*LygodiaceaeSchizaeales is an order of fern (class
Pteridopsida ). The ferns in this order were once all lumped into the family Schizaeaceae in the old order Filicales. However, although they are demonstrably related, these ferns differ markedly, and so three groups have now been elevated to family status:* The family
Schizaeaceae are generally small ferns with forkingfrond s and a distinctive, somewhat non-fern-like, appearance.
* The family Anemiaceae look very fern-like but bear theirspore s on two completely modified lower pinnae.
* The family Lygodiaceae, or Climbing Ferns, look very ferny but are highly distinctive in their growth habit: the rachis of the frond is long and flexible, with indeterminate growth, so that the fronds form climbing or trailingvine s.
