Penstemon sudans is closely related to P. deustus. The two were considered conspecific by Keck (1940). Keck felt that some of the Oregon Coast Range collections of P. deustus approach P. sudans in glandulosity, but these collections do not have the stout stems and densely flowered cymes characteristic of P. sudans.
