Comments

In the Watershed, Hall's milkvetch has been collected frequently, from open foothills to upper montane, in meadows, forest openings, within cottonwood groves, etc. Hogan and Elliot (2022) note that it is uncommon in the North Cristos. Most of the Upper Basin records are from Francis Ramaley, loosely identified as “Alamosa” and hard to pinpoint; one of his records dated 1930 reads “lakeside scrub zone.” The latest observation is from Moffat (Alamosa Co, iNaturalist #87182335, 15 July 2021). Recently, there have been five iNaturalist observations along the lower reaches of Mosca Creek in Alamosa Co (2018-2022). The plant follows the Rio Grande drainage into New Mexico, but not far. It is confined to Utah, Arizona, New Mexico, and Colorado.
