Notes.

Verbascum atlanticum was described by Battandier and Trabut (1889) based on material collected south of Oran, Algeria. In the protologue, the authors did not designate a holotype, nor did they provide data about the herbaria housing the original material. According to Stafleu and Cowan (1976-1988), the plants collected by Battandier and Trabut are kept at Herb. MPU, but a number of duplicates can be found at Herbs P and RAR. We traced three specimens stored at Herb. MPU (MPU007787, MPU007788) and Herb. P (P00083087). The morphology of all three specimens agreed with the original description, and their locality was also in agreement with the locality data given in the protologue. It should also be noted that the specimens housed at Herb. MPU were mounted as two preparations for the same collection - sheets MPU007788 and MPU007787. Cross-labeling indicated that they were a single specimen (see Art. 8.3. of the ICN, Turland et al. 2018). The herbarium sheet P00083087 and those kept at Herb. MPU bore original labels handwritten by Battandier “Université d’Alger / Herbier de l’Afrique du Nord / Verbascum atlanticum Batt.! / Type! / Djebel Aïssa, rocailles grèseuses près de l’Aïn-Aïssa, 1600 m, / Leg J. A. Battandier". Referring to Art. 9.6 of the ICN ( Turland et al. 2018), all these specimens should be considered as syntypes. We selected sheet P00083087 as the lectotype, because it was in a better condition than the other Herb. MPU specimens, and part of its features closely agreed with the original description.

In his contributions for the Atlantic Flora, Battandier (1919) described another new species, V. pseudoblattaria , thirty years after the description of V. atlanticum . The original material of this new species, as referred to by Battandier (1919) in the protologue, was collected at Djebel-M’zi, south of Oran (Algeria). We traced two sheets at Herb. MPU (MPU006498, MPU006497), which are in complete agreement with the protologue and can be considered as original material. The sheet MPU006498 is selected here as the lectotype of the name V. pseudoblattaria , since it is in a better condition.
