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.[1][2] Except for one species in Hawai'i, the genus is neotropical.
The plants are large and terrestrial, with more or less erect rhizomes and fronds being 2-5 times pinnate. Sporangia are fused into synangia, and spores are monolete.
Basal chromosome count is 2n=80. The type species is M. alata.
