Hedbergia is a monotypic genus of flowering plants, initially classified in Scrophulariaceae, and now within the broomrape family Orobanchaceae. [2] It contains a unique species, Hedbergia abyssinica. [1] It is an afromontane genus, widespread in grasslands and scrubs of the mountains of tropical Africa, and known from Ethiopia, Zaire, Uganda, Kenya, Tanzania, Malawi, Nigeria, and Cameroons. [2]

Contents

The genus name is a taxonomic patronym honoring the Swedish botanist Karl Olov Hedberg.

Description

Hedbergia abyssinica is a 1–2.5 feet (30–76 cm) high, very hispid perennial plant, with subsessile thick leaves, and densely crowded, white to pink or magenta flowers. [3] [2]

Phylogeny

The phylogeny of the genera of Rhinantheae has been explored using molecular characters. [4] [5] Hedbergia belongs to the core Rhinantheae. Hedbergia is closely related to Odontites , Bellardia , and Tozzia . In turn, these genera share phylogenetic affinities with Euphrasia , and then with Bartsia .

<span class="mw-page-title-main">Scrophulariaceae</span> 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 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> 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.

<i>Odontites</i> Genus of flowering plants in the broomrape family

Odontites is a genus of flowering plants in the family Orobanchaceae.

<span class="mw-page-title-main">Paulowniaceae</span> Family of trees

Paulowniaceae are a family of flowering plants within the Lamiales. They are a monophyletic and monogeneric family of trees with currently 7 confirmed species. They were formerly placed within Scrophulariaceae sensu lato, or as a segregate of the Bignoniaceae.

<span class="mw-page-title-main">Orobanchaceae</span> Family of flowering plants known as broomrapes

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.

<i>Euphrasia</i> Genus of plants knowns as eyebrights

Euphrasia, or eyebright, is a genus of about 450 species of herbaceous flowering plants in the family Orobanchaceae, with a cosmopolitan distribution. They are hemiparasitic on grasses and other plants. The common name refers to the plant's use in treating eye infections.

<i>Melampyrum</i> Genus of flowering plants in the broomrape family Orobanchaceae

Melampyrum is a genus of about 20 species of herbaceous flowering plants in the family Orobanchaceae known commonly as cow wheat. They are native to temperate regions of the Northern Hemisphere. They are hemiparasites on other plants, obtaining water and nutrients from host plants, though they are able to survive on their own without parasitising other plants.

<i>Rehmannia</i> Genus of flowering plants in the broomrape family Orobanchaceae

Rehmannia is a genus of seven species of flowering plants in the order Lamiales and family Orobanchaceae, endemic to China. It has been placed as the only member of the monotypic tribe Rehmannieae, but molecular phylogenetic studies suggest that it forms a clade with Triaenophora. Contrary to the immense majority of the taxa of Orobanchaceae, Rehmannia is not parasitic.

<i>Rhinanthus</i> Genus of flowering plants in the broomrape family

Rhinanthus is a genus of annual hemiparasitic herbaceous plants in the family Orobanchaceae, formerly classified in the family Scrophulariaceae. Its species are commonly known as rattles. The genus consists of about 30 to 40 species found in Europe, northern Asia, and North America, with the greatest species diversity in Europe.
