Same sheet as PH-LC 202b. The specimen was collected near Kamiah in Idaho Co., Idaho, on 5 Jun 1806. Lewis mentions several plants in his journal on this day, but not this species (Moulton, 1991: 335). Given the fine technical details that distinguish this species from the next (No. 177 below), it is not surprising that Pursh did not recognize he had a second new species of Sedum. It is equally understandable why others, save a monographer, failed to note the differences as well (e.g., Meehan, 1898: 28; Cutright, 1969: 419; Moulton, in press).
