Understanding the flowering plants of any region begins with the recognition of families. This remarkable volume, created to serve students, professionals, and other plant enthusiasts, covers 130 temperate to tropical families common in North America with detailed illustrations and modern referenced commentaries. Each family discussion includes a diagnosis and summary of characteristics, distribution data, important economic members, and pollination ecology. The book's most striking feature is Zomlefer's 158 original pen-and-ink plates depicting intricate dissections of 312 species.The content of the family discussions is geared to readers who have completed one introductory biology course. For readers less familiar with botanical terminology, Zomlefer provides an illustrated glossary of 551 terms with more than 300 drawings. Other important tutorial features are twenty-two detailed charts that compare pertinent characteristics of certain related plant groups and a general chart that summarizes the salient features of the families covered in the text. Both amateurs and professionals will particularly enjoy the chapter on examining, dissecting, and sketching live material.
