one of the best weed bibles out there. great photos, easy to flip through fast and find photos that match what i see in my garden. it answers most questions i have about where it grows, the weed's dimensions, how it differs from look-alikes. yes, it's long on botanical language, to keep it short and concise. but it's a reliable and thorough guide. i have almost worn out my 2 copies of the book. if you don't already have it, i recommend it.
more: great glossary, useful appendices, and conversion of inches to cm measurements on back cover. i use it all the time.
Very good, botanist's field guide to weeds of open fields and disturbed or cultivated land, plus a few trees. Includes photos of seedlings, seeds, flowers, mature plants, roots (sometimes), as well as comparison tables and ID tables. Many weeds are a lot more familiar now, especially grasses and some of the newer invasives. Good quality softcover, worth the price if you really want to be able to identify that stuff.
