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, writh 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,
