 mounted by the distinct upper ends of the filaments bearing 

 kidney-shaped anthers. The eight or more carpels are

Adhesion or Adnation of the Floral Organs. In 



the flowers of endogens, which usually have their parts in 

 threes, the calyx and corolla are often made up of leaves 



*This cowslip oenothera (pronounced, e-no-the'-ra the th soft) is common 

 near the coast. A smaller species is found in the interior. Children in picking 

 these flowers usually leave the ovary underground. If the class is studying in 

 September or October, rose-colored godetias (gode'tia) or Zauschneria (Fig. 59) 

 may be found. Squash or melon flowers both staminate and pistillate are 

 desirable.
