Salpichlaena

Terrestrial climbers with creeping, scaly rhizomes. Leaves are monomorphic to dimorphic and glabrous. The blade is 2-pinnate, with alternate, imparipinnate pinnae. Pinnules are entire or serrated at the apex and pedunculated. The rachis can grow up to 15 meters, is highly climbing, and voluble. Veins are simple or 1-forked near the base, connected by a submarginal branch. Sori are deciduous, leaving an apparently sterile pinnule. The indusium is tubular, dark brown, splitting irregularly, and breaking into fragments. It has a chromosome number of x=40.

Salpichlaena is characterized by its climbing rachis, entire pinnules, and sori elongated by the ribs. The only other genus in Mesoamerica with a climbing rachis is Lygodium, which differs by the arrangement of sori along the margins

The genus was described by botanist John Smith and published in the Journal of Botany, being a second series of the Botanical Miscellany 4: 168, in 1841. The type species is Salpichlaena volubilis (Kaulf.) Hook.^[1]
