Rhizome-scale cells with adjacent walls dark brown to blackish, external clear
Leaf: petiole in transverse section with 1 X-shaped or 2 back-to-back C-shaped vascular strands; segment veins generally free
Sporangia in linear to oblong sori along veins; indusia linear, opening away from veins; stalk cells in 1 row; spores elliptic, winged
Genera in family: ± 10 genera (limits disputed), 650 species (most in Asplenium): worldwide, especially tropical.
Plants in soil or on rocks; rhizome generally short-creeping to erect
Leaves often tufted, generally glabrous; 1° axis often ± winged; blade simple or 1many-pinnate, rarely forked; 1° leaflets often asymmetric, upward side more developed
Sporangia in linear sori; indusia persistent, covering sori when young, later reflexed
Etymology: (Greek: spleen)

|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).|
