Brief History of the University of Arizona Herbarium

The University of Arizona Herbarium is as old as the university itself.

When U of A first opened its doors in students in October of 1891, the herbarium was located in Old Main and consisted of 700 native plant specimens from southern and central Arizona. Since that time, the collections have grown to over 350,000 plant specimens and over 100,000 mycological specimens.

Not only is ARIZ the largest herbarium in AZ, but it contains the largest collection of any herbarium in the world of plants from the Sonoran Desert region (Arizona, Sonora, and adjacent desert areas of California and Baja California). ARIZ also contains significant collections of plants from other regions of Mexico, and is home to numerous important historical collections, many dating back to the early 1800s.
