five bright green sepals of united cohesion, semi -inferior 

 to the pistil. The delicate pink corolla consists of five 

 petals of distinct cohesion and superior adnation. There 

 are usually twenty stamens inserted with the petals on the 

 throats of the calyx. The base of the calyx, however, is 

 united with the base of the pistil or ovary, which has five 

 cells, with two ovules in each cell. The pistil has five 

 styles, with a rounded stigma on the end of each. As in 

 all plants, the flower of the apple bears a definite relation 

 to the stem and branches. The flower buds and the leaf 

 buds arise in the same position. The sepals, as shown 

 by their form and color, are but modified leaves; so also 

 are the petals, though their appearance does not show it 

 so plainly. The pistils and stamens, too, are merely 

 modifications of leaves. The apple-blossoms by their fra- 

 grance attract the bees and thus, through the agency of 

 these insects, cross-fertilization takes place. 



Apple-blossoms. 



6. The fruit of the apple-tree is an indehiscerit pome. 

 It matures late in the summer and during the fall. The 

 skin is generally smooth and variously colored, being red, 

 yellow, brown, or striped, according to the variety. The 

 apple is really the matured calyx of the blossom. In the 

 center is the core, which in a cross-section appears as a 

 star-shaped figure of five points. These are the ovary 

 cells, and they contain the seeds. The seeds are brown 

 when ripe and their coats are not very hard. The kernel 

 has a rather rich taste not at all unpleasant.
