Notes.

Verbascum dentifolium was described by Delile (1836: 28; 1837: 287) based on material growing in the Montpellier botanical garden from collections made in Port-Juvenal at Montpellier. Port-Juvenal was a place where lots of wool bales were coming to France from the Middle East, introducing many species from seeds trapped in the wool. In his monograph of the genus Verbascum , Murbeck (1933) discussed in some detail the distribution and synonyms of a species to which this name has generally been applied, but he did not designate a lectotype for the name V. dentifolium . According to Murbeck (1933) the original material is kept at herbarium of Montpellier (MPU), in France. Research in Herb. MPU enabled us to locate two specimens bearing Delile’s handwritten labels and agreeing closely with the protologue’s description. The first one is mounted on two sheets. These two preparations, bearing the Herb. MPU barcodes MPU020144 and MPU020145, have a label reading " Verbascum, h. m. Julio 1826, N:10" that is accompanied by two other labels in which Delile gave a description of the species. According to Art. 8.3 of the ICN ( Turland et al. 2018), the sheets (MPU020144 and MPU020145) must be considered as a single specimen. The second specimen (MPU020146) bears a label reading " Verbascum dentifolium, h. m. Julio 1831". Since the type is not specified, the two specimens are to be considered as syntypes according to Art. 9.6 of the ICN ( Turland et al. 2018). The sheet corresponding to Herb. MPU barcodes MPU020144 and MPU020145 and with the collection date "Julio 1826" is selected here as the lectotype for the name Verbascum dentifolium .
