Dutchman's-breeches, the slender rootstocks bear a number of 

 little spherical tubers. The common bleeding-heart of flower- 

 gardens is a relative of these two native species. 



Fumitories. The fumitories, with yellowish or pinkish, two- 

 sided flowers, occur in Minnesota in four different forms. Among 

 the more common is the pale fumitory with whitish-green leaves 

 compounded on the plan of three. This plant is most abun- 

 dant in the northern part of the state, where it grows often on 

 sandy beaches. The golden fumitory, frequent in the southern 

 part of the state along railway embankments and in woods, is 

 a smaller, darker green plant, with golden yellow flowers ar- 



ranged in terminal ra- 

 cemes. Another variety, 

 the yellow, not so com-

 tory, may be recognized 

 by its paler leaves, like 

 those of the pink-flow- 

 ered northern form; but 

 this species has yellowish 

 flowers, not so bright as 

 those of the golden fumi- 

 tory, and quite different 

 from the pinkish type of 

 the pale fumitory. Still

smaller flowers than the others and foliage much like that of 

 the pink species. 



Mustards. The mustard family is distinguished, for the mos 

 part, by a pungent peppery sap, so that after one has tasted 

 water-cress or pepper-grass he can usually determine, by c 

 ing the foliage, the relationship of other plants of the fam 

 A variety of mustards occur in Minnesota, about fifty spe 

 in all. Besides this, several are cultivated, such as the cabl 

 the cauliflower, the radish and the turnip. Mustards are : 

 ognized botanically by their pods, flattened lengthwise or en 

 wise to the partition which runs along them. In some po
