 leafy-bracted spikes or racemes. Calyx tubular, 13-nerved, villous in the throat, the mouth 

 mostly contracted in fruit, gibbous on the lower side at the base, or nearly terete, 2-lipped, 

 or nearly equally 5-toothed, the upper lip 3-toothed, the lower 2-cleft. Corolla-limb 2-lipped, 

 the upper lip erect, entire, emarginate or 2-lobed, the lower spreading. 3-cleft. Perfect stamens 

 2, ascending under the upper lip, their anthers 2-celled, the sacs divergent or divaricate. 

 Sterile stamens (staminodia) 2, minute, or none, very rarely anther-bearing. Ovary deeply 

 4-parted ; style 2-cleft at the summit, glabrous. Nutlets ovoid, smooth. [Greek, sweet smell.]
