Oenothera pallida Lindl. var. pallida (syn. O. pallida subsp.pallida).May 26, 2012, Wasatch foothills rainy day, Olympus Hills Park, 4850 ft. elev.The park has a nice and very variable goup of O. pallida (some might be from the misguided use of seed mixes in the early days when the park was first designated). While it is present not too far away at roughly the Bonneville Shoreline level, O. cespitosa is not present in the park.
