FLOWERS 



flowers as those or- 

 gans or groups of 

 organs, having to do 

 with seed produc- 

 tion, which appear 

 before the seeds and 

 fromapart of which 

 the seeds develop. 

 According to this 

 definition, all 

 plants which pro- 

 duce seeds also 

 produce flowers, 

 and you may take 

 it as a rule that 

 all fruits and seeds 

 are preceded by 

 flowers. 



According to 

 the definition just 

 given, it is evident 

 that gymnosperms 

 (page 183) have 

 flowers as well
