The perfectly symmetrical arrangement of the leaves of this plant and the star-like, bright faces that shoot out from their axils make it very noticeable. It is closely related to L. terrestris of the moist meadows; but is fond of the light soil of open woods and sometimes even appears along the roadsides. This difference of taste is probably owing to the considerate forethought of the family, which wish to put themselves as much en evidence as possible, and to be ready to assist the poor farmer by using their soothing influence upon his quarrelsome beasts.
