Flowering Plants: Asteraceae, Part 1

Robert H. Mohlenbrock

This, the first of three volumes on the aster family planned for the Illustrated Flora of Illinois series, recognizes 388 species in 119 genera, as well as 20 hybrids and 73 lesser taxa. In Asteraceae, Part 1, author Robert Mohlenbrock presents new and historic information in a clear and easy-to-read style. The volume 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. New nomenclatural combinations are shown for several species. The precise illustrations and detailed information allow for the identification of some of the most difficult to identify plants in the state—goldenrods, asters, artemisias, and fleabanes, among others. Includes 128 original illustrations by Paul Nelson.
Sedges: Carex

Robert H. Mohlenbrock

Sedges: Carex is the fourteenth volume of The Illustrated Flora of Illinois series and the sixth and last volume devoted to monocots-plants that have a single seed leaf, or cotyledon, upon germination.

Since the volume's original publication in 1999, thirty-four additional species of plants have been recognized in Illinois. Some are discoveries from recent field work, some are from more thorough searches of herbaria, and others are from different taxonomic philosophies.

For each 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 detailed discussion of the nomenclature and habitats. Range maps show the county distribution of each species in Illinois. A new and detailed key is provided for identification of the species.
Flowering Plants: Smartweeds to Hazelnuts

Robert H. Mohlenbrock

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.
Flowering Plants: Flowering Rush to Rushes

Robert H. Mohlenbrock

The second edition of Flowering Plants: Flowering Rush to Rushes offers new material, including a preface, seventeen new illustrations of the additional species now known from Illinois, a revised list of illustrations, and an appendix of the additions and changes since 1970 in the identification, classification, and location of the plants included in the first edition. This new edition of the first volume in the multi-volume series of The Illustrated Flora of Illinois—which provides a working reference for the identification and classification of these plant forms in the state—includes flowering rushes, arrowheads, pondweeds, naiads, duckweeds, cattails, bur reeds, spiderworts, and rushes.
Grasses: Bromus to Paspalum

Robert H. Mohlenbrock

Since the publication of the first edition of Grasses: Bromus to Paspalum in 1972, twenty-two additional taxa of grasses have been discovered in Illinois that are properly placed in this volume. In addition, numerous nomenclatural changes have occurred for plants previously discovered, and many distributional records have been added. New keys have been prepared for each genus where additional species from Illinois are known. For new species, full-page illustrations are provided. This second edition updates the status of Illinois grasses. The book features 263 figures from the first edition plus 21 new figures for this edition by Paul W. Nelson.

Genera of grasses included in this work are Aegilops, Agropyron, Agrostis, Aira, Alopecurus, Anthoxanthum, Avena, Beckmannia, Briza, Bromus, Calamagrostis, Cinna, Dactylis, Deschampsia, Elyhordeum, Elymus, Elytrigia, Festuca, Hierochloe, Holcus, Hordeum, Koeleria, Lolium, Milium, Paspalum, Pennisetum, Phalaris, Phleum, Poa, Puccinellia, Sclerochloa, Secale, Sphenopholis, Torreyochloa, Triticum, and Vulpia.
Flowering Plants: Pokeweeds, Four-o’clocks, Carpetweeds, Cacti, Purslanes, Goosefoots, Pigweeds, and Pinks

Robert H. Mohlenbrock

Robert H. Mohlenbrock provides a definitive account of the pokeweed, four-o'clock, carpetweed, cactus, purslane, goosefoot, pigweed, and pink families in Illinois.

Flowering Plants: Pokeweeds, Four-o’clocks, Carpetweeds, Cacti, Purslanes, Goosefoots, Pigweeds, and Pinks is the fifteenth volume of the Illustrated Flora of Illinois series and the ninth devoted to dicots, or plants that have two seed-leaves, or cotyledons, upon germination. Each of the 141 plants is beautifully illustrated by Paul W. Nelson.

Nelson shows the full habitat of the plant and close-ups of various vegetative and reproductive structures that are crucial for the identification of individual species. Each illustration includes detailed drawings of the flowers, fruits, and seeds of the plant covered. Mohlenbrock provides a complete description of each species as well as a discussion of the nomenclature and habitats, and his fifty-three years of experience enable him to present little-known diagnostic features for many species. Range maps show the county distribution of each species in Illinois. Mohlenbrock includes a statement giving the overall range of each species in the United States as well as a detailed key for the identification of the species.

Flowering Plants contains many plants whose obscure flower parts make them exceedingly difficult to identify. The close-up illustrations of these parts will aid the user of the book immensely in identification of the species. Included are several species previously unknown in Illinois.

New illustrations, which include detailed drawings of the flowers, fruits, and seeds are presented for each species covered in this book. Mohlenbrock’s fifty-three years of experience enable him to present little-known diagnostic features for many species.
Grasses: Panicum to Danthonia

Robert H. Mohlenbrock

Since the publication of the first edition of Grasses: Panicum to Danthonia in 1973, twenty additional taxa of grasses have been discovered in Illinois that are properly placed in this volume. In addition, numerous nomenclatural changes have occurred for plants already known from the state, and many distributional records have been added. This second edition updates the status of grasses in Illinois. Paul W. Nelson has provided illustrations for all of the additions.

