Book Description
This book will be of particular interest to those interested in applied fields of biology, such as conservation, forestry, and wild life. The southern twelve counties of Illinois, a total of 4,355 square miles, comprise the area covered in this book. It is an area in which both northern and southern flora specimens abound. A wide variety of plant species grow in this area, and nearly 200 new plants not formerly identified with this area have been included in the listings. Especially valuable to amateur botanists, the book is an important manual in identifying the plants that make up the native scenery of this region. Seventy-seven illustrations aid in identifying and understanding the plant communities.

Book Description
Since the publication of the first edition of Smartweeds to Hazelnuts in 1987, thirteen additional species and one hybrid have been discovered in Illinois. In addition, numerous nomenclatural changes have occurred for plants already known. This second edition updates the status of the Polygonaceae, Hamamelidaceae, Platanaceae, Fagaceae, Betulaceae, and Corylaceae in Illinois. Each of the newly discovered species has been added and is fully illustrated. Updated nomenclature as well as Illinois distributional data are included for each species. In addition to the fourteen new plant illustrations, the appendix contains new information on the descriptions and the geographical locations of plants in the first edition, and revised identification keys. Robert H. Mohlenbrock and Paul M. Thomson Jr. have included a complete description, illustrations showing diagnostic features, distribution maps, and ecological notes for each plant included in this volume. This new edition will be invaluable to scholars of botany as well as laypersons interested in observing plants in their natural habitat.

Book Description
Perhaps no other group of plants attracts more interest among both professional and amateur botanists than ferns. As early as 1846, when one of the first lists of Illinois plants was published, sixteen species of ferns were already known in the state. The longtime interest of a great many people makes the distribution of ferns better known than that of any other group of plants in Illinois. This detailed account of ferns and fern-allies was first published in 1967 as the first volume in the series The Illustrated Flora of Illinois. Eminent botanist Robert H. Mohlenbrock has now revised Ferns to include twenty-five additional taxa of ferns that have since been discovered in Illinois. In addition, numerous nomenclatural changes have occurred for plants already known in the state. The introductory information of Ferns includes discussions of the morphology and life history of the ferns and fern-allies, the taxonomic history of the group in Illinois, and the habitats where they can be found. The semitechnical keys and descriptions, familiar to the professional botanist, have been simplified for the novice and are accompanied by a glossary and a profuse use of illustrations. A new key has been included for the additional ferns. Two general keys enable the reader to identify the order and the genus of the fern or fern-ally in question. One of these is designed for use with specimens that have sporangia; the other is for use with sterile specimens. The keys are composed of a hierarchy of characteristics for determining the order, family, and genus of any given specimen. Once a genus is ascertained, the reader can apply its key to more than one species of the same genus. Each species has its own description, statement of habitat and range, Illinois distribution, map, discussion, synonymy, and full-page line illustration showing its diagnostic characteristics.

Book Description
This latest edition of Vascular Flora of Illinois includes over thirty-four hundred species of flora from Illinois, adding more than 250 newly-recognized plants to this definitive collection. Because cataloguing our heritage is foremost in importance among naturalists, this book compiles essential information about plants in Illinois. Mohlenbrock includes all known taxa native to Illinois either at present or in the past and all non-native vascular plants that grow spontaneously and appear able to maintain themselves year after year without cultivation. The sequence of groups in the guide is ferns, conifers, and flowering plants, with cotyledons given before monocotyledons. Within each group, the families are arranged alphabetically, as are the genera within each family and the species within each genus. For each taxon recognized in this book, Mohlenbrock gives us a common name if one is generally used in Illinois. He follows this with an indication of flowering time for flowering plants, and of spore-production time in the case of ferns and their relatives. He also provides a habitat statement and a general comment on distribution in Illinois for each taxon. Containing information on Illinois flora not available anywhere else, this fourth edition of Vascular Flora of Illinois is essential for ecologists, environmentalists, and land developers. Those interested in wildflower identification will also find this guide helpful.

Book Description
A continuation of “The Illustrated Flora of Illinois” series, this volume features Illinois flowering plants. This series is designed to provide a working reference for the identification and classification of all the plant forms found in the state. This series is the first of its kind, as no other study of this sort has been undertaken in any other state, and as such, is an unparalleled contribution to its field. In his introduction to this volume, Mr. Mohlenbrock discusses some of the terms and procedures used in the identification and classification of the plants. He outlines the life histories and morphologies of some of the representative monocots, and also illustrates some of their habits and frequencies in Illinois. Since these volumes are meant to be used by the amateur as well as the professional botanist, the methods and terms used in the text are explained. The directions for the use of the various identification keys are given so that even the novice plant lover will be able to identify the species encountered. For the uninitiated, a glossary is provided which gives definitions for all terms that might be unfamiliar. All necessary aids to identification are included in the text itself. The identification keys make it initially possible to classify the plants according to order, family, genus and finally, species and the identifying characteristics of each descending class are given in detail. The morphology of each species is outlined, along with data on frequency of occurrence, related soil and climate conditions and history of past collections, and history of past collections. An illustration showing the more important features of the species in detail is included with the description, as well as a map indicating its geographical locations in Illinois. This book will be invaluable to students, teachers and professionals; particularly those who are interested in observing the plants in their natural habitat. Those who use it will find it possible to obtain a broad view of changing plant forms as they relate to soil and climate variations throughout the state. And it will provide a delightful diversion for all who enjoy viewing beautiful forms in nature. A walk through the forest will become an opportunity for discovery and appreciation.
