Schizaeaceae (from the genus Schizaea, cleft, alluding to the leaves). Curly-grass Family. Fig. 3. Ferns of very diverse habit, some extremely small, others climbing: stem mostly oblique or horizontal: leaves very diverse, usually pinnate or palmate; veins forking: sporangia thin-walled, usually scattered, at first marginal, later sometimes exceeded by the margin of the frond, often appearing spiked or panicled, sessile; no apparent indusium; annulus transverse, apical, complete; dehiscence vertical; fertile portion of the frond usually much modified: prothallium of all genera except Schizaea ordinary; that of the latter genus filamentous and extremely branched, resembling that of the filmy ferns. In this family are 4 genera and about 70 species, mostly tropical, rare in the colder regions. Two species reach the eastern United States, one of which extends to Newfoundland. The solitary sporangia and transverse apical annulus are important characteristics. The curly grass (Schizaea pusilla) inhabits bogs, where it may form extended mats of dry, woolly "grass" 1-3 inches high. The sterile leaves are without laminae. Lygodium palmatum is the "climbing fern" of eastern America. The leaf, not the stem, of this plant has unlimited growth, and twines. Four genera are in the American trade: Anemia Lygodium, Mohria, and Schizaea. CH
