Notes.

In the protologue of Verbascum calycinum , Ball (1875) cited one gathering and he mentioned the collection locality reading "Legimus in regione inferiori Atlantis Majoris, convalle Ait Mesanet prope Sketana". However, he did not quote any herbarium that houses the original material or accession numbers specified, nor the date of collection. According to Stafleu and Cowan (1976-1988), the main collections of Ball are preserved at Herbs E and K, and also some at Herbs OXF and GL. During searches of Ball’s collections from Morocco, three specimens were traced. One of them is kept at Herb. P (P03420188) and another is stored at Herb. K (K000410937) and is mounted on the same sheet with K000410936. Both specimens K000410937 and P03420188 bear a label reading: "Iter Maroccanum. 1871 / Verbascum calycinum , Ball / Ex regione inferiori Atlantis Majoris, prope Sketana, alt. 1300-1400 met / Majo 18-19 / J. A. ball /". However, the specimen K000410936 bears a label reading "Ex rupibus arenaceis Atlantis Majoris in convalle Ait Mesan, alt. 1400-2000 met / Majo 13-16 / J. A. ball /". All of those sheets were collected by Ball in the High Atlas, Morocco. As the collection locality of both specimens K000410937 and P03420188 agree closely with the protologue, they can be safely considered as original material under Art. 9.4. of the ICN ( Turland et al. 2018). In accordance with Art. 9.3 of ICN ( Turland et al. 2018), the sheet K000410937 preserved at Herb. K is selected here as the lectotype, because it shows the best quality of preservation of the important diagnostic features.
