Flowers 4–7 mm; perianth bright yellow. 2n = 80.

Discussion
Variety nevadense is widespread and often common in California, Nevada, and southeastern Oregon. It is the common expression of the species at middle and lower elevations on the eastern slope of the Sierra Nevada and the Great Basin portion of the Intermountain West. In the northern Sierra Nevada of California, and in the Granite Range of Washoe County, Nevada, it merges with var. modocense. At higher elevations in the Sierra Nevada, it grades into var. covillei. The Nevada sulphur flower occasionally is found in cultivation.
A single collection from the Charley Johnson Canyon, Canyon Mountains, eastern Millard County, Utah (Goodrich 15832, BRY), may well be var. nevadense, but it needs to be confirmed.
