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. 1 01.) 

 Ranunculus Andersoni, Gray. — Belmont, Nev. (Plate i, vol. v, King's 

 Report.) 



Ranunculus adoneus, Gray. (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 glaberrimus, Hook. (Flor. Bor.-Am. tab. v.) — Leaves 

 rather lanceolate than ovate. 



Ranunculus affinis, R. Br, var. cardiophyllus, 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 sceleratus, L.— Cauline leaves, with a manifest tendency 

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

 110, 111, 116.) 



Ranunculus Purshii, 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 hyperboreus, 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"; pedunc les naked, 6-12", often reflexed ; sepals yellow, ovate, or 



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

 imperfection in my own specimens.
