Text-book of structural and physiological botany . he stigma is to serve for the detentionof the pollen-grains j and it is therefore universally present, 144 Strttcttiral and Physiological Botany. though it varies greatly in form.

The interior of the ovary is occupied byone or more cavities or loculi. Thus the ovaryof Leguminosae and Primulaceae is unilocular(Figs. 296, 298) ; that of Scrophulariaceaeand most Cruciferae bilocular (Fig. 297) ;that of the apple quinquelocular^ &c. Within the loculi of the ovary are \\i^ ovules^the bodies which ultimately develope into theseeds. They are fixed to certain parts of thewall of the ovary termed the placentcE.; and are either sessile(Fig. 298), or are attached to the end of a stalk ox funiculus.
