Discusión taxonómica
Oleandra lehmannii Maxon (which includes O. guatemalensis Maxon) occurs as far north as Guatemala, and should be looked for in Chiapas. It can be distinguished by its appressed, bicolorous rhizome scales and sori in one (rarely two) rows on either side and near the midrib. Oleandra bradei Christ of Costa Rica, which has creeping rhizomes with spreading scales and glabrous blades, has deciduous rhizome scales and pruinose rhizomes.A
