Farlow Herbarium (Harvard University)

The personal herbarium and library of William Gilson Farlow (1844-1919), eminent mycologist and phycologist and first Professor of Cryptogamic Botany in North America, bequeathed to Harvard in 1919, form the nucleus of the Farlow Herbarium and Reference Library. Further bequests from Roland Thaxter (1858-1932), as well as specimens, manuscripts, correspondence, illustrations and field notes from other notable researchers, including E. B. Bartram, E. A. Burt, W. H. Weston Jr., D. H. Linder, and I. M. Lamb, have further enhanced the collections. The Farlow Herbarium currently houses approximately 1,400,000 specimens, including approximately 75,000 types, of lichenized and non-lichenized fungi, bryophytes, diatoms and algae.

Herbarium Pacificum

The Bishop Museum, located in Honolulu, Hawaii, established in 1889, is the largest museum in the state and the premier natural and cultural history institution in the Pacific, recognized throughout the world for its collections, research projects, consulting services and public educational programs. The Herbarium Pacificum (BISH) includes approximately 79,000 macroalgal specimens, primarily from Hawaii and the Pacific. These specimens have been collected over the past 250 years by more than 1,500 phycologists, but most notably M.S. Doty and I.A. Abbott, and their students. While some of the oldest specimens were collected in the early-1800’s, approximately 35% are vouchers from studies undertaken within the past 50 years.

The George Safford Torrey Herbarium (CONN) supports botanical research in all disciplines including systematics, taxonomy, biodiversity, ecology, ethnobotany, palaeobotany, evolution and education. The herbarium combines significant palaeobotanical, bryological, lichenological, mycological, phycological and vascular plants totaling over 160,000 specimens, all housed in a fully modern, state-of-the-art facility. We are in the process of databasing our phycology collections. Over 2000 specimens have been entered to date. All specimens will eventually be imaged and made available on this site. Sample images are available for the genus Porphyra. The specimens were discovered in various parts of the Torrey Life Sciences Building during the move to the new combined collections facility. The majority of the collection dates from the latter part of the nineteenth century, starting around the mid 1870’s and is mostly from New England. Specimens range from those collected by eminent phycologists such as Frank Shipley Collins and Isaac Holden to other UConn collectors such as Andrew E. Wheeler, Joanna Page, George Safford Torrey and Frank Trainor. New collections are being added by students from the Biology of Algae course. A small minority of specimens are from Australia, Bahamas, California, Florida and Puerto Rico. Also included are exsiccatae separates from Algae Boreali-Americanae and the Phycotheca Boreali-Americana. Collins, Holden, and Setchell. With an active phycology faculty CONN is interested in exchanging duplicates to add to our collections. Comments on the data and requests to loan the specimens or receive archived high resolution images are welcome.

University of Hawaii at Manoa

Founded in 1908, the Joseph F. Rock Herbarium (HAW) serves the official university repository for plant specimens associated with student, staff, and faculty teaching and research. The herbarium was created by Dr. Joseph F. Rock's original collections and is the oldest herbarium in Hawaii. It is the result of decades of plant exploration by some of the leading researchers in the Pacific basin and today its use continues to expand. The herbarium is part of the University Museum Consortium, and comprises approximately 60,000 dried preserved plant specimens including algae, bryophytes, pteridophytes, angiosperms, fungi, and ancillary collections of 35 mm slides, wood, seed, and DNA. For more than 100 years, the herbarium has been a focal point for teaching, training, and education on the flora of Hawai'i and the Pacific with particular emphasis on vascular plants.

University of North Carolina Chapel Hill Herbarium

The University of North Carolina Chapel Hill Herbarium (NCU) is a Department of the North Carolina Botanical Garden of the University of North Carolina at Chapel Hill. The phycological collection is world-wide in scope and focuses on red marine algae of temperate zones. Important collectors include Max Hommersand, Fran Hommersand, and Paul Gabrielson. Ca. 30,000 specimens will be imaged & databased for the Macroalgal Digitization Project. Please note that algae specimens collected before 1995 by Max Hommersand were placed in formalin before being mounted on herbarium sheets. Paul Gabrielson's non-coralline specimens are a mix, and if pressed fresh this is noted on the specimen label. Gabrielson's coralline specimens were not put in formalin unless noted on the label. NCU also curates plant fossils (esp. Devonian), fungi (esp. collections of W.C. Coker & J.N. Couch), lichens, bryophytes, and vascular plants (esp. native flora of the Southeastern United States). NCU is open to the public & welcomes researchers.
