# Huernia

The genus Huernia (family Apocynaceae, subfamily Asclepiadoideae) consists of perennial, stem succulents from Eastern and Southern Africa and Arabia, first described as a genus in 1810.
The flowers are five-lobed, usually somewhat more funnel- or bell-shaped than in the closely related genus Stapelia, and often striped vividly in contrasting colors or tones, some glossy, others matte and wrinkled depending on the species concerned. Frequently the flowers are colored a variation of red, yellow or brown. To pollinate, the flowers attract flies by emitting a scent similar to that of carrion. The genus is considered close to the genera Stapelia and Hoodia. Phylogenetic studies have shown the genus to be monophyletic, and most closely related to the genus Tavaresia, and to a widespread branch of stapeliads comprising the genera Orbea, Piaranthus and Stapelia.
The name of the plant is in honor of Justus van Heurne (1587–1653?) a Dutch missionary, botanist, and doctor, who is reputed to have been the first European to document and collect South African Cape plants. His surname has variations (van Horne, Heurnius, van Heurnius), however it was misspelled by the plant collector.
Various species of Huernia are considered famine food by the inhabitants of Konso special woreda in southern Ethiopia. The local inhabitants, who call the native species of this genus baqibaqa indiscriminately, eat it with prepared balls of sorghum (kurkufa); they note that baqibaqa tastes relatively good and has no unpleasant side-effects when boiled and consumed. As a result, local farmers encouraged it to grow on stone walls forming the terraces, where it does not compete with other crops.
