Rhizome creeping, stout, densely covered with hairs; hairs multicellular, sometimes consisting in several rows of cells, bristle-like. Stipes erect, smooth, glabrous. Fronds completely divided into two halves, each half divided into several unequal segments; main veins branched several times dichotomously, smaller veins anastomosing with free included veinlets in the areoles; texture coriaceous. Sori small, usually round, naked, scattered irregularly on the whole under surface of fronds, usually at junction of the smaller veins.
