Nearly 300 linear feet of materials
Collections in this category focus on the taxonomy, genetics, and physical structures of plants, and largely consist of historical research in the fields of botany, agronomy, pomology, and horticulture. Although materials relating to the scientific study of agricultural plants are not excluded, the collections in this category emphasize the biological and ecological aspects of plants, rather than their uses.
Several collections focus specifically on the anatomy and physiology of plant structures, including the papers of Ledyard G. Stebbins (world renowned geneticist), Esau, Proebsting, Weier, and Alden Crafts.
Information regarding plant varieties indigenous to specific geographic regions is the focus of three collections: the papers of Knowles Ryerson, Jack Major, and Harry Butterfield.
Materials comprise several formats; materials of a graphic nature, including drawings, original artwork, and posters are particularly abundant. There are no geographical or chronological limits to the collection, and the majority of the materials are in the English language. Related materials can be found under the headings of Agriculture, Agricultural Technology, Food Processing and Manufacture, Natural Resources, and Viticulture and Enology; see also the archives of the Botany and Pomology Departments in the University Archives.
