WHITE 



CRINKLE-ROOT. TOOTHWORT. PEPPER-ROOT. 



Dentaria diphylla. Mustard Family (p. 17). 



Rootstock. Five to ten inches long, wrinkled, crisp, of a pleasant, pun- 

 gent taste. Stem. Leafless below, bearing two leaves above. Leaves. 

 Divided into three toothed leaflets. Flowers. White, in a terminal cluster. 

 Pod. Flat and lance-shaped. 



The crinkle-root has been valued not so much on account 

 of its pretty flowers which may be found in the rich May woods 

 but for its crisp edible root which has lent savor to many a 

 simple luncheon in the cool shadows of the forest. 



SPRING-CRESS. 



Cardamine rhomboidea. Mustard Family (p. 17). 



Rootstock. Slender, bearing small tubers. Stem. From a tuberous 

 base, upright, slender. Root-leaves. Round and often heart-shaped. 

 Stem-leaves. The lower rounded, the upper almost lance-shaped. Flowers. 

 White, large. Pod. Flat, lance-shaped, pointed with a slender style 

 tipped with a conspicuous stigma ; smaller than that of the crinkle-root. 



The spring-cress grows abundantly in the wet meadows and 

 about the borders of springs. Its large white flowers appear as 

 early as April, lasting until June. 



WHITLOW-GRASS. 



Draba verna. . Mustard Family (p. 17). 



Scapes. One to three inches high. Leaves. All from the root, oblong 

 or lance-shaped. Flowers. White, with two-cleft petals. Pod. Flat, vary- 

 ing from oval to oblong, lance-shaped. 



This little plant may be found flowering along the roadsides 

 and in sandy places during April and May. It has come to us 

 from Europe. 



SHEPHERD'S PURSE. 



Capsella Bursa-pastoris. Mustard Family (p. 17). 



Stem. Low, branching. Root-leaves. Clustered, incised or toothed. 

 Stem-leaves. Arrow-shaped, set close to the stem. Flowers. White, 

 small, in general structure resembling other members of the Mustard family. 

 Pod. Triangular, heart-shaped. 



This is one of the commonest of our wayside weeds, working 

 its way everywhere with such persistency and appropriating 

 other people's property so shamelessly, that it has won for itself 

 the nickname of pickpocket. Its popular title arose from the 

 shape of its little seed-pods.
