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.
Ophioderma falcatum Ophioderma falcatum is known as puapua moa or laukahi in Hawaii. It is a fern in the Ophioglossaceae family, and many people still classify it as an "Ophioglossum". Some consider it a subspecies of "Ophioderma pendulum". An epiphyte, it is native to the Hawaiian islands except for Ni'ihau and Kaho'olawe. It also grows on some other Pacific islands.
