Past typifications of the 27 generic names allied to Salix (Salicaceae) published by Rafinesque in 1817 and 1838 are reconsidered in light of the current rules of nomenclature. A lectotype is proposed here for Diplima. Some generic names previously designated as lectotypes are here corrected to neotypes: Diplopia, Disynia, Oisodix, Opodix, Vetrix, and Vimen. Full bibliographic citations are given for each of Rafinesque's new names or combinations. Amerina balduiniana is lectotypified with a Baldwin specimen (ph) from Florida, and Vetrix linearifolia, a name that predates S. interior (1900), is lectotypified with a Nuttall collection (ph). However, a new combination in Salix is prohibited by the existence of S. linearifolia Rydb. (1901). To assure this, a step-two lectotypification is proposed for S. linearifolia. Oisodix fulva has been proposed for rejection. A John Bradbury collection, the type of Amerina missurica, has not been located, but if it proves to be a collection of S. amygdaloides Andersson as suggested recently by a monographer, the Rafinesque epithet would have priority. The use of Pleiarina (1838), a recently adopted segregate genus, as presently circumscribed is not correct, as Opodix (1817) has priority.
