Pechuel-loeschea

Pechuel-loeschea, (common names; stinkbush, sweatbush, or bitterbos, ) is a monotypic genus of African plants in the elecampane tribe within the sunflower family, and named after the German plant collector and geographer Eduard Pechuël-Loesche (1840-1913).

The only known species is Pechuel-loeschea leubnitziae, (or 'wild sage' ) which is native to Angola, Botswana, Eswatini, Mozambique, Namibia, Zimbabwe and the Cape Provinces and the Northern Provinces, (in South Africa). The Latin specific epithet of leubnitziae refers to Leubnitzia, the maiden name of Pechuel-Loesche's wife.
