Lewis and Clark's 1804 to 1806 expedition to discover a direct water route to the Pacific Ocean resulted in accomplishments never imagined. Although they never found a water route west, they discovered and described more than 40 American Indian tribes, 122 animals unknown to science, and 178 types of plants. In exquisitely detailed watercolor illustrations and intriguing essays, Common to This Country explores more than two dozen of these plants' place in history and their significance. The book skillfully chronicles Lewis' obsession with plant collecting, often in his own words, and botanically accurate watercolors display the salient features often noted in Lewis's journal. This beautiful guide will appeal to natural history buffs and gardeners alike.
