Discussion

Subspecies serpillifolia is likely native to the central-western United States and Canada, and it may be disjunct in northern Argentina. It appears to be adventive in eastern Canada and possibly other northern and eastern parts of its range. A report of the species from Cameron Parish, Louisiana, was based on a misidentified specimen of E. glyptosperma.
