Marattia is a small genus of basal, large, fleshy eusporangiate ferns, found in the Americas.
Formerly considered to be a much larger genus, genetic analysis has shown that Marattia in the broad sense was paraphyletic, and subsequently the genera Ptisana and Eupodium were split off.[1][2] Except for one species in Hawaii, 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.
Taxonomy
The Smith et al. classification of 2006, based on molecular phylogeny, placed Marattia in Marattiaceae. It is the type genus of the family Marattiaceae, order Marattiales and class Marattiopsida.[3] Subsequent classifications have maintained this placement.[4][5][6]
