This field guide, in a size and format useful for educators, naturalists, and life-long learners, is illustrated with excellent photographs, some artistically back lit, and line drawings. Appendices offer keys to the major families, comparisons of new and old taxonomy, selected references, an alphabetized species index by flower color, and a species index. There is also a good glossary, which includes page references back to species and diagrams. Corners help maintain the guide's shape even when repeatedly pulled out of a pack in the field.
