  n August 22, 1805, interpreter and hunter George Drouillard was scouting through the cove west of Camp Fortunate, near the forks of the Beaverhead River, when he came upon a half-dozen Shoshone Indians—a young man, an old man, a boy, and three women—and carried on a friendly exchange of pleasantries via sign language. Suddenly a young man snatched Drouillard's gun from the ground where he had left it when he walked off to catch his own horse. The whole party mounted up and, leaving their collective baggage on the ground, raced off in the direction of Lemhi Pass, with Drouillard in hot pursuit. After a chase of some ten miles, two of the women's horses gave out and Drouillard was able to overtake the fleeing party. He wrested his gun from the young man, and the Shoshones raced on toward the pass. Back at Camp Fortunate the next day, Captain Lewis wrote down the rest of the story:
| Drewyer now returned to the place they had left their baggage and brought it with him to my camp. It consisted of several dressed and undressed skins; a couple of bags wove . . . of the bark of the silk-grass, containing each about a bushel of dryed service burries, some chokecherry cakes, and about a bushel of roots of three different kinds, dryed and prepared for uce, which were foalded in as many parchment hides of buffaloe. |
One of the roots proved to be a vegetable highly prized by Indians throughout the inland northwest. Lewis noted the specimen was | much mutilated but appeared to be fibrous. The parts were brittle, hard, of the size of a small quill; cilindric and as white as snow throughout, except some small parts of the hard black rind which they had not seperated in the preperation. This the Indians with me informed me were always boiled for use. I made the experiment, and found that they became perfectly soft by boiling, but had a very bitter taste, which was naucious to my pallate, and I transfered them to the Indians who had ate them heartily. |
This was the root that French trappers were soon to call racème amer—"root [which is] bitter." When the expedition returned to the mouth of Travelers' Rest Creek in the lower Bitterroot Valley, on its return trip early in July of 1806, Lewis collected some whole plants of the species. Back in Philadelphia, he turned them over to one of the leading botanists of the day, Frederick Pursh (1774-1820), for official classification. In honor of Captain Lewis, Pursh established a new genus in the purslane family, Latinizing it as Lewisia (lew-EE-see-uh), and designating this species rediviva (red-ih-VEE-vuh). -- 5/2003; rev. 6/2012 ReferencesPaul Russell Cutright, Lewis and Clark: Pioneering Naturalists (Lincoln: University of Nebraska Press, 1969).
