Real identity of Witheringia sellowiana (Solanaceae), typification and chromosome number

Abstract

The identity of Witheringia sellowiana, a narrow endemic species from São Paulo (Brazil), is reconsidered. After analysis of the protologue and the morphological characters of the type material and recent flowering collections, a new combination is proposed ( Aureliana sellowiana (Sendtn.) Barboza & Stehmann). A lectotype and epitype are designated here. A detailed description and illustration, an analysis of the karyotype of A. sellowiana, and a discussion of its closest relatives are provided. A key to differentiate the species of Aureliana is also given.Fil: Barboza, Gloria Estela. Consejo Nacional de Investigaciones Científicas y Técnicas. Centro Científico Tecnológico Córdoba.
