Caption

Twenty papers in the special issue of the <i>American Journal of Botany</i> explore the evolutionary importance of polyploidy. Research presented in this issue highlights recent advances in old and new topics in the study of polyploidy. This image shows <i>Crepis modocensis</i> subsp. <i>modocensis</i>, Lake County, Oregon, United States. Crepis was among the first plant genera studied using biosystematic approaches, and the landmark monograph by Babcock and Stebbins (1938) established the genus as a model for research on asexual polyploids. Sears and Whitton (2016) revisit Crepis with contemporary data and largely find support for the classic results of Babcock and Stebbins (1938).
