96 PLANTS GROWING IN MOIST SOIL. 



that borders streams and damp thickets ; and we sometimes 

 find the C. stoloiiifera also sauntering towards the swamps in its 

 desire to quench its thirst for moisture. The little flowers are 

 very similar in arrangement to those of C, Florida^ page i6o, 

 Plate LXXXI. We cannot but lament, however, that they are 

 without the petal-like involucre that is the beautiful feature of 

 the dogwood family.

This is perhaps the prettiest of our cresses. It has an agree- 

 able bitter taste which appeals to us as being particularly re- 

 freshing when we find it beside the trickling, sparkling stream 

 that it loves so well. 



CUT-LEAVED TOOTHWORT. PEPPER-ROOT. 



Denta7-ia lacitiiata. 



FAMILY COLOUR ODOUR RANGE TIME OF BLOOM 



Mustard. White or pinkish Scentless. Ne^v England south- April-June, 



purple. ward and westward. 



Flowers : growing in a terminal raceme. Calyx : of four sepals that fall 

 early. Corolla: of four cruciferous petals. Stameits : six, of which two are 

 shorter than the others. Pistil: one. /'^a'; lance-shaped. Leaves: in whorls 

 of threes ; each leaf being divided into linear, gash-toothed divisions. Stem : 

 erect; simple. Rootstock: tuberous. 



The cut-leaved toothwort is a near relative of the toothwort 

 of the rich woods. Its taste for water, however, has induced it 

 to stray from the family environment to the banks of streams. 

 Here, no doubt, it has further offended its family by putting on 

 style, or, to be explicit, by adding another leaf to its stem. And 

 those of the woods cannot cry out against it, for its rootstock is 

 quite as edible as their own.
