Founded in 1970 by Dr. Wesley E. Niles, the herbarium now holds about 70,000 specimens. Its primary focus is the vascular plant diversity in the Mojave Desert regions of Nevada, Utah, Arizona, and California. In 2023, the herbarium was transferred to the College of Southern Nevada.  It is housed in the building A of the Henderson campus. Important collections include those of T. Ackerman (Desert National Wildlife Refuge); J. C. Beatley (Nevada Test Site); V. Bostick (central and southern Nevada); D. Charlet (Nevada); I.W. Clokey (Spring Mountains); M.Kurzius, D. Schramm, P.
