(Lectotype, designated by Benedi 2003 , pg. 459: P [P-DESF]!; isolectotype G [00439692]!). Verbascum betonicifolium = Verbascum betonicifolium (Desf.) Kunze, Revis. Gen.

Notes. Benedi (2003) indicated as a lectotype the Desfontaines collection kept at Herb. P [P-DESF] but he omitted to mention another sheet of this collection kept at Herb. G (image available at https://plants.jstor.org/stable/viewer/10.5555/al.ap.specimen.g00439692). According to Lasegue (1845) and Stafleu and Cowan (1976-1988) , around 600 Flora Atlantica plants was given by Desfontaines to Lemonnier and was acquired by Delessert with the Lemonnier herbarium at Herb. G. In Herb. G we have traced one sheet, with barcode G00439692, that is stamped (Typus). This sample matches the collection locality in the protologue and it is the one that morphologically agrees best with the original description. This specimen bears two labels. The first has " Celsia betonicifolia Desf., Fl. Atl. [ Desfontaines' handwriting]"; the second is a printed label including, name, locality, reference, and a short historical French comment, and is annotated "R-L Desfontaines, Herbier de Barbarie / Celsia betonicifolia Desf. Loc: in arvis inculus Algeriae / Desf. Fl. Atl. II, P; 58, Tab. / Serie de 600 nos donnee par Desfontaines a L.-G. Lemnier; acquise en 1803 par B.
