 in 2011, but Christenhusz and Chase, in 2014, reverted to combining the trichomanoid clades into "Trichomanes".The PPG I classification of 2016 again recognizes the segregate genera (and treats the two clades as subfamilies, Hymenophylloideae and Trichomanoideae), although the segregate genera are not always accepted by contemporary floras; e.g., as of 2016, the "Flora of New Zealand" preferred to recognize "Trichomanes" s.l.due to the difficulty of morphologically distinguishing the segregate genera.
