Wild and cultivated stimulant plant qat in areas of historic cultivation
Mark P. Simmons, Ph.D. Colorado State University, Fort Collins 

Qat (Catha edulis) is a woody plant native to eastern Africa that is cultivated for stimulant alkaloids. The wild origins and dispersal of cultivars have only been described in contradictory historical documents. Mark will present genetic evidence documenting the wild origins, human-mediated dispersal, and genetic divergence of cultivated qat compared to wild qat in Ethiopia, Kenya, and Yemen.

Dr. Mark Simmons is currently Professor and Curator of the herbarium at College of Natural Sciences, Colorado State University, Fort Collins.
