"Study of type specimens, complemented with examination of extensive amount of material of P. lanceolata from different continents, convinced me that the lectotype of P. leiopetala is a rather ordinary specimen of P. lanceolata. This conclusion was also annotated on the sheet by Alexey Shipunov in 2013 (see Figure 7). The same taxonomic conclusion applies to all herbarium specimens from Porto Santo Island identified as P. leiopetala that I came across during my herbarium revisions. Based on herbarium work and literature review, I conclude that these two names should be considered heterotypic synonyms, and the morphological variation attributed by Pilger (1937) to P. leiopetala should be included in the morphological circumscription of P. lanceolata. As further support for my conclusions, Rahn in Löve (1976: 499) and Dalgaard (1985: 144) reported the chromosomes of P. leiopetala as 2n = 12, which matches that of P. lanceolata (Rahn 1957).

Regarding the poorly known P. malato-belizii, my studies evidenced that, contrary to Rahn (1996), this name is not a synonym of P. leiopetala. Instead, I concluded that the name P. malato-belizii refers to a good species, which can be distinguished from the other species in Plantago sect. Lancifolia by the combination of the following characters: leaves 10–15-nerved, bract and sepals pilose on the keel and around the base, and anterior sepals connate for more than two-thirds of their length (see the description and illustrations in Lawalrée [1959], and also the identification key below)."
