Lamourouxia is a genus of flowering plants in the family Orobanchaceae (the broomrape family), placed within the order Lamiales. The genus comprises approximately 14 species, according to GBIF. Orobanchaceae is a large and diverse family notable for containing many hemiparasitic and fully parasitic plants, and Lamourouxia belongs to this lineage of root-parasitic herbs distributed across the highlands of Mesoamerica and northern South America.
The genus was first described in 1818 by the botanists Friedrich Wilhelm Heinrich Alexander von Humboldt, Aimé Jacques Alexandre Bonpland, and Carl Sigismund Kunth, based on specimens collected during Humboldt and Bonpland's famous expedition to the Americas. The original description was published in Nova Genera et Species Plantarum (Vol. 2, p. 335), one of the landmark botanical works of the early nineteenth century.
Lamourouxia is distributed from Mexico south to Peru, with occurrences recorded in Belize, Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Honduras, Nicaragua, and Panama. The genus name commemorates Jean Vincent Félix Lamouroux (1779–1825), a French biologist and naturalist celebrated for his foundational contributions to the study of algae.
Etymology
The genus name Lamourouxia honours Jean Vincent Félix Lamouroux (1779–1825), a French biologist and naturalist who is particularly noted for his seminal contributions to the study of algae. The genus was named by Humboldt, Bonpland, and Kunth at the time of its first description in 1818.
Distribution
Lamourouxia is native to a range spanning Mexico south to Peru. It has been recorded in Belize, Colombia, Costa Rica, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, and Peru. A record for Magadan in Russia (cited by Kew) is considered a likely error.
History
The genus was described in 1818 by Alexander von Humboldt, Aimé Bonpland, and Carl Kunth and published in Nova Genera et Species Plantarum (Vol. 2, p. 335), a monumental seven-volume work documenting the botanical discoveries of the Humboldt–Bonpland expedition to the Americas (1799–1804). It is one of many Neotropical genera established in that work.
