 surface of the ovate or somewhat heart-shaped acute leaves more or less pubes- 

 cent; ccdyx-teeth lanceolate, acute, shorter than the purplish corolla (spikes 4' - 15 'long) :

 lower spreading, 3-cleft, the middle lobe largest, either 2-lobed or entire. Sta- 

 mens 4, ascending under the upper lip, the lower pair shorter. Anthers ap- 

 proximate in pairs; the cells divergent. — Perennial herbs. (The Latin name, 

 thought to be derived from Nepete, an Etrurian city.)
