The USF Herbarium was established as a research and teaching collection in 1958 by George R. Cooley, two years after the founding of the University of South Florida. The USF Herbarium is the second largest collection in Florida, the seventh largest in the southeastern United States, and ranks in the upper third of the world's herbaria in size. The herbarium contains approximately 280,000 specimens, consisting of about 260,000 specimens of vascular plants, 14,000 algae, 2,800 bryophytes, 1,300 lichens, and 300 macrofungi. The collection contains approximately 400 type specimens. The herbarium is richest in specimens from Florida (~40%), with additional holdings from North America north of Mexico (~35%), Latin America and the West Indies (~15%), and the Eastern Hemisphere (~10%). Specific groups well represented in the herbarium include Acanthaceae, Apocynaceae, Begoniaceae, Bromeliaceae, Fabaceae, Orchidaceae, and pteridophytes (ferns).

Data Records

The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 238,875 records.

2 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

Occurrence (core)

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.


The table below shows only published versions of the resource that are publicly accessible.

Project Data

No Description available

Title Atlas of Florida Plants
Study Area Description Florida has over 4,700 species of native or naturalized plants in Florida, including over 4,300 species of vascular plants and over 400 species of bryophytes (plants known only from cultivation are not included). The Atlas of Florida Plants is a joint effort by the Institute for Systematic Botany, the University of South Florida, and the USF Water Institute to provide a comprehensive searchable database of plants in the state of Florida. This website also provides access to the USF Herbarium, which houses over 280,000 specimens from around the world (about 50% of these are databased and available online).
