Albion College

The Albion College Herbarium (ALBC) is a teaching collection of about 14,000 specimens, including 10,000 sheets of vascular plants and another 4,000 specimens of bryophytes, algae, lichens, and fungi. Most of its holdings are from the lower peninsula of Michigan. The herbarium of alumnus Charles W. Fallass, '1873 comprises the core of the vascular plant collection. Other contributors include former faculty members William J. Gilbert (1916-1994), Ewell A. Stowell (1922-2009), and 1956 alumnus Maynard C. Bowers (1930-). The Gilbert collections include algae from the S. Pacific. The Bowers collections include mosses from Finland and the western US.

E. C. Smith Herbarium

Today, the E. C. Smith Herbarium contains over 200,000 specimens, including vascular plants, bryophytes, and fungi. It is the largest herbarium in Atlantic Canada and the first Canadian herbarium to have a digital database with scanned images of the collection. The Acadia Herbarium began as an initial gift to Dr. H. G. Perry of a small collection made by G. U. Hay of St. John, New Brunswick. Included in this collection were a few plants collected by J. Fowler of New Brunswick before he went to Queen's University. These first specimens were collected between 1868 and 1880. Some of the plants were cultivated and some were from the United States. Subsequently, in these early years, the additions were made chiefly through the work of Dr. H. G. Perry and his students. No records were available until the collection numbered some 6,000 sheets. Included in the 6,000, however, are a number of sheets from the Gray Herbarium Expeditions to Nova Scotia in 1920 and 1921. Of the specimens above the 6000 count, the majority have been added by the work of Dr. M. V. Roscoe and her students from 1928-1940 and Dr. H. P. Banks and his students from 1940-1946. In 1946 a large collection was being assembled by Mr. David Erskine, who catalogued the Flora of Wolfville and vicinity. During Dr. E. C. Smith's tenure at Acadia (1947-1971) the number of specimens grew from 20,000 sheets to over 70,000. In 1970, Acadia University's Board of Governors announced that the department's excellent collection of plants would be named the E. C. Smith Herbarium as tribute to him for his contributions to the collection.

Field Museum of Natural History

Plants and fungi are essential to life on earth—key components of the planet’s ecology, biodiversity, climate, and human cultures. The study of plants and fungi is fundamental to medical science, conservation, genetics, agriculture, food-web studies, soil science, climate studies, anthropology, and many other fields. Field Museum botanists are leaders in the study of plant and fungi evolution, ecology, biogeography, environmental/climate impact, plant-animal interactions, and more.

Illinois Natural History Survey - Mollusks

The Illinois Natural History Survey Mollusk Collection contains over 190,000 catalogued specimens in nearly 50,000 lots, most of which were collected in Illinois and the southeastern United States. The collection is about 95% freshwater bivalves and gastropods (mussels, fingernail clams, and snails), 1% land snails and 4% marine gastropods, almost all of which are cones. Most of the specimens were collected as a result of various faunal surveys conducted by INHS biologists from the late 1800's until the present. The early collections were made by such naturalists as John Wesley Powell, Robert Kennicott, Richard E. Call, William A. Nason, Frank C. Baker, Robert E. Richardson, and Charles A. Hart. The largest and best documented collection of landsnails at the INHS was compiled by Thural D. Foster and organized by Frank C. Baker as part of his study on the "Landsnails of Illinois" published in 1939. The Baker snail collection numbers 1632 lots containing 11,970 specimens.

J. F. Bell Museum of Natural History - Fish

The fish collection at the Bell Museum of Natural History dates to the 19th century and contains over 41,000 cataloged lots. Early collections focused on fishes of the upper Midwest, especially fishes of Minnesota. However, there are many older collections from outside the state. These include specimens from the Menage expedition to the Phillipines in the 1890's; fish from Hawaii collected in the early 1900's; and many other specimens from across the continental United States. The fish collection also holds diverse holdings of marine fishes from the Pacific Northwest, Gulf of Mexico, and Atlantic coast. While most of the specimens are stored in alcohol there is: a large collection of pharyngeal teeth from cyprinids and catostomids; a sizable, uncataloged larval fish collection; and a growing collection of dry and stained-and-cleared skeletal material.

The vouchers for John Torrey's Flora of the State of New York (1843) formed the nucleus of the Herbarium. Because of the cultural and economic importance of the Albany-Troy area in the l9th century, the herbariumattracted collections of other early botanists, including Lewis Caleb Beck, Chester Dewey, H. P. Sartwell, Edward Tuckerman, the student Asa Gray, P. D. Kneiskern, and others. However, the bulk of the Herbarium is the result of the staff's collections and gifts and exchanges. Notable were the contributions of the first three state botanists, C. H. Peck, H. D. House, and E. C. Ogden, and the first designated curator, S. J. Smith.

Currently, the Bartley Herbarium consists of approximately 55,000 mounted and accessioned specimens, plus several thousand additional unmounted and unaccessioned specimens being processed. Of these, 30, 657 specimens were collected in Ohio, with the remainder being mostly from other parts of the eastern United States. Our Herbarium is the largest in Appalachian Ohio and seventh largest in the state. It is particularly rich in specimens from southern and southeastern Ohio, due to the efforts of Floyd Bartley and subsequent botanists who have been active in the region. It has the largest holding of vascular plant specimens from the unglaciated, Appalachian region of Ohio. The Bartley Herbarium is the main repository for flora projects conducted in this region, as well as the recipient of vouchers from ecological investigations and regional systematic studies of particular plant groups.

Seney National Wildlife Refuge

This herbarium represents an integral part of the history of the Seney National Wildlife Refuge. The first specimens in the collection date back to 1940. Since then, hundreds of plants have been collected, pressed, mounted, identified, and labeled by over 20 people with an interest in the vegetation of the Refuge. In 1964, Professor Edward G. Voss, a nationally recognized systematic botanist from the University of Michigan, examined the existing plant collection and made many corrections. New specimens (from 2010 onward) were verified by Dr. Anthony Reznicek (University of Michigan Herbarium).
