Steyermark's Flora of Missouri (3-Volume Set)

About this book

With this flora now completed, all three volumes can also be purchased together at a lower price.

Please note that the key to dicot families was initially intended to appear in later volumes, and finally was planned as a supplementary publication. Unfortunately, the supplementary publication of keys did not materialize, and there are no plans to do so in the future. The author of the Flora of Missouri had this response:

"One issue with family-level keys is that the system of family classification underwent radical changes during the life of the Flora project. This has been a problem for all of the big floristic projects, including Flora of North America. It also means that the way plants are placed into families in the Missouri books is fairly unique across the three volumes, which spanned sixteen years. Thus, I cannot recommend an alternative family key that places all of the genera into the same family names and circumscriptions. I would not recommend any of the keys in the various books on Illinois state flora. However, the keys in the Gleason and Cronguist (1991) Manual of Vascular Plants of Northeastern United States and Adjacent Canada at least is relatively user friendly."
