identical location from which Fendler obtained his plant, published by Dr. 

 Gray in PI. Fendl. p. 4, as B. tridentatus, H. B. K., and this I take to be 

 the same form as that above alluded to from San Luis Valley. In addition 

 to the difference noted by Dr. Gray in PI. Fendl., I find the beaks of the 

 achenia are in my specimens more tapering than in typical B. Cymbalaria. 

 Collected also in California, Eastern Arizona, and Utah. (Colorado. 101.) 



Ranunculus Andebsoni, Cray. — Belmont, Nev. (Plate i, vol. v, King's 

 Report.) 



Ranunculus adoneus, Cray. (Enumeration of Plants, Parry, Hall, and 

 Harbour.) — "Low, sparsely villous, becoming with age glabrous ; root fasci- 

 culately fibrous ; branching from base, with one to three leaves above, either 

 erect, simple, and one-flowered, or fleshy, decumbent, and with two or 

 more flowers ; leaves twice pedately parted, segments narrowly linear, peti- 

 oles at base with dilated scarious margins ; peduncle short ; corolla golden- 

 yellow; conspicuous petals flabelliform, twice as long as the hairy, oval 

 sepals ; scale at base adnate, small."* Usually a strictly alpine plant. My 

 specimens, however, were obtained as low as 6,000 feet above the sea-level. 



Ranunculus glabeeeimus, Hook. (Flor. Bor.-Am. tab. v.) — Leaves 

 rather lanceolate than ovate. 



Ranunculus affinis, R. Br., var. caediophyllus, Gray. B. cardi- 

 ophyllus, Hook. (Fl. Bor.-Am. tab. v.) — Colorado, at an elevation of 8,000 

 to 9,000 feet. -(121 and 170.) Willow Springs, Ariz., at 7,202 feet altitude. 

 Also collected by Dr. Loew in Western New Mexico. 



Ranunculus sceleeatus, L. — Cauline leaves, with a manifest tendency 

 to division of the lobes ; otherwise like an Eastern form. Colorado. (99, 

 110, 111, 116.) 



Ranunculus Pubshii, Richardson. — Among my specimens are a large 

 number with petals trifid and the scales distinctly three-lobed. Twin 

 Lakes, Colo , at an elevation of 9,500 feet. (117.) 



Ranunculus hypeeboeeus, Rottb., var. natans, C. A. Meyer. — Stem 

 weak, diffusely branched, glabrous, rooting from the nodes, creeping ; leaves 

 petioled, palmately 3-5-cleft, 3-5" wide, lobes ovate, obtuse, petioles 

 6-12" ; peduncles naked, 6-12", often reflexed ; sepals yellow, ovate, or 



* When, as frequently occurs, I have been obliged to quote a specific description, it is from some 

 imperfection in my own specimens.
