Welcome to ASTC: the Herbarium of Stephen F. Austin State University (Version 17.10.1)

The Stephen F. Austin State University herbarium (ASTC) with more than 79,000 specimens is the 4th largest collection in Texas. In addition to housing specimens from throughout North America, the collection represents nearly all of the vascular plant species found in the east Texas Pineywoods. The collection's curator is Dr. James Van Kley. The herbarium plays a vital role in teaching and provides crucial plant identification support to our research in vegetation science. Professionals engaged in research may visit the herbarium by appointment. We also entertain loan requests and facilitate specimen exchanges with other herbaria.

  • Imagery of our bryophyte collection and our small wetland and aquatic vascular plant collection is online. In the future we hope to add additional plant groups.
  • The holotype of Rudbeckia scabrifolia, a rare coneflower found only in certain herbaceous seeps in the east Texas Pineywoods is deposited in the collection.
