Which is a type of fern, Adiantum or Hylomecon?
Adiantum Adiantum , the walking fern or maidenhair fern, is a genus of about 250 species of ferns in the Vittarioideae subfamily of the family Pteridaceae, though some researchers place it in its own family, "Adiantaceae". The genus name comes from Greek, meaning "not wetting", referring to the fronds' ability to shed water without becoming wet.
Hymenophyllum cristatum Hymenophyllum cristatum is a species of fern in the Hymenophyllaceae family. It is endemic to Ecuador. Its natural habitats are subtropical or tropical moist montane forests and subtropical or tropical high-altitude grassland. It is threatened by habitat loss.
