 the termination of the axis. It consists of three parts, the ovary, 

 or germ, a, (Fig. 4.) the style, b, and the stigma, c. The style is 

 sometimes wanting, and the stigma then becomes sessile upon 

 the ovaiy. (See also Figs. 10, 11.) 



76. The ovAKY (Lat. ovarium, a depositor}^ from ovum, an 

 egg) is the tumid and hollow part of the pistil, situated at its 

 base, containing the ovules, or young seeds withui its cavities, 

 aoid destined to become the fruit. 



77. The ovaiy is either simple or compound. "When com- 

 pound, it consists of two or more lobes or divisions, called 

 CARPELS {naqnog, fruit), united together more or less closely.
