List of species described by the Lewis and Clark Expedition
Lewis and Clark expedition encountered 174 plants and 134 species and subspecies of animals new to science. Lewis lost the notes about the specimens but analyses and detailed scientific descriptions of the specimens were performed by others. Lewis hired Frederick Pursh in Rhode Island to review the plant collection and describe and publish the results, which Pursh did in 1828. Lewis described and published none of the plants he collected in the Western America.
