168 WILD FLOWER PRESERVATION 



The Stigma is variously shaped, being some- 

 times a mere point, sometimes a head, and at 

 other times lobed or divided. Examples of 

 various stigmas : (73, A to r) 



The surface of the stigma is either sticky or 

 feathery, so that it may retain the pollen grains 

 that fall upon it. (See Fertilization, p. 172.) 



The Style is the connecting tube between the 

 stigma and the ovary, and it is long or short 

 according to the requirements of individual 

 plants. (74, A and B) 



Some pistils have several styles. (75, A and 



B) 



If the style is missing the stigma is said to 

 be sessile upon the ovary. 



The Ovary is the enlarged portion at the 

 base of the pistil or carpel. It consists of one 

 or more Cells, each containing one or more 

 Ovule.s or Seed-Eggs. An Ovary (sectional 

 cutting). (76) 



The shape of the ovary is infinitely varied. 

 If there is no stigmatic surface, or if there is 

 no ovule in the ovary, such a pistil is said to 

 be imperfect, or barren.
