Many specimens of Penstemon from the Appalachian Piedmont combine morphological features of P. australis and P. canescens. These plants usually have equally developed cyme branches (as in P. canescens) but ascending or erect peduncles and pedicels (as in P. australis). Leaf shape generally is intermediate between P. australis and P. canescens. F.W. Pennell in the 1930s annotated most such specimens as P. australis. F.S. Crosswhite (1965e) also included these specimens in his concept of P. australis, assigning them subspecies status.... The relationship of these plants remains unclear; they will key to P. canescens or P. laxiflorus. Read more at Flora of North America.
