Swiss botanist (1871-1957).
Philippe-Auguste de Palézieux (1871, in Mies – 25 November 1957, in Geneva) was a Swiss botanist. In 1891 he started classes in mechanical engineering at the Eidgenössische Polytechnikum Zürich, afterwards studying botany at the University of Munich as a pupil of Ludwig Radikofer. From 1900 to 1939 he was a privatgelehrter (private scholar) in Germany, and spent much of his time in Berlin-Dahlem. In 1939 he relocated to Geneva, where in 1943 he succeeded Constantin Andreas von Regel as curator of the "Herbarium Boissier". From 1946 to 1949 he was president of the Société Botanique de Genève.
