Rhizome creeping, white waxy or not, roots present. Rhizome scales pseudopeltate or peltate, clathrate or subclathrate, sometimes with hyaline margin, often with a central tuft of multiseptate hairs. Fronds monomorphic to dimorphic, simple or pinnatifid, membranaceous to chartaceous. Venation (all types): veins branching less than halfway or near margin, or seemingly close to the costa, connecting veins ana-or catadromous; included veins amply anastomosing; free veinlets excurrent and recurrent, recurrent in marginal areoles, sometimes with a distinct marginal vein. Sori always separate, round or elongate on veinlets, superficial or deeply sunken, scattered over the lamina or in one to several irregular rows between costa and margin. Paraphyses generally uniseriate, but sometimes biseriate or peltate and clathrate.
