The rare book collections (especially History of Science Rare Book Collection) are particularly strong in the history of plants and botany. Linnaeus' monumental works, Systema Naturae, Species Plantarum, and Genera Plantarum are all present in original or early editions, representing the establishment of the standard hierarchical system of kingdoms, divisions, classes, orders, families, genera, and species, as well as the system of binomial nomenclature. The geography of plants is well represented in the collections, as are regional floras.
