O.v Some North Americax Ranunculi. 



E. ACRiFORMis, Gray, Proc. Am. Acad. xxi. 374 (1886). 

 Stems one or several, from a cluster of coarse fibrous roots, 

 a foot and a half high, strictly erect : leaves long-stalked, 

 erect or ascending ; the short-stalked leaflets divided into loug 

 linear callous-tipped segments and lobes, faintly canesceut 

 with a light appressed silky pubescence : flowers and fruit 

 much as in R. acris. 



Earely collected, this fine species abounds in damp 

 meadow lands along rivers and brooks from the high plains 

 of Wyoming northward and Avestward in the cold elevated 

 districts.^ Late in July last year I obtained it at Laramie in 

 good fruit ; the flowering season for it being nearly past at 

 that time. 



R. EEPENS, Linn. Sp. PI. 554. This, not hitherto known 

 on the Pacific Coast, has been sent me from Humboldt 

 County, California, by Mr. C. C. Marshall, Avho finds it 

 abundant about a certain pond near Areata. Not having 

 found any trace of it except in the single locality, he infers 

 that it may be an introduced plant ; which is very likely. 



R. EUGULOsus. Perennial, slender, apparently weak and 

 decumbent or reclining, 1^ to 3 feet high, nearly glabrous : 

 leaves pinnately about 5-parted or -divided, the divisions 

 cleft or divided into long linear or lanceolate seirments : 



sepals reflexed : petals 7 to 11, spatulate-oblong, * inch long : 



head of achenes slightly depressed-globose : achenes rather 



few, barely a line long including the short recurved style, 

 the sides faintly rugose-reticulate. 



The type of this new species is a very slender but tall 

 plant from the Chowchilla Mountains in the eastern part of
