The name of this species was first published by Mas Guindal (1928 : 102), but without a description. A year later, Pau (1929) gave the description of Celsia masguindalii Pau based on the specimens collected by Mas Guindal in Rio Martin near Tetuan . In their 'Taxonomic and nomenclatural notes on some species of the genus Verbascum L. (incl. Celsia L.)', Benedi and Montserrat (1985) have wrongly cited the lectotype number (MA108989) for Verbascum masguindalii (Pau) Benedi & J.M.Monts. instead of the number MA108916 as shown by Nualart (2017) . Besides, Nualart et al. (2021) have traced two other eligible sheets (BC89918, BC141503) in Herb. BC. Those two specimens were also collected by Mas Guindal in Rio Martin , but without a collection date on the labels. According to Gonzalez-Bueno and Gomis (2007) and Nualart (2017) , Mas Guindal during his visit in Tetouan (Morocco) between 1926 and 1931, has collected many times at this site ( Rio Martin ).
