Acanthaceae to Myricaceae
Water Willows to Wax Myrtles
Robert H. Mohlenbrock
Southern Illinois University Press, 2008

Veteran botanist, scientific author, and professor Robert H. Mohlenbrock brings the full depth of his expertise and scholarship to his latest book, Acanthaceae to Myricaceae: Water Willows to Wax Myrtles, the third of four volumes in the Aquatic and Standing Water Plants of the Central Midwest series. This easy-to-use illustrated reference guide covers aquatic and standing water plants for the states of Iowa, Illinois, Indiana, Ohio, Kansas, Missouri, Nebraska, and Kentucky (excluding the biologically distinct Cumberland Mountain region of eastern Kentucky), from spearmint to wintergreen, from aster to waterwort.

The volume identifies, describes, and organizes species in three groups, including truly aquatic plants, which spend their entire life with their vegetative parts either completely submerged or floating on the water’s surface; emergents, which are usually rooted under water with their vegetative parts standing above the water’s surface; and wetland plants, which live most or all of their lives out of water, but which can live at least three months in water.

Mohlenbrock lists the taxa alphabetically, and within each taxon, he describes the species with the scientific names he deems most appropriate (indicating if his opinion differs from that of the U.S. Fish and Wildlife Service), common names, identification criteria, line drawings, geographical distribution, habitat description, and official U.S. Fish and Wildlife Service wetlands designation as described by the National Wetland Inventory Section in 1988.

Acanthaceae to Myricaceae is an essential reference for state and federal employees who deal with environmental conservation and mitigation issues in aquatic and wetland plants. It is also a useful guide for students and instructors in college and university courses focusing on the identification of aquatic and wetland plants.

Robert H. Mohlenbrock
Southern Illinois University Press, 2005

The first in a series of four illustrated guides to identifying aquatic and standing water plants in the central Midwest, this convenient reference volume covers the 183 species of Cyperaceae. Robert H. Mohlenbrock includes three types of plants: submergents, those that spend their entire lives with their vegetative parts either completely submerged or at least floating on the water’s surface; emergents, which are typically rooted underwater with their vegetative parts standing out of water; and a third category of plants that live most of their lives out of water, but which may live in water at least three months a year.


Mohlenbrock provides descriptions, illustrations, and ways to identify any plant in the sedge family (Cyperaceae) in the states of Kentucky (except for the Cumberland region), Ohio, Indiana, Illinois, Iowa, Missouri, Kansas, and Nebraska. With taxa arranged alphabetically, the volume is well organized and easy to use. In addition, basic synonymy, description, distribution, comments, and line drawings that show the habits and distinguishing features for each plant. Habitat and nomenclatural notes are also listed, as are the official wetland designations given by the U.S. Fish and Wildlife Service.


Cyperaceae is a useful standard reference for state and federal employees who deal with aquatic and wetland plants and environmental conservation and mitigation issues and an essential guide for students and instructors in college and university courses where the identification of aquatic and wetland plants is emphasized.

Distribution of Illinois Vascular Plants
Robert H. Mohlenbrock and Douglas M. Ladd
Southern Illinois University Press, 1978
This new distribution list— the first since Winterringer and Evers (1960)— brings up-to-date every vascular plant known to occur in Illinois as a native, naturalized, or escaped species, some 3,001 taxa of vascular plants within the boundaries of the state.
 
There are 251 pages of distribution maps included in this book. The plants are arranged alphabetically by genus, and under each genus alphabetically by species. The nomenclature follows Mohlenbrock, Guide to the Vascular Flora of Illinois (1975).
 
In addition, a list of synonyms applied to Illinois taxa by Fernald (1950), Gleason (1952), and Jones (1963) follows the distribution maps.
 
Finally, in order to gain an under­standing of relationships of the plants in the Illinois flora, all 3,001 taxa are arranged in a phylogenetic sequence at the end of the book.

Ferns
Robert H. Mohlenbrock
Southern Illinois University Press, 1999

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.

Robert H. Mohlenbrock includes three types of plants: submergents, those that spend their entire lives with their vegetative parts either completely submerged or at least floating on the water’s surface; emergents, which are typically rooted underwater with their vegetative parts standing out of water; and a third category of plants that live most of their lives out of water, but which may live in water at least three months a year.

With taxa arranged alphabetically, the volume is well organized and easy to use. In addition, basic synonymy, description, distribution, comments, and line drawings show the habits and distinguishing features for each plant. Habitat and nomenclatural notes are also listed, as are the official wetland designations given by the U.S. Fish and Wildlife Service.

