Flowering Plants: Willows to Mustards

Foreword

FOREWORD Since its conception in 1960, eight volumes of The Illustrated Flora of Illinois have been published. They include the volume on ferns and seven on flowering plants. Of these seven, five have been devoted to monocotyledonous plants and one thus far to dicotyledonous plants. This is the second volume treating dicots. Several additional volumes on dicots will follow, as well as works on algae, mosses, liverworts, lichens, fungi, and the genus Carex. The concept of The Illustrated Flora is to present every group of plants known to occur in Illinois. A description is provided for each kind of plant, along with illustrations, showing the diagnostic features of each species. Distribution maps and ecological notes are included . Keys to aid in easy identification of the plants are presented. An advisory board was created in 1964 to screen, criticize, and make suggestions for each volume of The Illustrated Flora of Illinois during its preparation. The board is composed of botanists eminent in their area of specialty-Dr. Gerald W. Prescott, University of Montana (algae); Dr. Constantine J. Alexopoulos, University of Texas (fungi); Dr. Aaron J. Sharp, University of Tennessee (bryophytes ); Dr. Rolla M. Tryon, Jr., the Gray Herbarium (ferns); and Dr. Robert F. Thorne, Rancho Santa Ana Botanical Garden (flowering plants). The author is editor of the series and will prepare many of the volumes. Specialists in various groups are preparing the volumes on plants of their special interest. There is no definite sequence for publication of The Illustrated Flora of Illinois. Volumes will appear as they are completed. The author is deeply grateful to the Joyce Foundation whose generous support made possible the production of this volume. Southern Illinois University February 14, 1979 Robert H.
