Rhizome usually creeping. Fronds tufted, or scattered along the 
rhizome, simply pinnate in the New Zealand species, 2-3-pinnate and 
often palmate or pedate in others; texture subcoriaceous or membranous ; 
veins always free but often obscure. Sori marginal, in an early stage 
distinct and oblong or linear-oblong, decurrent along the tips of the 
veins, but soon becoming confluent and forming a continuous broad or 
narrow marginal band. Indusium formed of the modified edge of the 
frond, continuous, often very narrow, at first involute over the sori, 
ultimately spreading, often hidden by the ripe sporangia. Sporangia 
_ stalked, with an incomplete vertical ring, bursting transversely. 
About 60 species are known, found in the temperate and tropical regions of both 
hemispheres. One of the two New Zealand species extends as far north as India, the 
other is said to occur in Australia.
