the calyx teeth of last year's flowers. A sure protection they give 

 the enclosed nutlets from seed-eating bird and inquisitive human, 

 until the old stem is ready to fall to earth. Then the nutlets are 

 loosened and soon up from them new plants spring; the old winter 

 one having been to them a literal "mother- wort." Remedies: cul- 

 tivation ; repeated cutting with hoe or spud and salting.
