Notes.

(1) When, Burdet et al. (1990) selected the lectotype of the name Verbascum haenseleri , they selected the sheet G00025472 as lectotype and sheet G00025473 as a syntype. An image of the lectotype is available at: https://www.ville-ge.ch/musinfo/bd/cjb/chg/result.php?type_search=advanced&lang=en&typecollection=&family=&genus=&species=&infraspecificname=&collector=&nocoll_operateur=%3D&debut_nocoll=&fin_nocoll=&date_operateur=%3D&debut_recolte=&fin_recolte=&country=&locality=&barcode=G00025472.

(2) Coincy (1895) in the protologue of Verbascum aurantiacum mentioned the collection locality as "Les pentes de la Sierra de Aquila près Baza (prov. de Grenade) le 8 juin 1895, à une hauteur que j’évalue à 1,200 m. environ [The slopes of the Sierra de Aquila near Baza, in the province of Granada, on June 8, 1895, at an altitude that I estimate roughly 1200 m]". However, no specific herbarium specimen was identified as a holotype, nor was where the original material was housed indicated. According to Stafleu and Cowan (1976-1988), the plants collected by Coincy are preserved at Herb. P, and further material can be found at Herbs B and LY. After conducting exhaustive research in the three different Herbrs (P, B and LY), we located one sheet at Herb. P (P03808542) that is a perfect match with the protologue. Hence, we designate this specimen (P03808542) as the lectotype for the name Verbascum aurantiacum .

(3) When he described Verbascum rotundifolium subsp. castellanum , Murbeck (1933) included in the protologue 14 gatherings that were collected in Spain by diverse botanists, but he did not indicate any herbarium specimen as a holotype. Only four specimens related to the gatherings mentioned in the protologue have been traced. Three of these specimens were found at Herb. MA (MA108791, MA108794, MA108789), and the other specimen was found at Herb. JE (MA108792). (JE00007506). The specimen MA108794 preserved Herb. MA is here designated as lectotype for the name V. rotundifolium subsp. castellanum because it is complete and matches the information in the protologue.
