Welcome to Stephen F. Austin Herbarium (ASTC). Founded in 1949, the herbarium contains nearly 80,000 specimens and is the 4th largest collection in Texas. Personnel include Director Dr. James Van Kley, Curator Imani Harris, and long-time employee Macauley Parker. Although the collection includes specimens from throughout North America, its focus is on the East Texas Pineywoods, where it represents nearly all the native and naturalized species found in the region. The herbarium plays a vital role in teaching, as well as crucial plant identification support to our research in vegetation science. We also entertain loan requests and facilitate specimen exchanges with other herbaria.
