Phylogeny

The phylogeny of the genera of Rhinantheae has been explored using DNA markers.[3][4] Three assemblages can be distinguished in this tribe:

  • Rhinanthus is the sister genus to Lathraea, and then to Rhynchocorys. These taxa are closely related to the core Rhinanteae.
  • In the core Rhinantheae, Odontites sensu lato, including Bornmuellerantha and Bartsiella, is the sister genus to Bellardia, including Parentucellia and Bartsia canescens + B. mutica. These taxa are closely related to Hedbergia (including Bartsia decurva + B. longiflora) and Tozzia. In turn, these genera share phylogenetic affinities with Euphrasia, and then with Bartsia sensu stricto (Bartsia alpina).
  • Melampyrum occupies an isolated, deep-branching position.

The cladogram has been reconstructed from nuclear and plastid DNA molecular characters (ITS, rps16 intron and trnK region).[4][3]


The median crown age of Rhinantheae was estimated to be ca. 30 Myr.[5]

Systematics

Rhinantheae is defined as the least inclusive crown clade that includes Pterygiella nigrescens, Rhinanthus cristagalli, Melampyrum pratense, and Tozzia alpina.[1] It comprises 19 genera.

gollark: So why are you *on* these bad servers?
gollark: Or, well, you can deduce that and you'll be wrong.
gollark: Unlikely.
gollark: Yes, I'm aware. You're wrong lots.
