It is curious that Lewis and Clark collected so few grasses and apparently no sedges or rushes. Both men surely appreciated the importance of forage grasses given their agricultural background. This specimen was found "On the plains of Columbia" according to the Pursh label, but on 10 Jun 1806 when the expedition was traveling along the trail toward Weippe Prairie northeast of Kamiah in Clearwater Co., Idaho (Moulton, 1993: 7-14). Lewis mentions numerous plants in his journal of this date, but no grasses. He does discuss several graminoids on 5 Jun, however, but none seem to be this species (Moulton, 1991: 334-338). Meehan (1898: 45) lists the specimen as Festuca ovina L. (Sp. Pl.: 73. 1753), a closely related species with a nearly circumboreal distribution.
