Fronds distant, monomorphic; stipe long, scaly; lamina usually simple, entire, sometimes lobed or irregularly lobed, or hastate, herbaceous or papery, scaly; veins anastomosing, areoles regular or irregular, simple to complex, free included veinlets simple or forked. Sori in 1 or 2 rows on either side of midrib, or in 1 row between 2 lateral veins, oblong or orbicular to confluent, sometimes linear or slightly irregular; paraphyses peltate, clathrate or simple uniseriate hairs with glandular apical cells.
