Rhizomes short or elongate, creeping or less frequently climbing, covered with concolorous or discolorous scales, peltate, clathrate or not clathrate, or less frequently glabrous. Fronds articulate at the base, monomorphic, usually stipitate, glabrous, pubescent, or with scales; blades pinnatisect or simple-pinnate, the venation branched, free or reticulate, the areoles with a single free venule. Sori rounded or elliptical, usually terminal on the free venules; indusia absent; paraphyses present or absent. Spores bilateral, verrucose. rugose, or tubereulate, reniform, yellow.
