Plants in soil; rhizome short-creeping to erect, scaly
Leaves all alike or of 2 kinds, fertile and sterile; petiole in transverse section with vascular strands in a circle; blade deeply pinnately lobed to 1-pinnate with deeply pinnately lobed 1° leaflets, hairs generally 0; veins free or netted
Sporangia in linear to oblong sori along veins parallel to the nearest midrib; indusium shaped ± like sorus, opening towards nearest midrib; stalk cells in 23 rows; spores elliptic, scar linear
Genera in family: ± 9 genera, ± 250 species: worldwide, especially tropical. New growth often reddish; several species cultivated.
Rhizome suberect; scales brown
Leaves all ± alike or of 2 kinds, fertile > sterile, with much narrower 1° leaflets, deeply pinnately lobed to 1-pinnate with unlobed 1° leaflets; lower 1° leaflets reduced or not; veins of sterile leaves free

|YOU CAN HELP US make sure that our distributional information is correct and current. If you know that a plant occurs in a wild, reproducing state in a Jepson bioregion NOT highlighted on the map, please contact us with that information. Please realize that we cannot incorporate range extensions without access to a voucher specimen, which should (ultimately) be deposited in an herbarium. You can send the pressed, dried collection (with complete locality information indicated) to us (e-mail us for details) or refer us to an accessioned herbarium specimen. Non-occurrence of a plant in an indicated area is difficult to document, but we will especially value your input on those types of possible errors (see automatic conversion of distribution data to maps).|
