 2-10 cm. long; calyx-teeth subulate, the longest one-half as long as the tube;

 at the throat, the tube longer than the calyx; the upper lip 

 arched, narrowed at the base; the middle lobe of the spreading 

 lower lip broad, notched at the apex, contracted at the base; the

 pubescent; stems simple, erect, 15-20 cm. high; lower leaves orbicular, coarsely 

 crenate, truncate or cordate at base, 1-2 cm. long, on petioles as long or longer; 

 upper sessile, half -clasping, rather distant; flowers sessile, in axillary and ter- 

 minal clusters; calyx pubescent, the sharp teeth nearly as long as the tube; 

 corolla purple, the lower lip spotted, 12-15 mm. long. Sparingly introduced 

 in cultivated ground. 



324. STACHYS. 



Herbs, rarely woody, not aromatic; calyx tubular-bell-shaped, 

 5-10-nerved, equally 5-toothed or the upper teeth united to form 

 an upper lip; corolla not dilated at the throat, 2-lipped, the tube 

 about equalling the calyx; the upper lip concave, often arched, 

 erect or rather spreading, entire or nearly so; the lower usually 

 longer and spreading, 3-lobed, the middle lobe largest and nearly 

 entire; stamens 4, ascending under the upper lip, the lower pair
