0Ames 35590Long Pines #5Amorpha canescens Pursh Montana, United StatesW6Not Available2020Wild materialAmorpha canescens in Montana is known from the southeastern corner of the state by two-pre-1950 collections W. E. Booth #2675 (Carter County) collected in 1948 and W. E. Lockhart #25 (Rosebud County) collected in 1922, (Consortium of Pacific Northwest Herbaria, accessed 20 October 2020)). Currently A. canescens is listed as SH (historical) by the Montana Natural Heritage Program (20 October 2020). According to Vanderhorst et al. (1988), searches by Peter Lesica (1986) followed by Heidel and Dueholm (1995) failed to locate the species. In 2019, the species was discovered by K. Hansen (USFS) on the Sioux Ranger District in the Long Pines Unit (Carter County) during the week of 12 August. The species native range extends from Canada to Texas throughout the Great Plains. This accession represents genetics from the extreme northwestern edge of the species native range and is evidence that the species is present in Montana. In nature, plants of this accession measured approximately 24-36 inches tall with some specimens still flowering at time of collection (12 September 2020). 2107753Ames 35590
