A New Species of Goniopteris (Thelypteridaceae) from Hispaniola

Abstract

Abstract. Goniopteris baorucensis, a species known only from the Sierra Baoruco in the southern Dominican Republic, is illustrated and described as new to science. Recent phylogenetic studies have inferred it as a member of a clade of predominantly calciphilic Goniopteris that are largely endemic to the Antilles. New records of two additional uncommon species in this clade, G. hildae and G. nigricans, are noted. A short discussion of the history of pteridology in Hispaniola is provided, with special reference to the contributions of Erik Ekman and Carl Christensen.
