Schizaeaceae is a family of
Anemiaceae, may be included in Schizaeaceae (as the subfamilies Lygodioideae and Anemioideae)[2] so that the family has four genera.[3][4] In this approach, the Schizaeaceae of PPG I is treated as the subfamily Schizaeoideae.[2]
Species are mainly distributed in the tropics, but several are found in temperate regions in North America, South Africa, Australasia and Northeast Asia.sporangia are borne on specialised pinnae, distinct from ordinary vegetative pinnae. The pinnae form small comb-like, pinnate structures on which the sporangia are formed.[citation needed]
Genera
In the narrow circumscription of the family, there are two genera:[1]
- Actinostachys Wall
- Schizaea Sm.
Two further genera are included in the broader circumscription:[3]
- Anemia Sm. – otherwise placed in the monotypic family Anemiaceae
- Lygodium Sw. – otherwise placed in the monotypic family Lygodiaceae
