Flowers fragrant, solitary at the end of short twigs, 3⁄4 in. wide, white or pale yellow; petals five, obovate; calyx funnel-shaped at the base, with five lobes, glandular and downy like the flower-stalk; stamens numerous.

Native of the S.W. United States from Nevada, Utah, and Colorado to S. California, also of N. Mexico; discovered by Howard Stansbury in 1852 during his expedition to the great Salt Lake of Utah. This species and C. mexicana D. Don, are closely allied. Jepson, the Californian botanist, made it a variety of C. mexicana, and this status is accepted by Munz in A California Flora (1959). The calyx of C. mexicana is more bell-shaped than funnel-shaped. Both need the sunniest position that can be given them.
