Robert H. Mohlenbrock – författare

Part armchair travelogue, part guide book, this projected three-volume series - divided into the western, central, and eastern United States - will introduce readers to all 155 national forests across the country. "This Land" is the only comprehensive field guide that describes the natural features, wildernesses, scenic drives, campgrounds, and hiking trails of our national forests, many of which - while little known and sparsely visited - boast features as spectacular as those found in our national parks and monuments. Each entry includes logistical information about size and location, facilities, attractions, and associated wilderness areas. For about half of the forests, Robert H. Mohlenbrock has provided sidebars on the biological or geological highlights, drawn from the 'This Land' column that he has written for "Natural History" magazine since 1984. Superbly illustrated with color photographs, botanical drawings, and maps, this book is loaded with information, clearly written, and easy to use. This volume covers national forests in Alaska, Nevada, Arizona, Oregon, California, Utah, Idaho, and Washington.

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.

A compilation of every known plant in Illinois.This latest edition of Vascular Flora of Illinoisincludes over thirty-four hundred species of flora from Illinois, adding more than 250 newly-recognised 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 recognised 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 relative. 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, environmentalist, and land developers. Those interested in wildflower identification will also find this guide helpful.

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, Volume 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.

Flowering Plants: Asteraceae, Part 3 is the third and final volume in botanist Robert H. Mohlenbrock’s comprehensive sequence of books on the aster family in Illinois. In this volume, Mohlenbrock identifies 128 species in 49 genera with 11 hybrids and 57 lesser taxa. He 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 uses, 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 under 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 overall range for each species is given from the northeastern to the northwestern extremities, south to the southwestern limit, then eastward to the southeastern limit.As important to amateurs interested in wildflower identification as to professional botanists and land planners, this last volume of Mohlenbrock’s Asteraceae is an essential addition to the esteemed Illustrated Flora of Illinois series.
