Plant Checklist for the Rocky Mountain National Park
I am an emeritus professor of Plant Biology from Southern Illinois University. But despite being retired, I am still active and engaged in many botanical projects. My main research specialization is parasitic flowering plants, however, I have a long-term interest in the taxonomy of all plants. This is evidenced by the botanical photographs I have taken in many parts of the world that are archived on the Phytoimages website. For more information about me, visit my professional web page HERE.
