Eusporangiate ferns are vascular spore plants whose sporangia arise from several epidermal cells and not from a single cell as in leptosporangiate ferns. Typically these ferns have reduced root systems and sporangia that produce large amounts or spores (up to 7000 spores per sporangium in Christensenia)There are four extant eusporangiate fern families distributed among three classes.
