Résumé
[EN] 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.
