From recent-ish Amazon/GoodReads reviews: "I find this book really useful when it comes to identifying weeds. It has great color pictures of every weed in the book, including flowers, seeds, and foliage, as well as descriptive paragraphs, with common names and botanical names. It is only for identification - they don't offer any control information."; "An essential text for identifying weeds, with full color photos of various stages of the plant's growth. Indispensable!"; "Great for invasive non-native species ID, like Noxious weeds. BUT not all plants in this book are 'weeds' many are native species that are a pests to gardeners and farmers. It has great seedling photos, especially for early season ID."
