 Winter Cress. Petiv. H. Brit. t.46.f.l. 



Common in rather moist waste ground, about hedges, or in marshy 

 meadows. 



Perennial. May — August. 



Root tapering, somewhat woody. Stem about 2 feet high, simple 

 or branched, leafy, stout, angular and furrowed. Radical and 

 lower stem-leaves lyratej upper ones becoming gradually less 

 divided, clasping the stem ; the uppermost of all obovate, and 

 much diminished ; all are variously toothed, strongly ribbed, of 

 a firm texture, quite smooth. Fl. bright yellow, in round-head- 

 ed, corymbose clusters. Pod not very acutely quadrangular, 

 about an inch long, crowned by the thick, rather elongated, 

 style. 



The whole herb is nauseously bitter, and in some degree mucila- 

 ginous. Haller reports, after Kalm, that it is eaten in England 

 as a salad. The latter probably confounded it with the follow- 

 ing. A double-flowered variety, with innumerable petals, pro- 

 duced in long succession, and turning white as they fade, is fre- 

 quent in gardens.