Filicineae, Gymnospermae, and Other Monocots, Excluding Cyperaceae is a useful standard reference for state and federal employees who deal with both aquatic and wetland plants and environmental conservation and mitigation issues. It is furthermore an essential guide for students and instructors in college and university courses focusing on the identification of aquatic and wetland plants.

Basswoods to Spurges
Robert H. Mohlenbrock
Southern Illinois University Press, 1982

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 Rush to Rushes
Robert H. Mohlenbrock
Southern Illinois University Press, 2006

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.

In his introduction, Robert H. Mohlenbrock defines terms and procedures used in the identification and classification of this group of flowering plants referred to as monocotyledons—plants that produce upon germination a single cotyledon or seed-leaf and are often identified by their tall, slender, grass-like leaves. He outlines the life histories and morphologies of the representative monocots and illustrates the plants’ habits and frequencies in Illinois.

Geared to the amateur as well as the professional botanist, the volume includes a glossary of definitions and identification keys to classify the plants according to order, family, genus, and species. The identifying characteristics of each descending class are also 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. Among the 125 illustrations are detailed sketches of the important features of each species and maps indicating the geographical locations of each species in Illinois.

Lilies to Orchids
Robert H. Mohlenbrock
Southern Illinois University Press, 1970

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.

Robert H. Mohlenbrock
Southern Illinois University Press, 2001

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.

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.

Southern Illinois University Press, 2010

In this fourth and final installment in the Aquatic and Standing Water Plants of the Central Midwest series, veteran botanist Robert H. Mohlenbrock identifies aquatic and wetland plants in eight central Midwestern states, which include Iowa, Illinois, Indiana, Ohio, Kansas, Kentucky (excluding the Cumberland Mountain region), Missouri, and Nebraska.

Nelumbonaceae to Vitaceae: Water Lotuses to Grapes contains 346 highly informative and technically accurate illustrations as well as ecological information, nomenclature, and keys for plants in the aforementioned families, including white water lily, fireweed, smartweed, mild water pepper, hawthorn, and wild strawberry. Mohlenbrock identifies and describes each plant in concise and readable prose and indicates its usual habitats and the states in which it occurs.

As with previous volumes, Mohlenbrock organizes each species into three groups: truly aquatic plants, which spend their entire life with their vegetative parts either completely submerged or floating on the water’s surface; emergents, which are usually rooted under water with their vegetative parts standing above the water’s surface; and wetland plants, which live most or all of their lives out of water.

With Nelumbonaceae to Vitaceae, Mohlenbrock completes the four-volume series organizing and identifying wetland plants in the central Midwest. The botanical series will aid many, from teachers and students to state and federal employees, focused on conservation efforts and mitigation issues.

Southern Illinois University Press, 2011
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.

Carex
Robert H. Mohlenbrock. Illustrated by Paul Nelson
Southern Illinois University Press, 1999
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.

Southern Illinois University Press, 2001

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.

Vascular Flora of Illinois
Robert H. Mohlenbrock
Southern Illinois University Press, 2002
The first flora of Illinois was prepared in 1846 by Dr. Samuel B. Mead, a physician from Augusta, Illinois. Between 1846 and 1963, several people published plant lists and floras for various parts of Illinois. In 1975, Robert H. Mohlenbrock published his first edi­tion of Guide to the Vascular Flora of Illinois, followed by a second expanded and revised edition in 1986.

 

This latest Vascular Flora of Illinois includes over thirty-two hundred species, an increase of almost three hundred since 1986. In addition, for the first time, taxa below the rank of species are recognized and may be identified by keys. Investigating seldom-visited patches of prairies, wetlands, and forested canyons, Mohlenbrock has added several native spe­cies to this flora. And while there has been extensive exploration for plants, Mohlenbrock has also re­searched the herbaria in an attempt to verify previous reports of records of Illinois plants.

 

Because of a reinterpretation of existing genera, the number of genera of Illinois plants has increased markedly. Recent biosystematic techniques have be­gun to substantiate the genera that botanists such as John Kunkel Small, Per Axel Rydberg, and Edmund C. Greene proposed nearly a century ago.

 

The sequence of groups in this book is ferns, coni­fers, and flowering plants, with dicotyledons 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 a common name if one is gener­ally used in Illinois. He follows this by an indication of flowering time for flowering plants and of spore-production time for ferns and their relatives. He also provides a habitat statement and a general comment on distribution in Illinois for each taxon. Synonyms for some other scientific names used previously for a taxon appear in italics. This book contains indexes both for common names and for family and genus names.

Southern Illinois University Press, 2013

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.
