Professor of Botany, came to Arizona State University in 1964, after completing graduate studies at Ohio State University. He is director of the ASU Herbarium; Leader of the Arizona Recovery Team, Threatened and Endangered Species Program of U.S. Fish & Wildlife Service; a fellow of the Cactus and succulent Society of America; a member of the International Organization for the Study of Succulent Plants (IOS); and co-editor of the Journal of the Arizona-Nevada Academy of Sciences.

Our research program is twofold: biosystematic and revisionary studies of cacti and members of the sunflower family, and floristic studies of the Southwest and northern Mexico.

For the last several years we have been investigating interspecific hybridization in cacti, particularly in the genus Opuntia, utilizing chromosome, pollen and morphometric techniques. Polyploidy is common and its origin is via fertilization of unreduced gametes. Unexpectedly we learned that triploid plants are partially fertile and can produce reduced and unreduced gametes (at 1x, 2x, and 3x levels) capable of fertilizing reduced gametes of other diploid species. In the sunflower family, Hymenothrix also has triploid members capable of producing reduced and unreduced gametes, passing on genes to diploid parent taxa, contrary to old dogma. An interspecific tetraploid taxon is found to be out-competing one of its parental species for a significant part of its range. We are also conducting surveys of chromosome number and behavior for cacti, agaves, composites and others.

I have conducted floristic studies in the Cuatro Ciénegas Region of Coahuila, Mexico, an area rich in endemism, both plant and animal. I am also working on the Opuntia treatments for the new Chihuahua Desert Region Flora (completed), the Flora of North America, and the Flora of Mexico. I am also a co-editor of the upcoming Manual of the Vascular Plants of Arizona. Some of my students study the flora and vegetation of selected regions of Arizona, forming a database for future analyses of the impact humans have on desert species. We are also studying threatened and endangered species in Arizona to learn if management practices are effective in preventing extinction.
