HOIV TO KNOW THE WILD FLOWERS 



A stamen usually consists of two parts, its Filament (F), or stalk, 

 and its Anther (A), the little sac at the tip of the filament which 

 produces the dust-like, fertilizing substance called Pollen (p). 



The Pistil (Fig. 8) is the seed-bearing organ of the flower. 

 When complete it consists of Ovary (O), Style (Sty), and 

 Stigma (Stg). 



The Ovary is the hollow portion at the base of the pistil. It 

 contains the ovules or rudimentary seeds which are quickened 

 into life by the pollen. 



The Style is the slender tapering stalk above the ovary. 



The Stigma is usually the tip of the style. The pollen-grains 

 which are deposited upon its moist roughened surface throw out

minute tubes which penetrate to the little ovules of the ovary 

 and cause them to ripen into seeds. 



A flower which has neither stamens nor pistils is described 

 as Neutral. 



A flower with only one kind of these organs is termed Uni- 

 sexual. 



A Male or Staminate flower is one with stamens but without 

 pistils. 



A Female or Pistillate flower is one with pistils but without 

 stamens. 



The Fruit of a plant is the ripened seed-vessel or seed-vessels, 

 including the parts which are intimately connected with it or 

 them.
