W. Elst at Haute Provence. Aline Raynal-Roques (b. 1937), professor of botany at the Muséum National d´Histoire Naturelle de Paris, is known for her investigations on taxonomy of tropical plants, mostly parasitic and aquatic, and research in the Sahel desert. Her work was honored in 1995 by the Institut de France.
