Genus Schizaea Family Schizaeaceae

Description: Rhizome creeping or almost erect, the young parts and stipe bases covered with coarse segmented hairs.

Fronds simple or dichotomously branched; stipe erect, slender; lamina reduced to a narrow wing or apparently absent.

Spore-bearing segments pinnately arranged at the apex of the frond or of its branches ('combs'); the sporangia attached along both sides of the segment, protected when young by the recurved margin of the segment; sporangia sessile, ovoid to ellipsoid.


Distribution and occurrence: World: c. 30 species, pantropical to southern temperate regions. Australia: 4 species, all States.

 Key to the species 
1Sterile fronds simple, flat, >1 mm wideSchizaea rupestris
Sterile fronds dichotomously branched, or simple and <1 mm wide2
2Sterile fronds simple, usually ± terete; the spore-bearing segments occupying the last 6–10 mm of the fertile frond when matureSchizaea fistulosa
Fronds almost always dichotomously branched, rarely simple but then the spore-bearing segments occupying the last 10–20 mm of the frond when mature
