This is practical guide to the identification and biology of submerged, floating leaved, and emergent aquatic weeds in the Western United States. The book contains a full description of 89 species representing 36 plant families, and another 96 plants compared as similar species. There is at least one photograph each of 171 aquatic plant species. The book contains quick identification tables, several keys, and an illustrated glossary. 
This new weed identification book has been in the making for over six years. It is the most comprehensive weed identification book yet produced in the United States. It contains over 3000 color photos of infestations and whole plants as well as close-up photos of flowers, seedlings and seeds. DiTomaso and Healy offer comprehensive descriptions and photographs of over 750 weed species in the book. Detailed information about seedlings, mature plants, flowers, fruits, roots, germination and propagation characteristics and descriptions of similar species simplify the quick and accurate identification of a weed.
