Variety arcuatum is widely distributed and occasionally common from southeastern Wyoming south in central and western Colorado, eastern Utah, northern Arizona, and northwest New Mexico. Some specimens of var. arcuatum gathered in southeastern Wyoming can be difficult to distinguish from Eriogonum flavum. Plants with capitate inflorescences, sometimes recognized as var. higginsii, occur throughout the range of the variety. If such distinction is to be made, the earliest available epithet is tectum.
