Floras and field guides are two kinds of plant identification references.
A "flora" is a book that lists plant species growing within a region and provides taxonomic keys to the species. Some floras specialize, covering only certain groups of plants or genera. Experience with "keying out" species is usually necessary to use a flora effectively.
A field guide usually uses photographs and/or illustrations to help with plant identification. While these guides are easy to use, some species are omitted. Nonetheless, the visual aids in a good field guide are helpful.

This checklist is out of print and hard to find. If you have one, hang onto it! Although the taxonomy is somewhat dated, the distribution maps are very useful.
For an up-to-date checklist of Minnesota's plant species, contact Dr. Anita Cholewa at the Bell Museum Herbarium.
The Minnesota County Biological Survey (MCBS) collects data on the location and ecology of rare plants, animals, and native plant communities. To date, 74 of Minnesota's 87 counties have been surveyed. The Minnesota DNR publishes a wide variety of books and reports on Minnesota's ecology, vegetation, and plants.
These resources will help you plan trips to visit plants. Remember: don't pick flowers or collect plants in local, State, or National Parks or State Scientific and Natural Areas. For more information on where and how to collect plants, visit our "Making a plant collection" page.
