SHEPHERD'S -PURSE 



Sfcm. — Erect, slender, smooth, or pubescent, one or 

 several rising from a rosette of spreading leaves. 



Leaves. — Basal leaves lyrate, spatu- 

 late, or oblanceolate, more or less 

 toothed, three-fourths to two inches 

 long; stem-leaves spatulate or linear, 

 one-half to one inch long. 



Flowers. — White crucifers, rather 

 large; petals much longer than the 

 calyx; pods one-half to an inch long, 

 linear, nerved. 



The Lyre-Leaved Rock-Cress ap- 

 pears on sandy hillsides in sunny 

 places. The little rosette from which 

 the stems arise is about from three 

 to four inches across and made of 

 many small, deeply cut, obovate 

 leaves. The stems vary in number 

 from one to four and bear at their 

 summit a cluster of white flowers 

 rather large for the type. The 

 raceme lengthens as the flowers ap- 

 pear, after the fashion of Cruci- 

 fercB, and a trail of slender pods 

 soon follows.
