When Pursh proposed Brodiaea grandiflora, the name was superfluous since he included Hookera coronaria in synonymy. The type of Pursh's name, therefore, is the type of H. coronaria, a Menzies collection from California and not the Lewis and Clark sheet listed by Cutright (1969: 405). Meehan (1898: 42) cites this as B. douglasii S. Watson (in Proc. Amer. Acad. Arts 14: 237. 1879), the correct name for the taxon when retained in the genus Brodiaea. Pursh incorrectly says Lewis calls this the "Missouri Hyacinth." The plant was collected on 17 Apr 1806 when the expedition was at The Dalles along the Columbia River. Although the label gives the date as 20 Apr, Lewis describes the plant on 17 Apr and indicates he "preserved a specemine" (Moulton, 1991: 132). The label indicates Lewis called the plant the "Hyacinth of Columbia plains."
