 cordate, coarsely toothed. Flowers in 

 dense axillary clusters, often slightly 

 stalked, and turned to one side, assum-

 in Stachys, usually shorter than the floral 

 leaves, and accompanied by a number of 

 stiff, linear bracts. Calyx 4 or 5 lines 

 long, green or purplish, with 10 promi- 

 nent ribs, and 5 broadly ovate teeth, 

 each terminating in a fine, stiff point. 

 Corolla purplish, with an oblong or oval, 

 concave and somewhat arched upper lip, 

 scarcely shorter than the 3-lobed, spread- 

 ing lower lip.

 ^Russian Asia. In Britain it extends
