Interesting and extensive information. The cover says that about 4,000 species are listed. Each entry includes the botanical name, common names, geographic distribution, an edibility rating, and detailed information on all useable parts of the plant, preparation for use, and toxicity. Uses include traditional eating, medicinal and dyes and fiber. There are many pen and ink drawings but it is not field guide, identification guide or guide for growing. The author also has a "Europe" version.
