College of Arts and Sciences

The University of Alabama Herbarium (UNA), the herbarium of the Department of Biological Sciences, houses about 64,000 specimens of vascular plants, about 6,000 specimens of mosses, and a few liverworts, lichens, algae, and fungi. These include The Mohr Herbarium (formerly ALU) ca. 4500 specimens on permanent loan from the Alabama Museum of Natural History.

The herbarium serves the three functions of the University: teaching, research, and service. Classes in botany make use of the collection for instructional purposes. A separate teaching collection is maintained with specimens of the local flora. The collections serve as a repository of research materials for study by students and faculty at the University of Alabama and, through loans, at herbaria worldwide. The collections are used for determining plants for the general public.

The herbarium is in the process of digitizing its specimen data. The data can be searched on the Global Biodiversity Information Facility (GBIF). We are participating in the Checklist of Vascular Plants of Alabama project and accompanying county level atlas and are reviewing the identifications in the collection to determine which species have been documented to occur in the state and in each county.

The herbarium is open for visits during normal working hours, which are 8:00 A.M. to 5:00 PM Monday through Friday except for holidays and subject to staff availability. To avoid any inconvenience, please contact the Curator, Dr. John Clark (jlc [at], or the Collections Manager, Mr. Steve Ginzbarg (sginzbar [at] prior to your visit.
