This is an extremely common and variable plant in its S'ze, the 

 shape of the leaves, and more ov less hairiness ol the plant, and it is 

 erect or rooting from the creeping stem, vaiielies seeming, as is com- 

 monly the case, to depend upon the place of gvowih being move ov less 

 wCi. It is very acrid, speedily producing inflammaiiou and blisters on 

 the skin, and its infusion is a violent emetic; but it does not appear 

 to have been applied to any useful purpose.
