The Missouri Botanical Garden’s Herbarium is one of the world’s outstanding research resources for specimens and information on bryophytes and vascular plants. The collection is limited to these two major groups of plants. As of 2018 the collection has nearly 7 million specimens.

The Herbarium at MO is divided between two buildings. The Bryophytes, Pteridophytes, Gymnosperms, Monocots and Dicots through the Fabaceae (family 128) are located in the Lehmann Building, at the south end of the Garden grounds, while Dicot families from Pandaceae (family 128A) through Asteraceae (family 280) are in the Bayer Center (4500 Shaw Blvd.).

Special Collections

DNA Banking

Liquid Preserved

As an aid for research in molecular phylogenetics the Herbarium maintains a collection of material specifically intended for DNA extraction. Botanists at the Missouri Botanical Garden collect leaf samples, preserve them in silica gel and store them at -20º C. Because the samples are carefully prepared and stored, they are likely to give better yields of higher quality DNA than herbarium material. To date, nearly 11,000 samples have been catalogued and are available for distribution. The catalog of this material is available online. Please contact the Curator of the Herbarium if you are interesting in obtaining samples for extraction.

A collection of about 4,000 accessions of liquid preserved plant parts is also available for consultation and study. These plant materials represent a diverse array of families, but are concentrated in groups that have been the special research interests of the Garden staff.

Other Facilities



The Library is located on the 4th floor of the Bayer Center (4500 Shaw Blvd.). The general collection consists of more than 200,000 volumes of monographs and journals. More than 800 current periodicals are received through subscription and on exchange. The main emphasis of the collection is on plant taxonomic literature, current and retrospective, collected in all languages. Other special collections include: over 3,000 reference works; 1,100 Sturtevant Pre-Linnaean volumes; 4,000 post-1753 rare books; over 1,000 folio volumes; the personal collections of Ewan (11,000 books), Steere (1,000 volumes), and Niederlander (600 volumes); 7,000 items of botanical art; map and atlas collection (over 7,000 items); and microfiche (45,000 fiche). To arrange a visit the library, please e-mail or call (314) 577-5155.

The Archives includes more than 3,000 linear feet of Garden records and publications, professional and personal papers, historic manuscripts, Garden photographs, oral histories, original artwork from Garden publications, and architectural drawings. Noteworthy are the personal papers of Henry Shaw, including letters, account books, diaries, and legal papers documenting his business transactions and the development of the Garden. The George Engelmann Papers, numbering some 5,000 letters and 30 boxes of botanical notes, are resources for the history of nineteenth-century botany and exploration of the West. Other important collections include the papers of Peter H. Raven, Alwyn Gentry and Julian Steyermark. An appointment to consult the Archives can be made by contacting Andrew Colligan at (314) 577-5158.



The publishing arm of the Science and Conservation Division is MBG Press. The Press produces Annals of the Missouri Botanical Garden, Novon, Monographs in Systematic Botany from the Missouri Botanical Garden, as well as numerous floras and other botanically related publications.

 In 1999 the Garden created a new fellowship program for Latin American botanists, the Elizabeth E. Bascom Fellowship for Latin American women in the plant sciences. This program provides travel grants for one to six months of study at the Garden. To find out more about this fellowship and to apply, please go to the Fellowship website.
