Brief History of the University of Arizona Herbarium
The University of Arizona Herbarium is as old as the University of Arizona 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 420,000 plant specimens and over 40,000 mycological specimens.
Not only is ARIZ the largest herbarium in AZ, but it contains one of the largest collections of plants from the biologically diverse 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 to the 1800s.
