The R. L. McGregor Herbarium houses approximately 400,000 vascular plant specimens.

The collection is focused on the Central Grassland region of North America, with specimens from the Great Plains comprising approximately two-thirds of the collection. Families with especially strong taxonomic and geographic representation include Asteraceae, Cyperaceae, Fabaceae, Juncaceae, Lemnaceae, Plantaginaceae, and Poaceae.
