Eupodium
Encyclopedia
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, and one recent molecular phylogenetic study supported the recognition of Eupodium as a lineage distinct from Marattia. The genus currently has three recognized species.
The basal chromosome number for this genus is unknown. The type species is Eupodium kaulfussii.
Fern
A fern is any one of a group of about 12,000 species of plants belonging to the botanical group known as Pteridophyta. Unlike mosses, they have xylem and phloem . They have stems, leaves, and roots like other vascular plants...

Marattia
Marattia is a small genus of primitive, large, fleshy ferns. It is the type genus of the family Marattiaceae. Formerly considered to be a much larger genus, recent genetic analysis by Murdock demonstrated its serious paraphyly, splitting off the genera Ptisana and Eupodium....

Ptisana
Ptisana is a genus in the eusporangiate fern family Marattiaceae, comprising species historically treated in the genus Marattia. The establishment of this genus follows the 2008 work by Andrew G. Murdock, which supported recognition of this group on the basis of genetic analysis and morphology...

Frond
The term frond refers to a large, divided leaf. In both common usage and botanical nomenclature, the leaves of ferns are referred to as fronds and some botanists restrict the term to this group...