Because the nature of grass structures is generally so different from that of other flowering plants, a special terminology is applied to them. In his introduction, Robert H. Mohlenbrock cites these terms, with descriptions that make the identification of unknown specimens possible. Mohlenbrock’s division of the grass family into subfamilies and tribes is a major departure from the sequence usually found in most floristic works in North America.

Synonyms that have been applied to species in the northeastern United States are given under each species. A description based primarily on Illinois material covers the more important features of the species. The common names—Paflic Grass, Billion Dollar Grass or Japanese Millett, Thread Love Grass, and Goose Grass—are the ones used locally in the state. The habitat designation and dot maps showing county distribution of each grass are provided only for grasses in Illinois, but the overall range for each species is also given.
Sedges: Cyperus to Scleria

Robert H. Mohlenbrock

This second edition of Sedges: Cyperus to Scleria brings up to date the identification of species of sedges in Illinois (except Carex) since publication of the first edition in 1976.

During the intervening years, several additions to the sedge flora of Illinois have been made, and many new distributional records have been added. Also, a large number of nomenclatural changes have taken place, resulting in several alterations of scientific names. New illustrations have been provided for all of the additions.

In his introductory material, Robert H. Mohlenbrock discusses the morphology of sedges and the habitats where they can be found. Although the semitechnical keys and descriptions are familiar to experienced botanists, he has simplified them as much as possible to accommodate the novice in sedge identification. He has also included a new key to the sedges and to each genus in which additional species have been added.

For each species, Mohlenbrock has provided a description, statement of habitat and range, Illinois distribution map, discussion, synonymy, and line illustrations showing its diagnostic features. Sedges: Cyperus to Scleria contains 128 illustrations.
Ferns

Robert H. Mohlenbrock

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.
Flowering Plants: Nightshades to Mistletoe

Robert H. Mohlenbrock

This sixth volume of dicots contains three orders and eight families. The orders included are Solanales, Campanulales, and Santalales. Within the Solanales are the families Solanaceae, Convolvulaceae, Cuscutaceae, and Polemoniaceae. The Campanulales contain only the family Campanulaceae. The Santalales include the families Celastraceae, Santalaceae, and Viscaceae. As with each volume in this series Mohlenbrock includes a complete plant description, illustrations showing diagnostic features, distribution maps, and ecological notes.
Flowering Plants: Basswoods to Spurges

Robert H. Mohlenbrock

This is the fourth volume in The Illustrated Flora of Illinois devoted to dicotyledons, or dicot plants. Dicots are the greatest group of flowering plants, exceeding the monocotyledons, or monocots. Dicots produce a pair of seed leaves during germination while monocots produce only a single seed leaf.

This volume contains four orders and ten families of dicots. The orders included in this volume are Malvales, Urticales, Rhamnales, and Euphorbiales. Within the Malvales are the families Tiliaceae, Sterculiaceae, and Malvaceae. The families Ulmaceae, Moraceae, and Urticaceae comprise the Urticales. Rhamnaceae and Elaeagnaceae make up the Rhamnales. The Euphorbiales include only the Thymelaeceae and the Euphorbiaceae.
Flowering Plants: Magnolias to Pitcher Plants

Robert H. Mohlenbrock

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 and fifteen families of plants. The orders are the Annonales, Berberidales, Nymphaeales, and Sarraceniales. The fifteen families that comprise them are generally conceded by most botanists to be among the most primitive living plants in the world today. These orders can be characterized generally as woody in the Annonales (except for the Saururaceae and some Aristolochiaceae), herbaceous in the Berberidales (except for the Menispermaceae and some Berberidaceae), aquatic in the Nymphaeales, and insectivorous in the Sarraceniales.

As in previous volumes in this series, the common name, or names, is the one used locally in Illinois. Each species is illustrated, depicting the distinguishing features and the habitat in Illinois.
Flowering Plants: Willows to Mustards

Robert H. Mohlenbrock

This eighth volume in the comprehensive Illustrated Flora of Illinois series is the seventh volume devoted to flowering plants (the eighth volume is devoted to ferns) and the second treating dicotyledons, which include such well-known plants as roses, peas, mustards, mints, nightshades, milkweeds, and asters. The previous volume on dicots, Flowering Plants: Hollies to Loasas, was published in 1978.

In the present volume, Mohlenbrock includes three orders of vascular plants encompassing five families. The orders are Salicales and Tamaricales, of the Salicaceae and Tamaricaceae families, and Capparidales, of the Capparidaceae, Resedaceae, and Brassicaceae families. In all, 44 genera and 117 species are treated in this volume, each species illustrated in detail.
Flowering Plants: Lilies to Orchids

Robert H. Mohlenbrock

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.
