It is a fern in the Ophioglossales. Its only species, M. chejuense,[1] grows only on Jeju Island of South Korea. While this plant is clearly ophioglossoid in the broad sense, its precise cladistic position is uncertain. It has a fused sporangial structure similar to Ophioglossum, but a vegetative structure, with palmately-radiating pinnae, reminiscent of Helminthostachys. It may be a basal offshoot of the ophioglossoid clade sensu stricto. ReferencesSun, B.-Y., M.H. Kim, C.H. Kim, and C.-W. Park. 2001.
