The TEX and LL herbaria contain over 1,000,000 total specimens and are among the largest herbaria in the southwestern United States. The facility ranks 13th in size across the nation. About a quarter of the specimens were collected in Texas, the largest holdings of Texas plants in the world. Nearly half of the specimens are from Latin America, with an especially strong representation from Mexico and northern Central America. Presently the number of new specimens accessioned into the Plant Resources Center’s herbaria is growing at an approximate rate of 7,000 per year.
The herbarium collection at UT contains many unique collections that are represented only here, or in very few other herbaria. Complete or nearly complete sets include the collections of Cyrus L. and Amelia Lundell, Marshall C. Johnston, James Henrickson, Robert Runyon, Elias Contreras, Percy H. Gentle, Eizi Matuda, and Billie L. Turner. The Plant Resources Center also has significant holdings of Donovan S. Correll, Sydney F. Blake, George B. Hinton and son, Harold N. Moldenke, Cornelius H. Muller, William A. Silvius, and Ivan M. Johnston, as well as significant holdings of Cyrus G. Pringle, Rogers McVaugh, and numerous other well-known plant collectors. Over 7,100 taxa are represented in the Type Collection.
The collection excels in holdings of the large plant family Asteraceae (sunflower family) from around the world, with more than 200,000 sheets. This large concentration of composites is partly due to the acquisition of the S. F. Blake collection of Asteraceae by the Lundell Herbarium. This large private collection was assembled by one of the foremost Asteraceae workers of the 20th century. Because of his willingness to identify Asteraceae from throughout the world, Blake amassed not only a large collection, but a very diverse one, both systematically and geographically.
The Blake collection is intercalated with the very large TEX collection of mostly North American Asteraceae assembled by the 60 or more monographers (most students and faculty at UT, especially B. L. Turner and his students, as well as J. Panero) who have worked in the U.S. Southwest and Mexico over the last 40 years. Comparatively few of these collections have been widely distributed among other U.S. institutions.
Because of the research interests of the staff and graduate students, especially comprehensive collections have been, or are being, accumulated for the plant families Chloranthaceae, Euphorbiaceae, Fabaceae, Fagaceae, Krameriaceae, Lamiaceae, Polygalaceae and Rhamnaceae. Also strongly represented are the Boraginaceae, Poaceae, and Scrophulariaceae.
In the late 1980s, the acquisition of the Lundell herbarium (LL) added ca. 315,000 specimens to the Plant Resources Center’s collections. These were accumulated throughout his career by the well-known botanist and archaeologist, Cyrus L. Lundell, who collected many specimens and also acquired the personal herbaria of several other botanists. With this acquisition, the Plant Resources Center became a major resource for material of the angiosperm families Celastraceae, Eriocaulaceae, Myrsinaceae, Sapotaceae and Verbenaceae..
The Plant Resources Center is located in the Main Building (aka. the Tower) on the campus of The University of Texas at Austin. Our main entrance is Room 127, located on the east hallway on the first floor (one up from ground). The collections are housed on eight floors within the building complex.
Access and Use
The herbarium is open for general use 8:30 A.M.-noon. and 1:00-5:00 P.M., Monday through Friday. Visitors wishing to use the collection for research or plant identifications are welcome; appointments are preferred but not required (see visitor policy). We encourage the use of our collections by both professional scientists and amateur plant enthusiasts and welcome faculty teachers, students, master naturalists and anyone else with an interest in collections-based botany or museum management. Visitors coming from off-campus by car should also request information on parking. Scientists wishing to consult the collections for extended periods may be furnished research space upon formal request to the Director or theCurator outlining their research objectives and funding sources. Scientists wishing to use material for studies that include sampling of specimens should consult our policy on the use of our collection for such studies.
