The first step in deciding how to solve a weed problem is to correctly identify the weed species. It is for this purpose that this guide has been prepared, and the intended users are research workers, weed specialists, agricultural extension agents, and others interested in weeds and their control. This book will help to identify some of the nation's more common and important weeds infesting lawns, gardens, crops, pastures, ponds, and other areas." Originally published in 1970, this new edition has been updated to reflect the many taxonomic changes in both family assignments and in genus and species names. The guide has been completely reformatted for easier use, with plants presented in alphabetical order by plant family. Detailed illustrations by preeminent botanical illustrator Regina Olson Hughes depict both the overall plant as well as its flowers, fruits, and seeds. County-level distribution maps have been added for each of the more than 200 species treated. Our hope is that The New Common Weeds of the United States will be a valuable reference for anyone wanting to learn more about our weed flora and for those working to preserve our native plants and their habitats.
