 etc. 



Some flowers perfect, some 

 staminate, others pistillate.

 power of self-pollination. 



Stigma matures before an- 

 thers. *

 mon. 



Anthers mature before stig- 

 mas, 2 sets of stamens ma-

 separate from staminate. 



Outer anthers mature a little 

 before stigmas, but self- 

 fertilization from the inner 

 row of anthers is common. 



Stigma a landing place for 

 incoming insects. Self-fer- 

 tilization infrequent.
