“…longifolia ) cannot be separated in cluster results based on ISSR molecular markers [ 112 ]. The dendrogram presented by Soilhi et al [ 32 ] represents morphotypes that yield, among other findings, a deep split within ‘ M. spicata’ , while the molecular data results show very different, totally mixed-up groups (where M. longifolia , M. spicata , M. crispa and M. aquatica or M. × piperita are repeatedly included). Common reasons given for discongruity include the character or genetic marker selections, the complex hybridization histories and phenotypic plasticity [ 32 ].…”

“…However, most studies (but see [ 55 , 66 ]) have only investigated a limited number of species and/or individuals, largely ignoring inter- and intraspecific variation or discarding the taxonomical implications it has. Moreover, integrated genotype–phenotype analyses are not frequent, and often an insufficient number of genetic markers are used, or the morphological descriptors are scarce (but see [ 32 , 65 ]).…”

“…High intraspecific variability is clear from other molecular studies too (e.g., marker techniques AFLP, RAPD, ISSR and SCoT), which mostly led to very heterogeneous phylogenetic or phenetic results [ 32 , 61 , 98 , 104 ]. Choupani et al [ 111 ] repeat for Spicate and Capitate mints ( M. longifolia, M. spicata, M. aquatica etc.)…”

“…As rightly summarized by Soilhi et al [ 32 ], previous studies that combined molecular markers with morphological data found no agreement between the (clustered) results of both molecular and morphological markers separately [ 31 , 61 , 116 ]. Unfortunately, no such nrDNA or cpDNA sequence-based comparisons have been published in the case of Spicate mints.…”

“…Many authors (e.g., [25][26][27][28][29][30][31][32]) have already described the complex (morphological, chemical and molecular) diversity in mints. The complicated historical nomenclature (2630 names for Mentha on https://www.tropicos.org and https://www.catalogueoflife.org; accessed on 17 January 2021) strongly contrasts with the apparent simplicity presented by some authors nowadays.…”

The genus Mentha is taxonomically and phylogenetically challenging due to complex genomes, polyploidization and an extensive historical nomenclature, potentially hiding cryptic taxa. A straightforward interpretation of phylogenetic relationships within the section Mentha is further hindered by dominant but outdated concepts on historically identified hybrid taxa. Mentha spicata is traditionally considered to be of hybrid origin, but the evidence for this is weak. Here, we aim to understand the phylogenetic relationships within the section Mentha using large sample sizes and to revisit the hybrid status and identity of M. spicata. We show that two of three traditional species in the subsection Spicatae are polyphyletic, as is the subsection as a whole, while the real number of cryptic species was underestimated. Compared to previous studies we present a fundamentally different phylogeny, with a basal split between M. spicata s.s. and M. longifolia s.s. Cluster analyses of morphological and genotypic data demonstrate that there is a dissociation between morphologically and genotypically defined groups of samples. We did not find any evidence that M. spicata is of hybrid origin, and we conclude its taxonomic status should be revised. The combination of genetic and phenotypic information is essential when evaluating hyperdiverse taxonomic groups.
