This symposium is devoted to an examination of the impact of the rediscovery of Mendel and the consequent relationship between the new science of genetics and botany. Papers in this session highlight the contributions of individuals like E.B. Babcock, G. Ledyard Stebbins and Barbara McClintock and explore the varied institutional settings for the new science in agricultural, horticultural, as well as academic environments. The session is organized in honor of the centennial year of the rediscovery of Mendel by three individuals Hugo de Vries, Carl Correns, and Eric Von Tschermak and in honor of fiftieth anniversary of the book that integrated genetics with a range of botanical sciences by G. Ledyard Stebbins titled Variation and Evolution in Plants.

Key words: botany, G. Ledyard Stebbins, genetics, Mendel
