Weeds of the North Central States (North Central Regional Research Publication, No. 281, Bulletin 772)

All the weeds commonly found in the North Central Region, as well as a good many that are less common, are illustrated and described in this book. Detailed pictures have been given for most of the weeds, and whenever possible in the descriptions common terms have been substituted for technical ones. People with a minimum of botanical knowledge should therefore be able to identify almost every weed they are likely to find.
