This work has the objective of advancing the taxonomic knowledge of this section by revising and presenting novelties for the synonymy of P. subulata, including the lectotypification of four names with recent usage (since 1985) within this group: P. sarda, P. subulata var. atlantis, P. subulata var. granatensis, and P. subulata var. insularis. | Turkish Journal of Botany Research Note Turk J Bot (2018) 42: 653-661 © TÜBİTAK doi: Advances to the taxonomic knowledge of Plantago subulata (Plantago sect. Maritima, Plantaginaceae) Gustavo HASSEMER* Natural History Museum of Denmark, University of Copenhagen, Copenhagen, Denmark Received: Accepted/Published Online: Final Version: Abstract: Plantago sect. Maritima is a group of Mediterranean narrow-leaved plantains whose taxonomy and nomenclature are particularly complex and still unresolved. This work has the objective of advancing the taxonomic knowledge of this section by revising and presenting novelties for the synonymy of P. subulata, including the lectotypification of four names with recent usage (since 1985) within this group: P. sarda, P. subulata var. atlantis, P. subulata var. granatensis, and P. subulata var. insularis. Furthermore, two synonymizations are newly proposed, and the situation of two Plantago species names published by Nyman in 1881 in his Conspectus Floræ Europææ is clarified. Key words: Mediterranean, Plantagineae, Plantago sarda, synonymization, typification 1. Introduction Plantago sect. Maritima . is included in the genus Plantago L., subgenus Coronopus (Lam. & DC.) Rahn (Rahn, 1996; Rønsted et al., 2002; Hassemer et al., 2017a, 2017b). This section comprises a group of Mediterranean narrowleaved plantains whose taxonomy and nomenclature are particularly complex, and, despite having been studied since the earliest European botanists, the classification and nomenclature of this group remains unresolved (Di Pietro and Iamonico, 2014; Hassemer et al., 2017a, 2017b; Iamonico et al., 2017). The number of species in this section accepted by botanists since 1970 varies from four to 12 (Hassemer et al., 2017b). Among recent taxonomic works that treated this section (entirely or partially) the most important are those of Moore et al. .
