Hedbergia

provided by wikipedia EN

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]

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.
