Charles Andreas Geyer

The following is a first pass at organizing the over 455 specimens collected by Geyer in 1838 and 1839. A few explanations and caveats are necessary for any user of the list.

  1. Modern synonymy is not complete and what is given as current name is typically based on annotation found on at least one of the specimens in one of the herbaria that house the specimens. The eventual goal is to provide a current name based on the Flora of the Great Plains (FGP). The presence of Authority after FGP is indicator that FGP name has been assigned. Many of the FGP names have been updated as part of Flora of North America or other names and so more recent sources should be consulted if most current name is desired.
  2. Clicking on the link (note abbreviations are not standard herbarium abbreviations) will provide an image of specimen. Eventually the goal is a larger, high resolution image of each specimen will be available by clicking on "zoom" button but this feature is not currently available. High resolution images for many of these specimens can be obtained at webs sites for NYBG herbarium (NY), Smithsonian (US), Philadelphia Academy (PH), and Missouri Botanical Gardens (MO) web sites. The specimens at these sites can be search by specifying Geyer (or in some cases Nicollet) as collector.
  3. Many of the specimens have an original "brown" label that provides information on habitat or habit, location and collection date. In some cases this information is provided in listing that Torrey provided for collection as Appendix B to the 1843 hydrographical map. Our experience has been that location and date, esp. for 1839 specimens, do not match well so it not clear either when or where specimens were collected. Unfortunately the 1839 Geyer botany journal is missing.
