Discussion
In California, Penstemon californicus is known from the San Jacinto Mountains in Orange and Riverside counties; it also occurs in the Sierra San Pedro Mártir in Baja California. The chromosome number of 2n = 16 reported by N. H. Holmgren (1993) is likely an error based on a count for Scrophularia californica reported in P. H. Raven et al. (1965) and later misattributed to P. californicus by D. V. Clark (1971) as n = 48 (the count listed in Raven et al.), and then corrected to 2n = 16.
