2. Penstemon grandiflorus Nutt. 



Penstemon grandiflorus Nutt. in Eraser's Cat. 1813. "It was first met with 

 near the confluence of the River Platte [with the Missouri] from whence it 

 continues to the Andes [Nuttall]." Probable isotype seen in Herbarium of 

 the Academy of Natural Sciences of Philadelphia. 



Sandy prairies and open woodland, western Oklahoma, south to 

 central Texas; Lower Sonoran Zone (at altitudes of 1,500 to 2,000 

 feet). Ranges through the Plains from Wisconsin and North 

 Dakota to Wyoming and Texas. Flowering in late April and May. 



Oklahoma. Probably on False Washita, between Fort Cobb and 

 Fort Arbuckle, E. Palmer 226 (U, Y). 



Texas. Callahan: Baird (sandy woods, west of B), Reverchon 

 1342 (M). Gillespie: Sandy Creek, Jermy 280 (M). 



3. Penstemon buckleyi Pennell, sp. nov. 



Penstemon amplexicaulis Buckley, in Proc. Acad. Nat. Sci. Phila. 1861: 461. 

 1862. "About 60 miles N. E. of Camp Colorado [Texas, S. B. Buckley] 

 June [1861]." Camp Colorado, as I am informed by Mr. B. C. Tharp of 

 the University of Texas, "was in Coleman County about fifteen miles north- 

 west of the present town of Coleman." "About 60 miles northeast of" this 

 point would reach Sandy Creek in Stephens County, and it was doubtless 

 in a sand-region that Buckley found his plant. His description must be 

 modified to denote a plant with sterile filament moderately bearded [not 

 "glabro"] and with anthers glabrous [not "piloso-lanatis"]. Type seen 

 in the Herb, of the Academy of Natural Sciences of Philadelphia, and these 

 discrepancies verified and corrected. Not P. amplexicaulis Moench, Meth. 

 442. 1794. 



Corolla pale-lavender, with lavender-violet lines within on 

 anterior side. Flowering in May and early June. 



Dry sandy soil, sand-hills of western Oklahoma and northwestern 

 Texas; Lower Sonoran Zone (at altitudes of 1,700 to 2,400 feet). 

 Ranges from southwestern Kansas to Taylor, and Ward counties, 

 Texas. 



Oklahoma. Beckham: Sayre, Pennell 10553 (M, Y), 10560 

 (A, C, H, J, K, L, M, O, P, S, T, U, Y), 10565 (U, Y). Woodward: 

 Woodward, Eggert (M). 



Texas. Hemphill: Canadian, Eggert (M), E. J. Palmer 14121
