Discusión taxonómica
Elaphoglossum decursivum closely resembles E. lonchophyllum in its slender rhizomes, minute stellate hairs on stipes and blades, thin blades, and the vein tips laterally extended and sometimes uniting, but the former differs in the lack of resinous rhizome scales and the virtually sessile fronds.A
