1903–1982
Best known for bringing the plants of the American South to life, this botanist spent decades studying Louisiana’s forests, wetlands, and wildflowers. His books paired careful science with a practical feel for the landscape, making them useful to both specialists and everyday nature readers.

by Clair A. (Clair Alan) Brown, Harold E. Grelen
Clair Alan Brown (1903–1982) was an American botanist and mycologist whose work became closely tied to the flora of Louisiana. Born in Port Allegany, Pennsylvania, he studied at the New York State College of Forestry and the University of Michigan, then built most of his career at Louisiana State University, where he taught from the 1920s until retiring in 1970.
His research ranged widely across botany, including plant identification, ecology, palynology, and forest studies, but he is especially remembered for documenting the plants of the Gulf South. Among the books associated with his name are Louisiana Trees & Shrubs, Palynological Techniques, and Wildflowers of Louisiana and Adjoining States. He also received major recognition during his career, including a Guggenheim Fellowship.
Brown’s writing has lasted because it was grounded in field knowledge as much as academic study. For readers interested in southern landscapes, native plants, or classic natural history, his work still reflects a lifetime spent closely observing the region.
