Schizaeales 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: Download high resolution version (800x1067, 276 KB)The Climbing Fern, Lygodium japonicum, photographed in Hawaii where it is sparingly naturalized. ...

The family Schizaeaceae are generally small ferns with forking fronds and a distinctive, somewhat non-fern-like, appearance.
The family Anemiaceae look very fern-like but bear their spores 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 trailing vines.
