Mankyua is a monotypic genus and 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.
The genus name of Mankyua is in honour of Man Kyu Pak (1906-1988), who was a South Korean researcher and botanist (Pteridology).[2]
The genus was circumscribed by Byung Yun Sun, Moon Hong Kim and Chul Hwan Kim in Taxon vol.50 (Issue 4) on page 1020 in 2001.
