Selected Canadian Herbaria

Botany Collections: the National Herbarium of Canada

The Canadian National Herbarium is divided into four separate herbaria, each with its own international code: vascular plants (CAN); algae (CANA); Lichens (CANL) and Bryophytes (CANM). Today Nature's four herbaria together contain over one million plant specimens.

University of British Columbia Herbarium
The University of British Columbia Herbarium is the largest in Canada west of Ottawa, and is home to over half a million plant specimens from around the world. This collection is critical to the identification, monitoring, and conservation of plant biodiversity in British Columbia.

W.P. Fraser Herbarium (University of Saskatchewan)

The herbarium is part of the Plant Sciences Department, at the University of Saskatchewan. W.P.Fraser Herbarium (SASK) hosts a wide variety of plants representative from all over Canada and has over 170,000 specimens.

Selected International Herbaria

Flora of China
The Herbaria serve as an editorial center for the Flora of China, a collaborative project to publish the first, modern English-language account of China's vascular plants.

University of Florida Herbarium Library
The University of Florida Herbarium maintains a non-circulating reference library of publications pertinent to the naming and classification of vascular plants (plant taxonomy and nomenclature). The literature in this collection contains descriptions, geographical ranges and keys for differentiating species of vascular plants, as well as information regarding Latin plant names (nomenclature), plant collectors and economic botany.

United States National Herbarium Collections - Department of Systemic Biology, Smithsonian Institute.
The United States National Herbarium (US) was founded in 1848, when the first collections were accessioned from the United States Exploring Expedition (50,000 specimens of 10,000 species). Current holdings total 4.5 million specimens, making this collection among the ten largest in the world representing about 8% of the plant collection resources of the United States.

The Virtual Herbarium of the New York Botanical Garden
The New York Botanical Garden Herbarium is in the process of cataloging its numerous specimen holdings. The geographical emphasis of acquisitions for the Herbarium has always been on the flora and mycota of the New World. For this reason, our emphasis has been on cataloging NYBG New World collections.

Harvard University Herbaria
The Harvard University Herbaria, with approximately 5 million specimens of plants and fungi, rank eighth in the world in number of specimens. Included in the Herbaria are what were once seven separate herbarium collections:

Michigan State University Herbarium
The Michigan State University Herbarium represents a worldwide collection of all groups of plants, as well as lichenized and non-lichenized fungi. Current holdings number over 500,000 specimens, with approximately 315,000 specimens of vascular plants, 110,000 lichenized fungi, 35,000 non-lichenized fungi, and 20,000 bryophyte specimens. Over 1,800 type specimens are represented.
Oregon State University Herbarium

The Oregon State University Herbarium houses approximately 370,000 vascular plant, bryophyte, algal, and fungal specimens. The collections are worldwide in scope, with a focus on the state of Oregon and the Pacific Northwest.

The University and Jepson Herbaria - University of California, Berkeley
The University Herbarium (UC) and Jepson Herbarium (JEPS) represent the largest collection of herbarium material west of the Missouri Botanical Garden and the largest at a public university in the United States. All plant groups are represented in UC, which has a worldwide scope and particular strengths in marine algae, bryophytes, pteridophytes and flowering plants.

Nothern Ontario Plant Database
The Northern Ontario Plant Database (NOPD) is a website that provides free public access to herbarium records housed in northern Ontario educational and government institutions.

ITIS, the Integrated Taxonomic Information System!
Here you will find authoritative taxonomic information on plants, animals, and microbes of North America and the world. These comprehensive databases index the biota of North America. Search by scientific or common name. It is maintained by a partnership of American, Canadian, and Mexican agencies organizations and taxonomists.

Plants National Database
The PLANTS Database is a single source of standardized information about plants. This database focuses on vascular plants, mosses, liverworts, hornworts, and lichens of the United States and its territories. The PLANTS Database includes names, checklists, automated tools, identification information, species abstracts, distributional data, crop information, plant symbols, plant growth data, plant materials information, plant links, references, and other plant information.

The International Plant Names Index
The International Plant Names Index (IPNI) is a database of the names and associated basic bibliographical details of all seed plants. Its goal is to eliminate the need for repeated reference to primary sources for basic bibliographic information about plant names. /p>

Atlas of Florida Vascular Plants
The Atlas of Florida Vascular Plants is a joint effort by the Institute of Systematic Botany, the University of South Florida and the Florida Centre for Community Design + Research to provide users with a comprehensive searchable database of vascular plants in the State of Florida.

Illinois Plant Information Network (ILPIN)
ILPIN was designed to provide many different types of information about ALL of the vascular plant taxa found in Illinois. At this site, you can search on a species (by scientific or common name), and retrieve all the information we have compiled on the species, as well as a map of its known distribution among the counties in Illinois.

The Flora of Texas Consortium
A web-based herbarium specimen data access system that allows the user to 'browse' Texas specimen records. The current version, incorporating over 130,000 records from 7 Texas herbaria, includes various selection/filter options and either text or mapped display

The CalFlora Database
CalFlora exists to provide information on California plant biodiversity for conservation, research, and education.

IOPI Database of Plant Databases (DPD)
The Database of Plant Databases (DPD for short) is a global list of plant databases, to tell you who is putting together what data and where. The DPD contains virtually no plant data as such, but serves to put you in contact with the projects that do.

From Ohio State University, this resource provides both a factsheet database and a search engine for college and university resources related to plant science and horticulture. The factsheet database indexes guides for answering plant-related questions from 46 different universities and government institutions across the United States and Canada.
