ASTERACEAE 
      (COMPOSITAE) 
       Sunflower Family 
      (Thistle Family)

Herbs, shrubs and even trees are in the Sunflower Family.  What seems to be a single flower is really a group of many flowers of two kinds.  The strap-shaped forms on the outer edge that look like petals are each a complete flower and are called ray florets.  The tightly packed tubular forms in the center are also complete flowers and are known as disk florets.  Some members of the Sunflower Family have only ray flowers.  Dandelions and chicory are examples.  Other members of the family have only disk florets.  Thistles are an example of this.  Ray and disk flowers are connected to a structure called the receptacle and underneath the receptacle are a number of bracts known as the involucre.  (Dale 50).  The largest family of vascular plants, with possibly 950 genera and 20,000 species, chiefly herbaceous and world-wide in distribution. (Munz, Flora So. Calif. 95).
