turbinate, nearly equal, with a truncate mouth, and 5 teeth,

Whorls 6-15-flowered, distant. Corolla villous outside, pale

and tonic, with no very pleasant, but pungent smell. It was 
formerly used in Cardialgia, whence its old name; but it has 
now become wholly obsolete, except, perhaps, among cow- 
leeches and farriers. Bees are fond of the flowers. In Ger- 
man, Motherwort is called Herzgeshaun or Herzkraut. In
