being a merce 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 s¢mple 
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

124. Name an important distinction in ovaries. When is the ovary or 
pistil compound?
