Dryopteris clintoniana
Introduction '''''Dryopteris clintoniana''''', commonly known as '''Clinton's wood fern''', is a fern of hybrid origin native to the northern hemisphere. It is a fertile hexaploid, arising as a species by doubling of its chromosome number from a hybrid between ''Dryopteris cristata'', a tetraploid, and ''Dryopteris goldieana'', a diploid. It is more northern in its range than either parent species.This fern will be found in wet areas, similar to the habitat of ''D. cristata''.
