Goniopteris moranii (syn.: Thelypteris guadalupensis; Thelypteridaceae), New to Florida and the Continental United States

The Goniopteris moranii is described. Goniopteris moranii is a widespread species occurring throughout the Greater and Lesser Antilles as well as southeastern Mexico. Goniopteris moranii is the fourth member of Goniopteris to be documented from Florida, and the third from South Florida. The other species include: G. tetragona (Sw.) C. Presl, known from five counties in Central Florida, G. reptans (J.F.Gmel.) C. Presl, recorded from nine counties in both South and Central Florida, and the state-endangered, G. sclerophylla (Poepp. ex Spreng.) Wherry, known only from Miami-Dade County in South Florida. Goniopteris moranii is distinguished from these species by each mature frond being mostly simplepinnatifid with only 1-4 pairs of free pinnae near the base.
