Caltha leptosepala, D. C. Syst. i, 310. 



Very abundant in wet grounds at 9,000- 10,000 ft., greedily eaten 

 by elk and locally called "Elk Slip." Union pass. August 13, 

 1894 (No. 1023). 

 Trollius laxus, Salisb. Trans. Linn. Soc. viii, 303 (1803). 



In the mountains at 9,000 ft. and upward. Union Pass, August 

 14, 1894 (No. 886); Medicine Bow Mountains, August 22, 1895 

 (No. 1709). 

 AcLuilegia cserulea, James. Long's Exped. ii, 345. 



The queen of Columbines, superbly handsome. In the woods at 

 8,000-10,000 ft. Laramie Hills, June 22, 1894 (No. 249), B. C. 

 Buffum. 



Aquilegia cserulea alpina, n. var. 



This, it seemed to me, must be A. pubescens, Coville, but Dr. 

 Robinson thinks it is rather a form of caernlea. Further examina- 

 tion convinces me that this is right. It is hardly Dr. Gray's var. albi- 

 flora,{ox these specimens are all distinctly yellow and in habitat strictly 

 alpine. The variety differs from the species in the smaller size of 

 the plant and larger leaves with upper leaflets entire; in the smaller 

 flowers and very much shorter spurs. 



Possibly confined to the Wind River Mountains, where it occu- 

 pies crevices and ledges of the naked summits above timber line. 

 Observed by Prof. B. C. Buffum, in such locations in 1892 and col- 

 lected by the writer on LTmon Peak at 10,500 ft., August 13, 1894 

 (No. 894). 

 Aquilegia Laramiensis, n. sp. 



Many stemmed from a rather large, semi-fleshy root; 6-9 inches 

 high. The stems and petioles inclined to be decumbent and dif- 

 fuse. Spurs short, hooked and knobbed. Slightly pubescent on 

 the underside of leaves, on flowers, follicles and pedicels. Sepals 

 greenish white, lanceolate with emarginate apex; lamina, of the 

 light cream-colored petals, obtuse eUiptical, longer than the spur. 



It differs from A. saxitnontana in its greater pubescence and 

 larger leaflets; from A. brevistyla in having longer petioles with 

 dilated bases; from A. flavescens in habit and especially in 

 habitat.* 



*I am indebted to Dr. Robinson for making comparison of this with the nearly related 

 species.
