Flowering Plants: Smartweeds to Hazelnuts

For each plant known to occur in Illinois, Mohlen­brock and Thomson have included a complete de­scription, illustrations (106 in all) showing diagnos­tic features, distribution maps (95), and ecological notes. The authors also present keys to aid in the identification of the plants.

This volume includes one family--the Polygonaceae--from the large order Chenopodiales, and two orders in their entirety--the Hamamelidales with two families and the Fagales with three families.
