Mayweed or Stinking Chamomile

A 8 to 24 inch tall plant with daisy-like flower heads and an unpleasant odour when leaves crushed. Flower heads about 0.75 to 1 inch in diameter with white ray flowers surrounding a yellow, domed central disk. Leaves alternate, bright green and so dissected that they are fern-like. Stem green and smooth.
