Olga Lakela Herbarium
You are here
The Olga Lakela Herbarium is located in rooms 62 and 76 of Marshall W. Alworth Hall (map) on the UMD campus.
It is a continually expanding collection of more than 48,000 dried botanical specimens housed in standard herbarium cabinets. Almost all of the specimens were collected from populations of native or naturalized vascular plants. In addition, there are small collections of algae, mosses, lichens, and fleshy fungi.
Approximately half of our specimens were collected by Dr. Lakela, and her extensive work in St. Louis and Lake counties of Minnesota is summarized in her book, A Flora of Northeastern Minnesota (1965, University of Minnesota Press). Olga Lakela founded this herbarium in 1935, and the University named it after her in 1960. A bequest from Dr. Lakela supports the maintenance and growth of the collection, as well as botanical research at UMD.
If you are interested in contributing to the Olga Lakela fund, find information on how to do so at the Swenson College website.
The collection is notable for its holdings of Canadian and northern U. S. plant species near the southern margin of their geographic range. The oldest specimen in the collection dates from 1846 (Florida), but most are from the 1940s through the present.
Plant scientists visit the herbarium for the purpose of examining specimens that are important in their research, or they may arrange for a loan of specimens to be sent to their home institution. Duplicates of specimens collected by UMD botanists are sometimes provided to other herbaria, usually in exchange for specimens we receive from them. The Olga Lakela Herbarium is listed in Index Herbariorum, with its international code being DUL.
Since 1990, Lakela Herbarium personnel provided the first documentation for the occurrence of many species outside of cultivation in their respective states. The list of these first occurring species can be found here. Additional information can be found at the University of Minnesota Herbarium and the Wisconsin State Herbarium.
A listing of the nomenclatural type specimens held by the Lakela Herbarium is provided.
Public Service and Teaching
Other services provided by the Lakela Herbarium include:
Identification of plants for the general public and for governmental agencies. Identification is done through comparison with the specimens in the collection, as well as a technical botanical library that is kept in the herbarium.
Specimens are also used for botanical instruction in the Biology Department. The Herbarium staff participate in the preparation of reports on areas where, in accordance with environmental protection laws, an examination for the presence of rare/endangered plants must be completed prior to any modification of the area.
In 1997, the Lakela Herbarium published "Rare Plants of Minnesota's Arrowhead", a pocket-size field guide to 56 non-grasslike species of northeastern Minnesota that were classified in 1996 by the Minnesota Department of Natural Resources as Endangered, Threatened, or of Special Concern. The authors of this book are herbarium associates Deborah Shubat and Gary Walton. The book includes a dot map and a color photocopy of a herbarium specimen for each species. This volume is now out of print.
