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.).

Visitors should try to arrive at the Garden during normal working hours. On arrival, come to the reception area on the 2nd floor of the Bayer Center (4500 Shaw Blvd., two blocks west of the main Garden entrance) to register with the Herbarium Secretary. A brief orientation will be made to the facilities and collections at that time. If arriving after-hours, please go the main entrance of the Garden at 4344 Shaw Blvd. and contact a Security Officer.


The Garden maintains inexpensive accommodations close to the Herbarium and Garden for research visitors. The Garden's guesthouses, Trelease House or Anderson House, have individual apartments that are large, comfortable, completely furnished, with kitchen facilities. The guesthouses are named in honor of William Trelease and Edgar Anderson, former directors of the Garden. For all questions regarding guest housing, please email herbarium@mobot.org.

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.
