Abstract

Stem nearly erect to short-creeping, small, or long-creeping and rather slender, with a protostele, siphonostele or dictyostele, not indurated, bearing scales; leaves ca. 3 cm to 1 m long, simple, entire, or (in Hecistopteris) furcate, or (in Rheopteris) pinnate, circinate in the bud, petiole without stipules; sporangia borne in abaxial, often sunken, sori, or (in Anetium) the sporangia mostly in scattered groups on and between the veins and superficial, exindusiate; sporangia rather short-stalked, the stalk 1- to 2-rowed below its apex, the vertical annulus interrupted by the stalk; homosporous, spores lacking chlorophyll. Gametophyte epigeal, with chlorophyll, elongate and irregularly branched, sometimes with gemmae, archegonia borne scattered on the lower surface toward the margins, antheridia 3-celled, borne on the lower surface, mostly apart from the archegonia.
