French botanist and mycologist whose early research dealt largely with plant anatomy and physiology; his doctoral thesis involving the adventitious roots of monocotyledons. With Gaston Bonnier (1853-1922), he performed extensive research of plant respiration, transpiration and carbon assimilation. In the early 1890s he is credited with the discovery of callose, a fundamental substance found in the cell membrane of plants. He died on 27 January 1937, aged 84, in Thiverval-Grignon.
