This volume, the eighth devoted to flowering plants in the Illustrated Flora of Illinois series, is the third of several devoted to dicotyledons, which include such well-known plants as roses, peas, mustards, mints, nightshades, milkweeds, and asters. Mohlenbrock here represents four orders (Annonales, Berberidales, Nymphaeales, and Sarraceniales) and fifteen families of plants. As in previous volumes in this series, the common names are those used locally in Illinois. An illustration of each species depicts the distinguishing features and the habitat in Illinois.
Robert H. Mohlenbrock taught botany at Southern Illinois University Carbondale for thirty-four years. Since his retirement in 1990, he has served as senior scientist for Biotic Consultants, teaching wetland identification classes around the country. Among his more than sixty books are Vascular Flora of Illinois and Field Guide to U.S. National Forests.
