58 BOTANY. 



oblong - , 1-2"; carpels forming a compact, globose bead, style very short or 

 wanting. 'Twin Lakes, Colo. ; altitude, 9,500 feet. (100.) 



Ranunculus macranthus, Scbeele. — Usually regarded as a mere 

 variety of JR. repens, L. ; but I am satisfied from Mr. Watson's showing that 

 it is distinct, as the greater villosity, the fewer stolons, the distinctly peti- 

 olulate leaflets, the more strictly reflexed sepals, tbe large flowers, and the 

 long beaks to the carpels all indicate. Willow Springs, Ariz. ; altitude, 

 7,202 feet. 



Ranunculus kecurvatus, Poir. — Style not conspicuously recurved, 

 but in degree of bairiness, compressed achenia, relative size of sepals and 

 petals, shape and dentition of scale, markedly corresponding with descrip- 

 tion given by T. & G Colorado. (162.) 



Caltha leptosepala, DC. — A common and characteristic plant in our 

 Colorado collection ; 8,000 to 12,000 feet above the sea. (109.) 



Trollius laxus, Salisb., var. albiflorus, Gray. — One of the most 

 conspicuous early bloomers in alpine swamps, where, when found, it is 

 quite abundant. Associated with the preceding plant. (102.) 



Aquilegia Canadensis, L. — Arizona, lava rocks south of Camp Apache. 

 Leaves smaller than our Eastern form. (268.) Western New Mexico, at 

 high altitude, depauperate specimens. Coll. Loew. (164 and 167.) Utah. 



Aquilegia Formosa, Fisch. — " Distinguishable from the last by its 

 elongated sepals nearly or quite equalling the spurs, and by its stouter 

 habit, growing only on stream banks in the mountains and flowering from 

 July to September. Nevada and Utah ; ranging from the Rocky Mount- 

 ains to Oregon and Sitka, but not found in California." — Watson. 



Aquilegia oerulea, James. — Introduced largely into cultivation, and 

 to my mind the finest plant of the Rocky Mountains. Western New Mex- 

 ico ; altitude, 6,500 feet. Loew. Colorado ; open woods ; common ; alti- 

 tude, 10,000 feet. (163.) "Near Provo City, Utah. A reduced form of 

 this species, with bright blue flowers, was collected at Kanab in Southern 

 Utah, by Mrs. E. P. Thompson, in 1872. It has also recently been found 

 in the Sierras near Mount Whitney" [Cal.]. — Watson. 



Aquilegia chrysantha, Gray (Proc. Am. Acad. 8, p. 621). A. lep- 

 tocera, Nutt., var. flava, Gray. — Usually, though not always, taller than
