Tectaria is a large pantropical genus (ca. 200 species), mostly developed in Southeast Asia and adjacent Pacific islands; there are 25-30 species in America, mostly of South America, with ca. eight in Mexico, two are very widespread. They generally occur on limestone at low elevations. See Dictyoxiphium for discussion of hybridization with Tectaria to produce the abortive-spored hybrid genus x Pleuroderris. Tectaria is distinct in its finely netted veins and round abaxial sori.
