Neotypifications of Linnaean names in Hybanthus (Violaceae)

Abstract

Current studies in South American Violaceae detected the necessity of neotypes for Viola calceolaria L. (equivalent to Hybanthus calceolaria (L.) Oken) and Viola oppositifolia L. (equivalent to Hvbanthus oppositifolius (L.) Taub.), names of species originally described in Loefling`s her Hispanicum, but without validly published names.
