The Missouri Botanical Garden is one of the world’s top botanical research and conservation institutions. The Garden’s dozens of Ph.D. researchers work to strengthen scientific expertise in developing countries to protect and manage biodiversity before it’s too late.

MoBot Resources

TROPICOS, the world’s largest database of plant information, contains fully web-searchable records for over 900,000 plant names and nearly 2 million specimens. Over 50,000 plant images are also linked to their records in TROPICOS.

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 organisms. As of 1 January 2011 the collection contained 6,231,759 specimens (5,706,547 vascular plants and 525,212 bryophytes).

The Missouri Botanical Garden Library is one of the world’s finest botanical libraries. Founded in 1859 by Henry Shaw, the library is an essential part of the Garden’s research program. It is used in conjunction with the herbarium by Garden research staff, botany students, and visiting scientists from around the world. Horticulturists, landscape designers, historians, biographers, and Garden members also use the library.

William L. Brown Center
The William L. Brown Center (WLBC) is dedicated to the study of useful plants, understanding the relationships between humans, plants, and their environment, and the conservation of plant species and preservation of traditional knowledge for the benefit of future generations.
The WLBC is committed to understanding human relationships with plants and their environment. At present, programs are underway in 12 countries scattered across four continents. Ethnobotanists at the WLBC strive to preserve local knowledge about plants and plant use, even as they work with indigenous peoples to promote sustainable use of existing resources. At the same time, the WLBC is committed to respecting the intellectual property rights of the holders of traditional knowledge. This attitude informs our discovery partnerships with collaborators in pharmaceutical, agricultural, and nutrition research aimed at the development of new drugs, crops, agrochemical, or dietary supplements. Finally, the medicinal plant programs at the WLBC work to develop methods to ensure that botanical ingredients of dietary supplements are correctly identified and characterized to promote high-quality products.
