6. BRUNELLA L. Self Heal. 



Low perennials, the nearly simple stems terminated by a_ short- 

 spicate or subcapitate inflorescence, each whorl composed of six sub- 

 sessile flowers and subtended by broad floral bracts. Calyx reticulate- 

 veiny, membranaceous or ohartaceous, bilabiate; upper lip truncate 

 with 3 cusps; lower 2-cleft; lips closed in fruit. Corolla-throat 

 inflated and tube more or less exserted; upper lip erect, galeate, 

 entire; lower lip 3-lobed, the middle lobe hanging downward. 

 Stamens i, in pairs under the upper lip, each filament or those of the 

 upper with a small tooth below the anthers. Nutlets smooth and

 affection of the throat, which Self Heal was used to cure.)
