Eupodium

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, Eupodium is distinctive among the Marattiaceae in only having one frond at a time (occasionally two), bearing awns along veins, and having stalked synangia. Molecular phylogenetic studies and morphological studies of extant and fossil taxa support the recognition of Eupodium as a lineage distinct from Marattia.[1][2][3] The genus currently has three recognized species.[4]
