Genus Haumaniastrum

For Lucien Leon Hauman (1880–1965), Belgian-born botanist who studied and collected plants in East Africa but whose main experience was with South America. He arrived in Argentina in 1804 and was a professor at the newly established faculty of agronomy and veterinary medicine of the University of Buenos Aires until 1925. He collected plants in Argentina, Paraguay, Uruguay and Chile and published many research papers. The Lucien Hauman Botanical Gardens of the University of Buenos Aires was named in his honour.
