The following table provides images in support of the keys to plants in the three volume book:
Voss, Edward G. Michigan Flora. Cranbrook Institute of Science.
Part I. Gymnosperms and Monocots. Bulletin 55. (1972)
Part II. Dicots (Saururaceae - Cornaceae). Bulletin 59. (1985)
Part III. Dicots (Pyrolaceae - Compositae). Bulletin 61. (1996)

Until such time as a "Flora of Wisconsin" is available, Michigan Flora is an essential resource for botanists in Wisconsin. The books are of excellent quality and very affordable. They may be purchased at: http://herbarium.lsa.umich.edu/website/publications/glb_catalog.html

I am strongly opposed to"picture matching" as a means of identification of unknown plants. The answers arrived at in this manner are closer to a guess than to a reliable determination. Accurate identifications generally require the use of a dichotomous key. However, it has been my experience that beginners may have difficulty visualizing terms used in plant keys. A carefully chosen image can sometimes help as students learn the characters. It is in this spirit that the following illustrations are provided.
