With excerpts from the journals and nontechnical descriptions, Plants of the Lewis and Clark Expedition mixes history with botany and invites readers to see the wildflowers, shrubs, and trees as the explorers first saw them, from indigo bush in Missouri to feather boa kelp on the Oregon Coast. Phillips has organized the plants into six ecological and geographical regions: Eastern Deciduous Forest, Tallgrass Prairie, High Plains, Rocky Mountains, Columbia Plains, and Pacific Forest. The book includes 315 color photographs, 12 nineteenth-century sketches of Lewis and Clark's specimens, an overview of how the specimens were preserved and their two-hundred-year post-expedition history, an appendix summarizing each specimen's history, a map of each region showing the section of trail where Lewis and Clark found each plant, a glossary, a bibliography, and an index.
