Rhinantheae Explained

Rhinantheae is a tribe with fewer than 20 genera of herbaceous plants in the family Orobanchaceae.

Phylogeny

The phylogeny of the genera of Rhinantheae has been explored using DNA markers. 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 median crown age of Rhinantheae was estimated to be ca. 30 Myr.^[1]
