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

 or genn, a, (Fig. 4.) the style, b, and the stigma, c. Tlie style is 

 sometimes wanting, and the stigma then becomes sessile upon 

 the ovar}^ (See also Figs. 10, 11.)

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

 base, contaming the ovules, or young seeds within its cavities, 

 and destined to become the fruit.

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

 CARPELS {ituqnoc, fruit), uuitcd together more or less closely.
