  ## Phylogeny
  
  The phylogeny of the genera of Rhinantheae has been explored using molecular characters. Hedbergia longiflora groups with Hedbergia decurva and Hedbergia abyssinica into a Hedbergia clade nested within the core Rhinantheae. These three taxa share evolutionary affinities with genera Tozzia, Bellardia, Neobartsia, Parentucellia, and Odontites.
