terrestrial plant with no flowers or bulbs sporangia present
Herbs reproducing by spores released directly from sporangia, the sporangia variously located [on abaxial leaf face, [LYCOPHYTES and FERNS]
Plant terrestrial or strongly emergent if in wet soil; leaf 3 pinnate, ; sporangia borne on aerial portion of leaf
Leaves all alike or nearly so, the fertile [sporangium-bearing] blades very similar in size and shape to sterile blades ; sporangia borne on underside of leaf blade, sori at ot near margin; new leaves generally coiled, unrolling as they develop
indusia 0 or sori covered by reflexed or recurved leaf margin or leaf margin segment
Pinnae [some or all of them] conspicuously toothed, lobed, or compound
Rhizome and base of petiole covered by hairs; rhizome long-creeping; leaf often > 80 cm, sometimes >= 2 m — blade widely triangular, 2–4-pinnate ..... DENNSTAEDTIACEAE
