“…Our results strongly support Odontites to include Bornmuellerantha and Bartsiella, while the position of Macrosyringion remains doubtful in this respect (see below). The divergent corolla and anther morphology observed in Bornmuellerantha (Rothmaler, 1943;Bolliger, 1996;Dönmez & Mutlu, 2010) is a synapomorphy of its two species. However, both are deeply nested within Odontites s.l.…”

A molecular systematic approach using DNA sequences of two non‐coding chloroplast loci (trnK, rps16) and the nuclear ITS region was applied to reconstruct phylogenetic relationships within the tribe Rhinantheae (Orobanchaceae). This tribe includes approximately 19 genera of hemiparasitic plants predominantly occurring in the Old World. An exception is the genus Bartsia which, according to previous taxonomic treatments, includes a remarkable radiation (ca. 45 species) in the Andes, two species distributed in Afromontane regions, and only one species (Bartsia alpina) ranging from the alpine mountains of northern and central Europe to northeastern North America. The present phylogenetic study includes the most comprehensive taxon sampling of Rhinantheae to date, with main focus on the relationships of the Mediterranean genera. Both nuclear and plastid datasets reveal a core group of Rhinantheae comprising four major lineages. Our analyses suggest that (1) the northern temperate Bartsia alpina is sister to the rest of the core group; (2) African Bartsia are more closely related to the monotypic African genus Hedbergia than to other congeneric taxa; (3) South American Bartsia are nested within a highly supported clade including Parentucellia and Bellardia; (4) Nothobartsia and Odontitella are likely to be the results of at least one intergeneric hybridization event. Despite topological conflicts regarding some taxa, the polyphyly of Bartsia and a broadly circumscribed Odontites are unambiguously supported by our results. Our tree topologies indicate that the importance of certain morphological characters traditionally used for generic delimitation (such as shape and indumentum of corolla, anthers, and capsules) has been overestimated, and that some of these characters are presumably convergent. Available information on chromosome numbers corroborates the results presented here.

“…Table 2 summarizes the states of several morphological traits present in the species of the respective lineages. The morphological characterization of these five lineages is based on the comparison of the extensive descriptions found in the monograph by Bolliger (1996), Flora iberica (Rico, 2009), as well as in the papers where new taxa were described (Dönmez & Mutlu, 2010;Brullo & al., 2015). The morphologically most distinct lineages are clade K.2-Macrosyringion and clade K.3-Bornmuellerantha, which have at least five and three morphological synapomorphies, respectively; by contrast, the taxa belonging to clade K.4-Viscosus have only one (and a second character state is almost synapomorphic).…”

Despite the recent publication of several phylogenies focused on Rhinantheae, which has been expanded to include three Asian endemic genera, few studies so far have dealt with particular genera within the tribe. Here, we focus on Odontites and related genera because of the high morphological variability of the group and its unclear generic boundaries. Phylogenetic analyses were performed for nrDNA (ITS) and cpDNA (trnK region and rps16 intron) datasets, using Bayesian and Parsimony analyses. Our results cast doubt on the inclusion of Pterygiella and related genera within the Rhinantheae and support the paraphyly of Phtheirospermum, making it necessary to propose three new combinations to avoid it. Odontites is recircumscribed to include Bartsiella, Bornmuellerantha, and Macrosyringion, but not Odontitella. Within Odontites, five distinct lineages are identified. These are distinguishable either by morphological synapomorphies or by a combination of several character states. Most of the Odontites species are regarded as monophyletic. In the O. vernus and O. luteus complexes, some taxonomic changes are made to avoid paraphyly, which results in three new combinations.

The Odontites vernus group is the most widespread of the genus Odontites, occupying the temperate regions of Eurasia and northern Morocco. The group contains three species, all inhabiting the Iberian Peninsula, where O. vernus s.l. (sensu lato) exhibits remarkable morphological variability and includes diploid and tetraploid individuals corresponding to the two subspecies that occur there. We collected 301 individuals from 100 sampling sites covering the entire distribution of O. vernus in the Iberian Peninsula and genotyped them using 12 simple sequence repeat (SSR) markers. Their ploidy level was estimated by flow cytometry, and two cpDNA regions (rps16 intron and trnK‐rps16) were sequenced. We found 129 diploids and 172 tetraploids distributed following a mosaic parapatry model, while only two mixed‐ploidy populations were discovered. The 20 haplotypes found fit two well‐defined haplogroups, to some extent correlated with estimated ploidy levels. The frequencies of the SSR alleles shared by both cytotypes, as well as those of the private alleles corresponding to the tetraploid cytotype, indicate that tetraploids likely originated at least twice through autopolyploidy. Additionally, the results from SSR markers were structured in a higher number of groups than did the cpDNA sequences. Thus, the genetic distance analysis detected four groups, but the Bayesian analysis of population structure identified seven, with only low levels of gene flow detected among groups. The distributions of the seven genetic groups coincide with well‐known refugium areas within the Iberian Peninsula during the climatic oscillations of the Quaternary. Thus, the results give additional support to the “refugia within refugia” hypothesis.
