2001) from "The Cutting Edge," Volume VIII, Number 4, October 2001:
"A well-known ornamental Sobralia (Orchidaceae) with golden-lipped flowers, ranging along the Atlantic slope from Nicaragua to central Panama, has long been called either S. leucoxantha Rchb. f. or S. powellii Schltr. The latter name has been established as applying to a rather different sp. of central Panama. Now, examination of the type of S. leucoxantha (one of the two entities alluded to in the title) reveals that this name has also been misapplied; correctly, Sobralia leucoxantha is the oldest name for a more humble sp., of Costa Rica and Panama, heretofore known as S. macra Schltr. The flashier, golden-lipped sp., momentarily nameless, is here formally christened as Sobralia chrysostoma Dressler (the second entity of the title). No specimens are cited other than the type."
