Two thirds of the content of this book is recycled from the error ridden Weeds of the South by the same authors. The numerous mis-identifications and many instances of mis-information are compounded by the fact that the authors chose to use a very technical style in their descriptions, thus requiring a glossary of over 400 technical terms, of which the authors demonstrate a repeated lack of understanding. The only valid purpose of this and the previous Weeds of the South publication, is as a tool to extract funds from the many chemical companies that funded the publications.
