Pursh provides an extended description of this new species, stating the plant was found "On the high lands of the Kooskoosky." Both specimens now at PH are annotated 6 Jul 1806 and with phrases alluding to an upland. We can not account for the "July, Aug." date given by Pursh and therefore assume this is an error. Constance (1937: 84) did not distinguish between the two sheets calling both of them the type. Cronquist (in Cronquist et al., 1994: 110) cites the "holotype" as being at PH, but he too fails to distinguish between the two sheets. Meehan (1898: 33) lists this as Eriophyllum caespitosum Douglas (in Lindley, Bot. Reg. 14: ad t. 1167. 1828), a later synonym. The specimens were collected near Kamiah in Idaho Co., Idaho, on 6 Jun 1806 (Moulton, 1991: 338-343).
