In this second volume on the aster family, botanist Robert H. Mohlenbrock recognizes 133 species in 42 genera, as well as 7 hybrids and 29 lesser taxa. Flowering Plants: Asteraceae, Part 2 provides an easy-to-use key to the genera and species and a complete description and nomenclatural and habitat notes for each plant, including its usefulness, if applicable. The book details the most important features of the species and includes common, locally used names. Synonyms that have been applied to species and lesser taxa in Illinois are given for each species.
In addition, Mohlenbrock has identified the overall range for each species in Illinois, compiled from various sources, including examinations of herbarium material and Mohlenbrock’s own field studies. The range is given from the northeastern to the northwestern extremities, south to the southwestern limit, and then eastward to the southeastern limit.
As important to amateurs interested in wildflower identification as to botanists and land planners, this second volume of Mohlenbrock’s Asteraceae is an essential addition to the esteemed Illustrated Flora of Illinois series.
