being a mere stalk, like the filament 'of a stamen or 

 the petiole of a leaf, may, like them also, be wanting, 

 without loss to the pistil. In this case the stigma is 

 sessile (sitting) upon the. ovary, as in the pistils of 

 Anemone (Fig. 207), and of Trillium (Fig. 206).

123. The ovary is a kind of sac or case, enclosing the 

 ovules (see Fig. 215, where there is but one, or in Fig. 209, 

 where there are five, and Fig. 202, where there are many 

 ovaries.) When full grown, the ovary becomes the fruit, and 

 the ovules the seeds. 



124. It is very important to distinguish between the simple 

 and the compound pistil, for when there are several in the 

 same flower they often grow together, forming a single body 

 with members more or less distinct. As the petals grow
