Meehan (1898: 24) lists this sheet, Lewis 59, as Gutierrezia euthamiae (Nutt.) Torr. & A. Gray (Fl. N. Amer. 2: 193. 1842). This name is based on Brachyris euthamiae Nutt. (Gen. N. Amer. Pl. 2: 163. 1818), an illegitimate superfluous name for Solidago sarothrae. Being superfluous, the type of Nuttall's name is therefore the type of S. sarothrae and not a Nuttall specimen as suggested by Lane (1985: 24). The Lewis specimen was collected on the lower part of the Big Bend of the Missouri River, Buffalo Co., South Dakota, on 19 Sep 1804 (Moulton, 1987a: 469).
