Scientific Name:Lonchitis
Description:Genus Description - Terrestrial; rhizome creeping, fleshy, stout, with pale hairs; fronds medium to large, monomorphic; stipe stout, fleshy, hairy, green, terete abaxially, ridged adaxially; blade ovate, bipinnate-pinnatifid, ridges continuous with those of costae; lamina membranaceous, herbaceous, with numerous septate hairs (in ours) or glabrous; veins free (in ours) to casually anastomosing; sori marginal on sides of segments, two per segment, lacking paraphyses; indusium submarginal from inner edge of marginal flange, broad, reflexed over sorus; spores tetrahedral-globose.

Discussion:Lectotype (first chosen by Brongniart in Bory de St. Vincent, Dict, class, hist. nat. 9: 490. 1826): Lonchitis hirsuta Linnaeus. See Lellinger (Taxon 26: 578-580. 1977) for discussion of typification. Anisosorus Trevisan ex Maxon, Pteridophyt. Porto Rico 429. 1926. Type: Pteris laciniata Willdenow [=Anisosorus hirsutus (Linnaeus) Underwood & Maxon in Maxon, = Lonchitis hirsuta Linnaeus]. Lonchitis has two species—one in Africa and one in America, the latter widespread in wet forests at middle elevations. It is sometimes placed in Anisosorus due to confusion with typification of Lonchitis and Blotiella (Lellinger, 1977). Lonchitis is distinct in its hairy rhizome, stipe and blade, and the membranous blade with free veins. References: Lellinger, D. B. 1977.
