Hedbergia longiflora, formerly Bartsia longiflora, is a species of flowering plants in the family Orobanchaceae.[2][1]
It is an afromontane species, restricted to the mountains of northeastern Africa.[3][4]
A subspecies, Hedbergia longiflora subsp. macrophylla Hedberg, has also been described.[1]
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.
