Discussion
A disjunct population of Penstemon strictus in Mono County, California, appears to be an introduction, and collections from some counties in east-central Colorado (Arapahoe) and northeastern New Mexico (Harding and Union) also probably are due to recent introductions. Penstemon strictus is a popular ornamental; it has been seeded along some highways in Arizona, Colorado, and Wyoming.
