3. Appearance

Gymnomitriaceae ferns have simple or compound fronds that grow alternately along the rhizomes. The fronds are typically green, shiny, and have a smooth texture. Gymnomitrion species have pinnate fronds with narrow, lanceolate leaflets that can grow up to 20 cm long. Pneumatopteris species, on the other hand, have bipinnate to tripinnate fronds that can grow up to 50 cm long. The rhizomes of Gymnomitriaceae ferns are creeping and can grow up to 10 cm long.
