Herbs, or low shrubs, with entire or sparingly dentate leaves, and rather large flowers 

 variously clustered. Calyx tubular or oblong, mostly gibbous at the base, about 13-nerved, 

 2-lipped, naked or villous in the throat, the upper lip 3-toothed, the lower 2-cleft. Corolla 

 usually expanded at the throat, the tube straight, mostly longer than the calyx, the limb 

 2-lipped ; upper lip erect, entire or emarginate ; lower lip spreading, 3-cleft. Stamens 4, all 

 anther-bearing,' didynamous, ascending under the upper lip of the corolla, somewhat con- 

 nivent in pairs, the longer mostly exserted; anthers 2-celled, the sacs divergent or divaricate. 

 Ovary deeply 4-parted ; style glabrous, 2-cleft at the summit. Nutlets ovoid, smooth. [Greek, 

 bed-foot, the flowers likened to a bed-castor.] 



About 60 species, natives of the north temperate zone. Besides the following, 4 others occur

 ters about i' in diameter; bracts setaceous, hirsute- 

 cilia.te, usually as long as the calyx-tube; calyx pu- 

 bescent, somewhat gibbous, the setaceous teeth of 

 its lower lip rather longer than the broader ones of 

 the upper ; corolla purple, pink, or white, little ex- 

 ceeding the calyx-teeth. 



In woods and thickets, Newfoundland to North Caro- 

 lina, Tennessee, Minnesota and Manitoba, in the Rocky
