erect, but are more usually ascending or decumbent ; flowers larger than in li. 

 affinis, sijiall forms of which it approaches, but from which it is easily distin- 

 guished. Rocky Mountains of Colorado and British America to Alaska. It is 

 80 Parry, 14 Hall & Harbour, and 17 Vasey. Found on the East Hum- 

 boldt and Clover Mountains, Nevada, and on the Uintas, at an elevation of

Ranunculus eepens, L. From Canada and the Atlantic States to the 

 Pa,cific. Found in the valleys of Northeastern Nevada, and the canons of the 

 Wahsatch Mountains ; altitude, 6,000 feet ; usually with small flowers and

Ranunculus maceanthus, Scheele. Linncea, 21. 586. Root fascicled; 

 stem erect, more or less hirsute with spreading hairs ; branches short, erect, 

 few-flowered ; leaves ternately, or, more frequently, bi-ternately divided ; 

 segments usually petiolulate, laciniately lobed and toothed ; flowers large, 

 with the sepals strictly reflexed ; carpels (li" long) crowded in subglobose 

 heads, about equaling the broad subulate beaks. — This is R. repens, Var. 

 macranthus, Gray, but it seems sufficiently well marked to retain its place as 

 a distinct species by its stout erect habit, uniformly large flowers with re- 

 flexed sepals, and especially by the long diverging beaks of the carpels.
