Again—in Mulberry, Fig, and Pineapple, the whole infloicscence is con-solidated into the matured fruit. THE FKUIT. 51 145. As a rule, the structure of the fruit agrees essentiallywith that of the ovary. In many cases, however, the fruit un-dergoes such changes in the course of its growth from the ovaryas to disguise its real structure. An early examination, there-fore, is always more reliable in its results than a late one. Forexample, the Oak-acorn is a fruit with but one cell and oneseed, although its ovary had three cells and six ovules ! Thissingular change is due to the non-development of five of itsovules, while the sixth grew the more rapidly, obliterated thepartitions by pressing them to the wall, and filled the wholespace itself Similar changes characterize the Chestnut, Hazel-nut, and that whole Order. The ovary ofthe Birch is 2-celled, 2-ovuled; but by thesuppression of one cell with its ovule, thefruit becomes 1-celled and
