The stamens and petals have accomplished their work, and 
are dead. The sepals also, when colored like petals, are 
dead. But the pistil, especially the ovary, yet remains in its 
place, living and growing until the seeds which it contains 
are perfect. 
162. Thus the /ruzt is the ovary or pistils brought to per- 
fection. 
163. During the growth and ripening of the pistil, great 
and manifold changes occur, so that at last the fruit is very 
different in form, size, substance, and color. The little pistil 
in the flower of the Cherry must undergo a great alteration 
in becoming a plump Ox-heart! 
ig. 263, An umbel of Cherry blossoms,—namely, a bud, an entire flower, and a 
section showing the ove pistil and the perigynous stamens. 
Fig. 264, The drupe, cut through to show the stone and one seed, 
Fig. 265. A corymb of Strawberry,—flower and fruit. The achenia are seen on the 
surface of the fruit, which is only the overgrown torus. 
161.-Can you tell us what parts of the flower perish? What parts remain 
in place and still grow? 
162. How do you define the fruit? 
163. Mention some of the changes occurring from ovary to fruit.
