Discusión taxonómica
Ceradenia oidiophora is readily distinguished from all other Mexican species of the genus by its orange rhizome scales and numerous white, oblong glands on the abaxial laminae. It has characteristics of both subg. Filicipecten (well developed stipes, dorsiventral rhizomes) and subg. Ceradenia (abaxial lamina bearing numerous whitish glands).A
