A Collaborative Database of the Vascular Plants from the Missouri Plateau

The term collaborative is important to note in the title of the database. This work combines specimen data for our region from 26 herbaria and could not have been done without the support and cooperation of numerous curators/collection managers (listed below). Nor could this project have been completed without funding from the National Fish and Wildlife Foundation and the National Science Foundation.

About 200,000 vascular plant specimens from the Missouri Plateau (Fig. 1) are included in the current database.

All label data from vouchered specimens have been carefully entered. Latitude, longitude and elevation have been added to localities in the database where possible. At times it was not possible to obtain accurate longitude/latitude data for older specimens that lack sufficient location data.

Scientific names used in the database are taken from the USDA Plants website ( or the Flora of North America (

The word “species” is frequently used in our database to refer to the specific epithet. We know this is not correct, but is it commonly used and its meaning is clear to most people.

We hope that botanists, ecologists, land managers and the public will use this database.


Species noted as sensitive by the USDA Forest Service or the South Dakota Department of Game, Fish and Parks or the Wyoming Natural Heritage Inventory are available to the public on this database, but the location information for these collections is withheld. A list of the sensitive species can be obtained if you click here.

Researchers who need access to locality data for these species can contact Grace Kostel, Database Manager ( Comments and suggestions are appreciated and can be directed to Grace Kostel or Mark Gabel (

The National Fish and Wildlife Foundation is gratefully acknowledged for their generous financial support that allowed us to complete the database on the grasses of the region that was the foundation for the remainder of the work.

We are eager to acknowledge the National Science Foundation for their support through grant number 50545102 and 0847960 for herbarium renovation and the bulk of the databasing project.

The South Dakota Humanities Council grant has allowed us to summarize the history of the Herbarium and document the correspondence of Herman Hayward relating to his botanical exploration of the Black Hills.

We especially thank Ron Hartman at RM for permission to use their database system in an earlier version of this database.

The curators/managers of the herbaria included in the database are thanked for their gracious hospitality upon our visits to their facilities and their willing cooperation on this project.
