Comments
For Oenothera nuttallii there is one Watershed voucher, from Wagon Wheel Gap (Mineral Co, 1984). Ackerfield (2015) also shows Saguache and Alamosa counties, with no vouchers in SEINet. Recently, the species was photographed in stabilized sand dunes southwest of the entrance to the Great Sand Dunes NPP (iNaturalist observation #227219739. These two Watershed locations would be the only ones in the entire Rio Grande drainage and isolated from the Colorado distribution, which is the northwest third of the state. This evening primrose ranges northward through Wyoming, Montana, South Dakota, North Dakota, and the Great Lakes.
