A large (and rather ill-constructed) genus, chiefly from the Old World, consisting 
of shrubs, half-shrubs, herbaceous perennials and annuals. Leaves alternate, various- 
ly divided. Heads solitary or corymbose. The garden herb Tansy is the type of 
the genus, but belongs to a section with 5-toothed corollas. Name said to bea 
corruption of A thanasia.
