Eduard August von Regel (also spelled Edward von Regel, Edward de Regel or Édouard von Regel; Russian: Эдуард Август Фон Регель; 13 August 1815 – 15 April 1892) was a German horticulturalist and botanist. He ended his career serving as the Director of the Russian Imperial Botanical Garden of St. Petersburg.[1] As a result of naturalists and explorers sending back biological collections, Regel was able to describe and name many previously unknown species from frontiers around the world.
