rent lines. The author could have added another striking differ- 

 ence in the basal leaves, but these were probably unknown, as 

 they are most commonly lacking in herbarium specimens. In 

 C. rotundifolia the basal leaves are small, thick, crenate-dentate 

 and with shallow basal sinuses. In C. intercedens they are 

 usually large, thin, with large sharp teeth and deep rounded basal 

 sinuses. C. intercedens inhabits usually rocky places, while the 

 European C. rotundifolia is a meadow plant. While the former 

 is the common plant of the eastern states and Witasek does not 

 cite a single specimen of C. rotundifolia from that region, there 

 are some specimens indicating the existence of the latter in the 

 East, probably as an introduced plant. In the Columbia Univer- 

 sity herbarium there is one from Canaan, Conn., collected by W. 

 H. Leggett, which I must refer to C. rotundifolia, and another 

 from Milford, Pa., by Dr. Britton, which, also, probably belongs 

 with it. 



Campamda petiolata DC. is the common plant of the Rocky 

 Mountain region. It is nearer the European C. rotundifolia than 

 the preceding, and if hairy on the stem at all, the hairiness is not 

 confined to lines, but extends all around. It is a stricter plant 

 than C. rotundifolia, with thicker leaves, of which the uppermost 

 are almost erect and the lower blunt, of a lighter hue and with 

 more unequal calyx lobes. The basal leaves are more inclined 

 to be ovate, rather than round-cordate. 



The range of Campamda rotundifolia in America, Witasek limits 

 to Mexico and New Mexico, with the addition of one locality in 

 Colorado and one in Idaho. It is strange if C. rotundifolia, a 

 native of the wet meadows of northern Europe and Asia and the 

 mountains of South Europe, should here be limited to the Tex- 

 ano-Mexican region. The few New Mexican and Mexican speci- 

 mens that I have at hand, I admit, resemble much the European 

 plant in general habit and hairiness, but it is taller, more slender 

 and strict. In all, the basal leaves are lacking. Maybe they 

 would furnish good characters to distingush the Texano-Mexican 

 plant. In the herbarium of the New York Botanical Garden 

 there is a duplicate of the number cited from Idaho, viz., Sand- 

 berg, MacDougal & Heller, Jjy. This is nothing but C. petio-
