Phylogeny

The phylogeny of the genera of Rhinantheae has been explored using molecular characters.^{[5][1][6][4][7]} 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.

The cladogram has been reconstructed from nuclear DNA (ribosomal ITS) and plastid DNA (rps16 intron, trnK, and other regions) molecular characters.[6][7][1][5][4]
