Discussion
Types in herbarium of Columbia University collected by Prof. E. L. Greene, near Golden, Colo., 1873, along streams, in flower ; on river-bank near the Forks of Dismal River, Hooke Co., Nebr., collected by Dr. P. A. Rydberg, July 11, 1893, in fruit. The species is, perhaps, nearest related to C. tomentosa L. Also collected by Mr. R. S. Williams at Columbia Falls, Mont., May 19, 1897 (Herb. N. Y. Bot. Garden).
