CARDAM INE LEIBERGII Holz. Cont. U. S. Nat. Herb. 3 : 212. 1895.
This species was rediscovered by myself in 1895, but only a few specimens were preserved. It was growing in canons at two widely separated stations, viz., near Lima, in Beaverhead County, no. 2663, and in Bozeman Caiion in Gallatin County, no. 2664. It resembles a depauperate C. Brewcri, but differs in the much thicker and more angular toothed leaves. The latter species is very common in Montana.
