The Tulane University Herbarium (Index Herbariorum
abbreviation NO) is one of the principal herbaria of the Gulf South region.
The University holds specimens of algae, bryophytes, and vascular plants, all
housed in Stanley Thomas Hall on the main campus in New Orleans. The
collections of algae are maintained primarily for teaching purposes. The bryological collections (ca. 2500 specimens) are mainly
of Gulf Coast mosses and liverworts representing valuable historical collections.
The vascular plant herbarium includes ca. 115,000 specimens of worldwide
representation, but is strongest in the flora of the southeastern United
States, southern California, the Rocky Mountain region of Colorado, and
northern Latin America, especially the Yucatan Peninsula of Mexico. Important
special collections include more than 300 type specimens, early plant
collections from the lower Mississippi River drainage, Arizona and California
ferns of J.G. Lemmon, and North American Gramineae
and Cyperaceae of Asa
Gray. Recent accessions include collections made by Tulane faculty and
students, and exchange material received from some thirty institutions
worldwide. Herbarium loans support a wide variety of monographic, floristic,
ecological, and ethnobotanical studies.
Research in systematic and taxonomic botany is further supported by the Minna F. Koch Library of Botany, a collection of more
than 1000 titles housed adjacent to the herbarium and rich in historical
botany and plant illustration, as well as worldwide floras, monographs,
dictionaries, and essential reference works.
The University's fungal collections (roughly 8,000 specimens) were donated
to The New York Botanical Garden in May of 1999.
High-quality images of all vascular plant specimens at NO may be found on
the CyberFlora Louisiana web site at http://www.cyberfloralouisiana.com/plantimages.html. As yet, the entire collection may be
searched by barcode (accession number) only.
Barcodes for all type specimens are available from this web site (Type Specimens, above); barcodes for other specimens can be
supplied upon request.
