5G BOTANY. 



tufted root; petioles 11 inches long, leaves ."•-."> parted, each segment 

 Lanceolate-cuneate and trind; involucre sessile, its Leaflets 3-5 cleft; car- 

 pels tailless, compressed, oval, and glabrous. Entire plant more or less 



densely covered with -ray hairs; flowers white. Found in America mosl 

 commonly from Canada north, but growing in Colorado on alpine summits, 

 where, according to Mr. J. ML Coulter, it has been found at an elevation of 

 13,500 feet. (102 



ANEMONE CYLINDRICA, Gray. — Willow Springs, Ariz.: rare there and 

 probably by scm< accident introduced. (247.) 



Myo8UEU8 minimus, L — Colorado: altitude, 8,000 feet and upwards; 



iin-iis much dwarfed. (1G9.) 



Ramm ii.i a AQUATILI8, L., var. stagnatilis, DC — Denver. Flowers 

 almost as large as B. Parshii, Richardson, var. trichophytttts, Chaix. Twin 

 Lakes, Colo., at 9,500 feet altitude. (113 and 115.) 



Ranunculus Flammula, L., var. reptans, Gray. — Colorado. (172 

 and 173.) 



Ranunculus iiydeocharoides, Gray. (PI. Thurb. p. 30G.) — Glabrous 

 throughout, flowering branches erect, numerous stolons branching off in all 

 directions and rooting; lower leaves heart-shaped, and entire, or nearly bo; 

 petioles 2-3' long, expanding and sheathing at the base; upper leaves 

 lanceolate; peduncles about as long as the upper leaves, from opposite the 

 axils of which they arise; sepals round, petals 3", tapering into a claw, 

 which has a conspicuous gland below a small sinus; stamens about 25 ; 

 carpels 15-20, forming a head 2-3" in diameter. Willow Springs, Ariz., 

 growing in water at a temperature of 50° Fahr. at an elevation of 7,202 

 feet A most interesting species, which I believe has not hitherto been 

 taken SO tar north. (217.) 



Ranunculus Cymbalabia, Pursh. — In Colorado grows everywhere in 

 low moist ground, evincing, however, a marked choice for alkaline soils, but 

 ,->till flourishing in the freshest of snow water: altitude, 5,000 to 10,000 feet 



From Saguache, in the San Luis Valley, we have a form with an erect, 

 stout scape, bearing three or tour flowers, having thicker and larger leaves, 

 and manifesting little or no tendency to produce stolons.
