THE FLOWER.

Corolla, Fig. 95. This is the delicate, Fi - 95 - 



colored part of the flower, generally con- 

 sisting of several pieces called petals It 

 is situated within the calyx, and consti- 

 tutes the chief beauty of the flower. In 

 the red Rose, the corolla is red, and con- 

 sists of a great number of petals. In the 

 Morning Glory it consists of only a sin- 

 gle piece, and is of various colors, as 

 blue, red, or white. 



The Calyx and Corolla are represent- 

 ed in their natural positions with respect 

 to each other by Fig. 96. The Calyx 

 occupies the inferior arid outer portion of 

 the flower, being the part to which the 

 stem is joined, and in which the corolla 

 is placed. When the corolla consists of 

 a single piece, it is called monopctalous. 

 When the corolla is inserted, or comes 

 out below the germen, it is said to be in- 

 ferior, and when above the germen it is 

 said to be superior. 



Stamens, or Stamina, Fig. 97. The 

 stamens consist each of two parts, viz. 

 the anther, a, and the filament, b. The 

 filament merely serves to elevate the an- 

 ther, and is not an essential part of the 

 flower, being absent in many species. 

 The anther is an essential part, as it con- 

 tains the pollen, or dust, without the influ- 

 ence of which, the species are not perpetuated, or in other 

 words the seeds will not grow. When the filaments are 

 wanting, the anthers are situated on the germen, or are at- 

 tached to some other part of the flower, as the corolla.
