Sedges: Carex is the fourteenth volume of the Illustrated Flora of Illinois series and the sixth and last volume devoted to monocots, or plants that have a single seed-leaf, or cotyledon, upon germination. For each of the 159 species of Carex in Illinois, there is a full illustration showing the habit of the plant and close-ups of various vegetative and reproductive structures that are crucial for the identification of the individual species. There is also a complete description of each species as well as a discussion of the nomenclature and habitats. Range maps show the county distribution of each species in Illinois. A detailed key is provided for identification of the species.



Unique in several respects, Carex is by far the most numerous genus of plants in Illinois. Because of the vast number of species, the similarity of many of the species, and the relatively small size of the critical reproductive structures, the members of this genus are extremely confusing to identify. This book, with its detailed descriptions, key, and precise illustrations, should aid the interested person in the identification of these plants.



Since more than three-fourths of the species of Carex in Illinois are inhabitants of wetlands, an understanding of the genus is critical for those working in wetlands. Amateur and professional botanists will find the information extremely valuable, as well as environmental and conservation groups, garden clubs, farm bureaus, home extension groups, scout organizations, and school libraries. Persons working in natural areas programs and in rare and endangered species programs and those working on environmental impact assessments and wildlife management projects will also find the information pertinent.



 

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.
