Lectotypification of the Bertoloni's names in the genus Senecio L. (Asteraceae)

Abstract

Original material of the four Senecio taxa described by A. Bertoloni has been examined, and the typification of their names is discussed. A specimen from the Monti Herbarium (kept in BOLO) and iconographies from Bonanni and Bertoloni are designated as lectotypes, whereas another specimen from the Monti Herbarium is selected as neotype. The nomenclature of the names Senecio erucifolius L., Senecio tenuifolius Jacq., Senecio delphinifolius Vahl and Senecio rupestris Waldst. & Kit. is also analysed. The names S. crinitus Bertol. and S. laciniatus Bertol. belong to S. delphinifolius [now Jacobaea delphinifolia (Vahl) Pelser & Veldkamp] and S. rupestris [now Senecio squalidus subsp. rupestris (Waldst. & Kit.) Greuter], respectively, whereas S. erraticus Bertol. and S. praealtus Bertol. are accepted as separate taxa as Jacobaea erratica (Bertol.) Fourr. and Jacobaea erucifolia subsp. praealta (Bertol.) Greuter & B.Nord., respectively.
