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. macrophyllaHedberg, has also been described. [1]

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 .

Scrophulariaceae The figwort family of flowering plants

The Scrophulariaceae are a family of flowering plants, commonly known as the figwort family. The plants are annual and perennial herbs, as well as one genus of shrubs. Flowers have bilateral (zygomorphic) or rarely radial (actinomorphic) symmetry. The Scrophulariaceae have a cosmopolitan distribution, with the majority found in temperate areas, including tropical mountains. The family name is based on the name of the included genus Scrophularia L.

<i>Lathraea</i> A genus of flowering plants in the broomrape family

Lathraea (toothwort) is a small genus of five to seven species of flowering plants, native to temperate Europe and Asia. They are parasitic plants on the roots of other plants, and are completely lacking chlorophyll. They are classified in the family Orobanchaceae.

Orobanchaceae The broomrape family of flowering plants comprising parasitic members

Orobanchaceae, the broomrapes, is a family of mostly parasitic plants of the order Lamiales, with about 90 genera and more than 2000 species. Many of these genera were formerly included in the family Scrophulariaceae sensu lato. With its new circumscription, Orobanchaceae forms a distinct, monophyletic family. From a phylogenetic perspective, it is defined as the largest crown clade containing Orobanche major and relatives, but neither Paulownia tomentosa nor Phryma leptostachya nor Mazus japonicus.
