In dry gravelly or chalky situations, amongst rubbish and ruins. 



Perennial. May. 



Root tapering, strong, whitish. Whole herb rough with minute, 

 close, callous bristles. Stem annual, near 2 feet high, branched, 

 round, leafy. Leaves ovate or lanceolate, greyish green, nume- 

 rous, sessile, alternate ; paler and softer beneath. Clusters axil- 

 lary and terminal, leafy, revolute, dense, finally elongated into 

 straight, leafy branches, their leaves often broader than those on 

 the main stem. Cor. of a pale buff-colour, with a protuberance 

 at the base of eacli segment. Stam. minute, in the middle of 

 the tube. Seeds grey, with a kind of porcelain polish, and a 

 stony hardness, whence they have been falsely reported to con- 

 tain calcareous earth, effervescing with acids, and to cure the 

 stone, I know not how. There are seldom more than 2 seeds 

 perfected in each flower.

 decumbent. Leaves of a brighter green, and rather more hairy, 

 than in the former, without transverse veins or ribs. Spikes ter- 

 minal, leafy, at length much elongated. Cor. white, with swell- 

 ings at the base of the limb. Seeds brown, polished, curiously
