The Filicophyta (alternately Pteridophyta) are the familiar group of
free-sporing
vascular plants commonly called "Ferns". These plants typically bear
their
sporangia in clusters (sori) on the undersides of their conspicuous
leaves.
The group exhibits a large degree of morphological variation ranging
from
large "tree ferns" to tiny floating aquatic forms.
