Teaching
I am in phased retirement, and no longer teach any courses.

Research Interests
I am a reader, traveler, and hiker fascinated by the natural history of western North America. I chose research opportunities that most interested me and would contribute substantially to teaching. I study the distribution of western North American plant species and plant communities. Within that, I focus on the comparative study of populations of widely distributed species complexes. (Species complexes are groups of populations where it is difficult to decide whether they comprise one species or several.) Deciphering these relationships entails field work, growing representative populations in a garden or greenhouse, experimental hybridizations among selected populations, and the study of chromosomes in the parental plants and in the artificial hybrids. Much of what I have been able to do stems from early support by National Science Foundation research grants. My newest interest is a handsome little sunflower. Pseudobahia heermannii lacks a "common name," but interests me because, unlike most other species, some plants have six chromosomes, others eight, and others ten. Experimental hybridizations may answer some of my questions.
