    The Powell Gardens Herbarium is currently maintained by the loving hands of Paul L. Redfearn, Jr. Ph.D. Emeritus Professor, Missouri State University.
    The Digital Powell Gardens Herbarium Project was created and directed by UMKC Prof. Tamas Kapros, Ph.D. He was assisted by his students. The Powell Gardens Herbarium was inventorized for this website by UMKC Prof. Jakob H. Waterborg, Ph.D.

REQUEST: if you find transcription or interpretation errors from the original Herbarium records into the database, or to other linked resources, please report these by email to the database developer at WaterborgJ@umkc.edu

    The expertise of Dr. Paul Redfearn was instrumental in this project.
    Special thanks go to our student Jakob Fordyce, who provided invaluable assistance in data acquisition.
    The help of Britt Smith and Courtney Masterson in data entry is much appreciated.
    We thank Connie Harclerode, Volunteer Coordinator, for assisting our work at Powell Gardens.

Location Information
  • Many older records identify the location where a plant was collected using the Public Land Survey System (PLSS) of Township, Range and Section.
    The geographical location can be identified using the University of Missouri CARES Map Room tools to review PLSS information and obtain geographical coordinates.

  • Geographical coordinates (often available in newer records or added from descriptions) expressed in Decimal Degrees can be used directly in Google Maps to identify and browse collection locations.
    • Individual Herbarium records with geographical information provide direct links to a Google Maps hybrid view with map-and-satellite information, showing about 1 square mile in the Google map view.
    • Geographical information is approximate, and realistically should be rounded to ~3 decimal places, even if shown with more.
    For more detailed information, click (Geographic Information Systems).

Distribution of plants across Missouri
  • Plants which are present as multiple record specimens in the Powell Gardens Herbarium are shown in-full, if the herbarium record is available as a high-resolution image.
    The Missouri county where the complete record specimen was collected, is shown in RED in the Missouri county map.
    Additional specimens, collected in other Missouri counties, are shown in ORANGE, with collection information shown for each record.

  • Published distributions across Missouri counties of plants in this Powell Gardens Herbarium collection are linked from the Atlas of Missouri Vascular Plants, DOT MAP EDITION, by Wallace R. Weber, William T. Corcoran, Mark Brunell & Paul L. Redfearn, Jr. (Revised September 2006).
    The presence of plant species in Missouri counties, established by Julian Steyermark, are shown in darker GREEN; later identifications are shown in lighter GREEN.

  • Distributions of plants across the U.S and beyond are generally available through the USDA Plants Database link provided through the USDA Symbol.
    Selecting the state of Missouri in these distribution maps provides plant distribution across counties, if data are available.
    Single plant or record pages provide a direct link to the Missouri county distribution information for those plants considered to be Missouri Plants, native or naturalized.
    For plants not considered to be 'Missouri Plants', no Missouri county distribution information is offered.
