Family: Composite or Aster Family (Compostiae)
General Description: Perennial, reproducing by seed and by underground rhizomes. It is distinguished by its dark green, smooth, somewhat fleshy, dissected or coarsely toothed leaves, its large, conspicuous, daisy-like flower heads with white rays and yellow centres and its rhizomatous and fibrous-rooted underground system. When crushed, all parts of the plant have a disagreeably sour odour.
