The University of Massachusetts Herbarium, Amherst, is a regional resource with approximately 241,300 mounted vascular plants, algae and bryophtyes as well as a fruit and seed collection. It includes three herbaria; the Amherst College Herbarium (AC), started in 1829 by Professor Edward Hitchcock and one of the oldest herbaria in the country, the Massachusetts State Herbarium (MASS) founded in 1867 by W. S. Clark, the third president of the University, and the recently acquired Phippen-LaCroix Herbarium (TUFT).

The collection is world wide in scope due in large part to an extensive exchange program during the time H. E. Ahles was curator (1966-1981), but the focus is on Western Massachusetts and New England. Other well represented geographical areas include Eastern North America and the tropical pacific (Collections largely from O. Degener and A. C. Smith).

Historically important collections include the "State Cabinet" (The Massachusetts state Herbarium collected prior to 1850), the 15,000 specimen collection of W. W. Denslow (1826-1868), and the 25,000 specimen collection of Addison Brown (1830-1913). The latter collection has specimens collected by Pringle, Parish, J. T. Howell and A. A. Heller and includes many types.

Collections of local interest include those of A. S. Goodale and colleagues from the Swift River Watershed, much of which is now under the Quabbin Reservoir, the New England collections of H. E. Ahles, and the collection from Deerfield and adjacent towns by Roberta G. Poland.

Recent large acquisitions (1996-2002) include voucher collections from Camp Edwards, Barnstable Co., MA (416 specimens), East Mountain, Hampden Co., MA (425), the flora of Worcester, Worcester Co., MA (700) as well as a collection of Massachusetts liverworts (200 specimens) and Bryophytes (85).
