Eupodium is a genus of ferns in the family Marattiaceae native to the Neotropics. Traditionally, many taxonomists have included Eupodium within the genus Marattia (along with Ptisana). However, molecular phylogenetic studies and morphological studies of extant and fossil taxa support the recognition of Eupodium as a lineage distinct from Marattia. Morphologically, Eupodium was thought to be distinct among the Marattiaceae in only having one frond at a time (occasionally two), bearing awns along veins, and having stalked synangia (clusters of sporangia that have become fused in development). However, recent phylogenetic work found that an additional species native to Brazil, , which lacks these characters, is also genetically in Eupodium, making the genus harder to distinguish morphological
