Veins free, simple or forked or anastomosing without included veinlets, always ending near the margin. Indumentum composed of bracts and unicellular hairs occurring on the rhizome, the axes and the lamina surfaces. Sori short and discontinuous or long and continuous, usually borne on a secondary vein parallel to the costa, between the costa and the margin. Indusium linear, continuous or discontinuous, mostly entire, opening towards the costa, or exindusiate.
