In mountainous pastures in the north of England, among limestone 

 rocks and lead mines. 



About Settle and Malham, Yorkshire. Ra?j. At Matlock bath, 

 Derbyshire. 



Perennial. June, July. 



Root much branched at the crown, running deep into the ground, 

 but not creeping. Herb smooth and glaucous. Stems several, a 

 span high, leafy, all simple, unless eaten down early by cattle, 

 in which case they branch from the base, any small lateral shoot, 

 as in Engl. Bot., being extremely rare. Leaves scarcely, if at 

 all, toothed ; the radical ones in dense tufts, stalked, ovate or 

 obovate, obtuse, a little wavy ; those of the stem numerous, 

 sessile, arrow-shaped, mostly acute at each end. Fl. white, small, 

 but the petals vary in size, and are slightly notched. Anth. pur- 

 plish, as is likewise the calyx. Pouch obovate and obtuse, seldom 

 so much heart-shaped as in Engl. Bot., nor do its bordered lobes 

 ever reach half the length of the slender prominent style. Seeds 

 tawny, 3 or 4 in each cell. 



Tlie attentive reader will find my synonyms of this and the last, as 

 well as of Lepidium. campestre and hirtum, a little at variance 

 with those of the learned and accurate Prof. DeCandolIe ; and 

 in deference to such authority I have revised them j but this ex- 

 amination has confirmed their original application. The descrip- 

 tion and figure in Engl. Bot. will not, I think, be found to dis- 

 agree with each other j see Hooker under T. perfvUatum.
