The University of Massachusetts Herbarium, Amherst

The University of Massachusetts Herbarium, Amherst (MASS) is a regional resource with approximately 258,000 mounted specimens from around the world, including 244,000 vascular plants, of which 97,000 are New England collections. Additional collections include 8,700 macroalgae specimens, 5,500 bryophtyes, a global fruit and seed collection, a New England seed collection, plant fossils, plant pathology specimens and a pollen collection.

The vascular plant collection is worldwide 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 Massachusetts State Herbarium, collected prior to 1850; the 15,000 specimen collection of W. W. Denslow (1826-1868); the W.D. Clark and D. P. Penhallow Collection, made in Sapporo, Japan in 1876-1877, when Clark was helping to establish the Sapporo Agricultural College (later Hokkaido University); and the 25,000 specimen collection of Addison Brown (1830-1913). The Brown collection has specimens collected by Pringle, Parish, J. T. Howell and A. A. Heller, and includes many type specimens.

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.

Incorporated herbaria include Amherst College Herbarium (AC), started in 1829 by Professor Edward Hitchcock and one of the oldest herbaria in the country,and the Phippen-LaCroix Herbarium (TUFT), acquired in 1998.

The macroalgae herbarium is a combined collection of specimens collected in the Pan-Arctic by Professor Emeritus of Phycology at the University of Massachusetts, Robert T. Wilce, and historic collections from Amherst College, in particular those of Timothy Field Allen, who was responsible for an early treatment of North American Characeae.

The University of Massachusetts herbarium with partner herbaria across the northeast have digitized the New England Vascular Plants and the macroalgae, both funded by grants from the National Science Foundation’s grant program Advancing Digitization of Biodiversity Collections.
