Perennial. Stem erect, ascending or decumbent, often branching at the base, 8-12 inches 

 high ; the upper part pubescent. Leaves dull green, variable in breadth ; the nerves and 

 petioles a little hairy. Spikes ovate or oblong-cylindrical, thick, terminal. Bracts mostly 

 reniform, with a short abrupt point, ciliate, often purplish. Calyx large, closed in fruit ; the 

 upper lip broad, with 3 short points : teeth of the lower lip lanceolate, pointed. Corolla violet, 

 sometimes pale : middle lobe of the lower lip finely toothed. Anthers approximated by pairs 

 beneath the upper lip.

 into many species by some European botanists. Jt seems to be an introduced plant in the 

 United States, but it has been found in nearly all parts of the world.
