Abstract

My research is part of a larger project studying plants only found on gypsum (CaSO4·2H2O) soils in the Chihuahuan Desert of the southwestern U.S. and northern Mexico. Specifically, my project focuses on gypsum endemism within the subtribe Flaveriinae (Asteraceae, or sunflower family), which forms a small group of three genera: Flaveria, Haploësthes, and Sartwellia. My work has revealed much geographic structure to genetic diversity within Flaveriinae and a single origin of gypsum endemism in Sartwellia and Haploësthes.
