Rhizome-scale cells with lateral walls dark brown to ± black, surficial walls clear. Leaf: stipe ×-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.
1 or 2 genera (most segregates now subsumed in Asplenium), 700 species: worldwide, especially tropics. —Scientific Editor: Thomas J. Rosatti.

Plant in soil or on rocks; rhizome generally short-creeping to erect. Leaf: often tufted, generally glabrous; rachis often ± winged; blade simple or 1[many]-pinnate or forked; pinnae often more developed acroscopically, often without obvious midrib. Sporangia: indusia persistent, covering sori when young, later reflexed. (Greek: spleen)
