  • Marattiopsida

Marattiidae is a subclass of class Polypodiopsida (ferns). This subclass comprises a single fern order, Marattiales, and family, Marattiaceae. It is equivalent to the class Marattiopsida in previous treatments, including Smith et al., 2006.[1]


Marattiidae is one of four subclasses of class Polypodiopsida (ferns), to which it is related as shown in this cladogram, being a sister group to Polypodiidae. The first three small subclasses are sometimes informally referred to as eusporangiate ferns, in contrast to the largest subclass, Polypodiidae or leptosporangiate ferns.[2]






In earlier classifications such as Smith et al. (2006)[1] it was known as Marattiopsida, but was renamed Marattiidae in that of Mark W. Chase and James L. Reveal[3] and subsequent systems such as Christenhusz et al. (2011)[4] and the Pteridophyte Phylogeny Group (2016). In that system, Marattiidae is monotypic has one order, one family, six genera, and an estimated 111 species.[2]
