CONTRIBUTIONS TO WESTKRN BOTANY. 715 



hairy within; anthers glabrous. This seems to differ 

 from P. Parry i chiefly in the blue flowers. 



P. acwninatus Douglas is a plant of the northwest rang- 

 ing through the Great Basin, while the plant of the plains 

 (P. Fendleri Gray) is certainly as distinct as most of the 

 reputed species. 



P. confusus Jones connects acuniinatus and Parryi and 

 may run into one or the other. P. Wrightii Gray, which 

 is the same as P. Utahensis Eastwood, seems sufficiently 

 distinct, but these with P. funiceiis form a very closely 

 related group. 



Pentstemon Eatoni var. undosus. 



No. 5iioah. April 26, 1894, in red sand at St. George, 

 Utah, 2700° alt. 



No. 5289U. May 23, 1894, Johnson, Utah, 5000° alt., 

 in red sand, among junipers. 



Scabrous or short -pubescent, except the flowers and 

 uppermost stems; lower stem leaves 3—5' long, narrowly 

 oblong, \Y wide, wavy on the margin. 



This was also collected by Capt. Bishop in the same 

 region in 1872. It grows among the junipers in gravelly 

 soil throughout northern Arizona along the Colorado 

 River and into Utah as far as the rim of the Great Basin, 



Pentstemon confertus var. aberrans. 



No. 560'ii. July 6, 1894, Soldier Summit, Utah, 

 7300" alt., in gravel. 



No. 5740. August 4, 1894, Fish Lake, Utah, 9000° 

 alt., in meadows, in gravel. 



Flowers about the size of P. hiimilis var. breviflorus or 

 a trifle larger and plants with the habit of P. humilis; i" 

 high or less, not glandular, otherwise almost exactly as 

 P. confertus. This variety abounds throughout the 

 mountains of central Utah, being more common than any 

 other form. It occurs most frequently in subalpine mead- 

 ows and shady woods in rich soil.
