THE AMERICAN BOTANIST 141 



prairie was also an abundance of the yellow heads of groundsel 

 {Senecio plattcnsis). The tall vvand-likc racemes of tansy- 

 mustard {Sophia intermedia) waved in the wind beside the 

 track or in the fields. Still more slender, rose the stems of 

 the fi^wort {Scrophularia leporrlla) , small patches of which 

 appeared at frequent intervals, just coming to flowering. 

 Patches of the beautiful white flowers of the Canada anemone 

 {Anemone canadensis) which here had just come into full 

 flowering were common especially in the lower ground. 

 They remained common to Fremont, Nebraska, after which 

 none were seen. The writer recalls only one or two places 

 where he had found them near Manhattan, Kansas, in 

 earlier years. 



Most of the way was across level or gently rolling 

 prairie. On somewhat lower prairie before traveling far in 

 Minnesota the groundsel was replaced bv other vellows — star 

 grass {Hypoxis hirsuta) dotting the ground, and hawksbeard 

 {Crepis runcinata), resembling the groundsel but w^ith fewer 

 heads on more slender stems. The white flowers of camas 

 {Zygadcnus clegans) were just appearing on their tall slender 

 stalks. 



A decided change of scenery came at Granite Falls in 

 crossing the valley of the Minnesota River. Here were seen 

 outcroppings of the quartzite and in places the \allev looked 

 as if some giant steam shovel in ages past had dropped 

 masses of it here and there. Actually these are projections 

 unconquered by the glacier, the intervening spaces being 

 covered with soil. The flowers of yellow sweet clover {Mcli- 

 lotus officinalis) were first observed here. In [)laces the 

 beautiful pink jjcardtongue {Pentstcmon yrandifiorus) was 

 seen. On the barren rocky hillsides were the small white 

 beardtongue {P. alhidus) and the small primrose {Mericrlix
