Meehan (1898: 36) and Cutright (1969: 289) lists this as Dodecatheon meadia L. (Sp. Pl.: 144. 1753). Moulton (in press) refers to it as D. jeffreyi Van Houtte (Fl. Serres 16: 99. 1867). The Lewis and Clark collection was gathered essentially at the type locality of D. poeticum near "the narrows of [the] Columbia R[iver]" on 16 Apr 1806, namely at The Dalles, Wasco Co., Oregon (Moulton, 1991: 125-127). It is somewhat remarkable that this plant, first found in 1806, went undiscovered for over a century. It is doubtful this collection is the basis for the Pursh (1813: 136) attribution of D. meadia "on the Missouri." Lewis saw the species near St. Louis on 17 Apr 1804 (Coues, 1898: 307-308; Moulton, 1986: 209-210), but there is no evidence a specimen was collected.
