Discussion

Variety alatum is widespread and often common from southeastern Wyoming and adjacent southwestern Nebraska southward through eastern Utah, Colorado, and western Kansas to northern Arizona, New Mexico, and northern and western Texas to northern Chihuahua, Mexico. The variety rarely is cultivated, as an individual plant may go up to seven (or more) years before flowering, after which it dies.

Inclusion here of var. mogollense, characterized by spatulate leaves and woolly petiole bases, is now suggested, as both features fail to hold in some populations near Flagstaff, Arizona, the center of its distribution.
