Marattia
Marattia is a small genus of primitive, large, fleshy eusporangiate ferns. It is the type genus of the family Marattiaceae, order Marattiales and class Marattiopsida.[1] 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.[2][3] Except for one species in Hawaii, the genus is neotropical.

gollark: Odd.
gollark: You can't expect them to exactly match, but it worked out as about 1 in 4 in the average of loads of dragons.
gollark: Fun fact: according to my research the rate of tans is 1 in 4.

gollark: It is not.
