Oak fern

Dryopteride disjointe is not a valid binomial but apparently a "common" for a no longer accepted name for Dryopteris disjuncta which is now placed in the genus Gymnocarpium and known as Gymnocarpium disjunctum. Also, Gymnocarpium disjunctum does not occur in New York. This fern is not Gymnocarpium disjunctum or Gymnocarpium dryopteris or any other species of Gymnocarpium.
