Although Ewan (1979: 109) discusses the Menzies sheets under the general heading of "Paratype" he meant "syntypes" and we accordingly selected the sheet at BM as the lectotype. This corresponds to Pursh's "pedunculis axillaribus solitariis unifloris." The sterile Lewis and Clark specimen was collected on 27 Jan 1806 at Fort Clatsop, Clatsop Co., Oregon. On the previous day, Lewis wrote a detailed description (Moulton 1990: 237-238). He did not mention flowers.
