First Report on the Flora of Wyoining: i6i 



Pentstemon acuminatus, Dougl. Lindl. Bot. Reg. t. 12S5 (1829). 



Abundant in the Laramie range in the foothills, on stony slopes. 

 Laramie Hills, June 7, 1894 (No. 180); Table Mountain, June 28, 

 1895 (No. 1325). 

 Pentstemon caeruleus, Nutt. Gen. ii, 52 (1818). 



Frequent on the Laramie Plains, especially on sandy ridges bor- 

 dering on the Laramie River; June 7, 1894 (No. 179); June 18, 

 1895 (No. 1308). 



Pentstemon csespitosus, Nutt. Gray, Proc. Am. Acad, vi, 66. 



A few good specimens of this rather rare plant from Wheatland, 

 June 11, 1892, by B. C. Buftum. 



Pentstemon confertus cseruleo-purpureus, Gray, Proc. Am. Acad, 

 vi. 72. 



Frequent on subalpine grassy slopes, and much reduced speci- 

 mens from alpine locations. 



Saratoga July 17, 1892; Union Pass, August 11, 1894 (No. 833); 

 Union Peak, August 13, 1894 (No. 1017). 



Pentstemon cristatus, Nutt. Gen. ii, 52 (1818). 



Common in sandy ravines in the foothills of the Laramie range 

 and probably elsewhere. 



Telephone Canon, June 15, 1894 (No. 235); Pole Creek, June 28, 

 1895 (No. 1346). 



Pentstemon glaber, Pursh, Fl. Am. Sept. 738 (1814). 

 Infrequent and usually only scattering plants. 

 Sybille, July 8, 1894 (No. 327); Cottonwood Canon, August 4, 

 1895 (No. 1566). 



Pentstemon glaber Utahensis, Watson, Bot. King Surv. 217 (1871), 

 Slightly variant, but 1 believe true specimens of this were ob- 

 tained in three localities: Gros Ventre River, August 18, 1894 

 (No. 1093); Cummins, July 30, 1895 (No. 1541); Cottonwood 

 Canon, August 4, 1895 (No. 1579). 



Pentstemon glaucus, Graham, Edinb. Phil. Journ. 1829, 348. 



Herbarium specimens fail to do justice to this singularly beautiful 

 plant, as shape and color are both largely lost. It occurs in the 

 alpine region of all our ranges. 



Tetons, August 21, 1894 (No. 1001); Laramie Peak, August 7, 

 1895 (No. 1619); La Plata Mines, August 22, 1895 (No. 1792).
