Penstemon franklinii
Penstemon franklinii belongs to Section Cristati, a group of closely allied species. This species has as its nearest ally, both morphologically and geographically, the pinyon penstemon, P. pinorum, a plant from nearby to the south in Iron County. Similar occurrences of nearly associated geographical elements are to be found in P. concinnus Keck, P. nanus Keck, and P. dolius, all of which occur in west desert valleys of Utah. Each of those differ in about the same manner and degree from each other as P. franklinii does from P. pinorum. The species is named after M.A. (Ben) Franklin, co-discoverer of the species and co-collector of the type specimen.
