On walls, dry banks, cottage roofs, and dry sandy ground, every 

 where. 



Annual. April. 



Root tapering, fibrous. Herb varying greatly in luxuriance, up- 

 right, simple or branched, hairy, light green, from 3 to 12 inches 

 high. Leaves various in shape and size, lanceolate, ovate, or 

 obovate, entire or unequally notched, their pubescence short, 

 mostly forked 3 radical ones close to the ground, numerous, 

 stalked ; the rest smaller, few, and scattered, sometimes linear- 

 lanceolate. Fl. small, white, corymbose, on slender stalks. 

 Cal. generally a little bristly in the upper part. Pet. twice as 

 long, nearly upright. Glands minute, and inconstant, curved, 

 but scarcely protruding between the calyx-leaves. Pods ascend- 

 ing, on spreading stalks, slender, somewhat curved, smooth, 

 hardly an inch long. 



Plukenet's and Petiver's figures of the variety /S are very dissimilar, 

 but specimens may be found answering to either, nor are any of 

 the varieties at all constant. The whole plant has a warm pun- 

 gent flavour, like the rest of its class. 



2. A. stricta, Bristol Rock-cress.
