 pubescent ; leaves petioled, ovate, narrowed at both ends, den- 

 ticulate or entire, rather hoary beneath; petioles ciliated; verticels 

 of the fruit bearing raceme, numerous, approximated ; calyx small, 

 a little ciliated ; corolla half longer than the calyx to double the 

 length. Very common; grows all over the world. Africa is sup- 

 posed to be its native country. Nearly allied to O basil icum, but 

 the flowers are only half the size. Syn. O americanum, Linn.

 length. This species has been long in cultivation throughout 

 Asia Hud Africa. The Indian varieties are divided into Pilosum 

 and B. glabratum. In the former, the stem is ascending, much-

 longer than the calyx ; stamens exserted. A shrub, several feet 

 high ; racemes slender, many-flowered. Syn. O zeylanicum,
