Best known as a botanist and longtime University of Kansas herbarium director, this writer helped document the plants of the Great Plains in careful, field-tested detail. His books are especially valued by readers interested in flora, ecology, and the natural history of the American Midwest.

by Henry S. (Henry Sheldon) Fitch, Ronald L. McGregor
Ronald L. McGregor was an American botanist, plant collector, and scientific writer associated for decades with the University of Kansas. University of Kansas sources describe him as director of the herbarium from 1954 to 1988, a period in which the botanical collections grew substantially.
He is best known to many readers as the lead editor of Flora of the Great Plains, a major reference work on the region’s plant life, and as a coauthor of The Forest Habitat of the University of Kansas Natural History Reservation. His writing is practical and research-based, shaped by years of fieldwork and close study of native plants.
Available sources also note that he lived from 1932 to 2012. I couldn’t confirm a reliable portrait image from the pages I checked, so none is included here.
