2 PLANTS BAKERIAM;. 



the Old World R. sceleratus, I credited it to no station more 

 southerly than middle Colorado. The present record would 

 therefore be a considerable extension of its range. But my 

 herbarium shows that I myself collected it in 1889 as far 

 south as Trinidad, on the extreme southern verge of Colo- 

 rado. Mr. Heller has more recently distributed it from Rio 

 Arriba Co., New Mexico; and I may here note that in 1898 

 I found plenty of it along the muddy margin of a lake in 

 southern Minnesota not far from Windom, this being its 

 most easterly habitat so far as known. 



RANUNCULUS EREMOGENES, var. PILOSULUS. Much smaller 

 than the type, with several subequal ascending stems 5 or 

 6 inches high; herbage of a deeper green and sparsely 

 pilose-pubescent; receptacle, heads and achenes much as in 

 the type, but all smaller. 



In damp places above Gunnison, 17 July, n. 454. Quite 

 different, except as to height and mode of growth, from my 

 var. degener of the same species. 



RANUNCULUS PURSHII, Richardson. Fine large speci- 

 mens, growing in ponds near Gunnison, n. 669; differing 

 from the high-northern type in failing to show the very 

 narrowly dissected submersed leaves. A so-called "R Pur- 

 shii" of Mr. Baker's collecting at Fort Collins, Colo., in 1896 

 is clearly R. eremogenes. 



RANUNCULUS UNGUICULATUS, Greene, Pitt. iv. 142. Two 

 numbers of this, both from the Grand Mesa; 228, much 

 smaller than the type specimens and too young; 234 is 

 more mature, and large enough to represent the species well. 



RANUNCULUS OREOGENES. Of the size and habit of R. ellip- 

 ticus, with even larger and coarser roots, but foliage of dif-
