The Pursh name, long in use, is technically superfluous as he included Lilium camschatcense L. (Sp. Pl.: 303. 1753) via Willdenow (Sp. Pl. 2: 89. 1799) in synonymy. Furthermore, he goes on and states the Lewis and Clark plant is L. camschatcense and he "had no idea of finding it under Lilium." No plate was published in the Flora but Pursh states he "made a drawing and description under the above name [F. lanceolata] for the Travels of Lewis and Clark." The currently available name for the taxon is Fritillaria affinis. A handwritten Lewis label on one specimen (PH-LC 93) indicates he collected this species on 10 Apr 1806 as the party worked their canoes up the rapids around Bradford (then "Bryant") Island, Multnomah Co., Oregon, in the Columbia River (Moulton, 1991: 101-104). It is interesting to speculate on the scene that Lewis must have presented, carefully collecting this checker lily while others labored to pull boats up stream through cascading waters.
