As might be expected,however, the line between fruits and fruit-vegetables cannotbe drawn with distinctness. Out of the very large number of different kinds of edil)lefruits, we can here consider as examples only a few of themore important, namely, the appl(», pear, cjuince, peach, plum,cherry, raspberry, strawberry, European grape, northern fox-grape, garden currant, nniskmelon, watermelon, orange,lemon, banana, date, fig, and pineapple (see Figs. 91-111). FRUITS 89. Fig. 94.—Peach (Primus Persica, Rose Family, Rosacece). A, floworingbranch. B, flower, cut vertically. C, diagram of flower. D, ovary,cut across to show the two layers of the wall, the outer (dotted) whichbecomes fleshy, and the inner (white) which becomes hardened as thestone or pit; and the two ovules of which only one commonlybecomes a seed. E, fruit with flesh cut in half vertically, showing therough stone or inner hardened part of the o^•ary wall. F, the stonebroken in half to show the single seed within. (LeMaout and Decaisne.)The plant is a tree; leaves smooth; flowers pink, appearing before theleaves; fruit downy. already intimated, the most .significant features of thechemical composition of fruits are (1) the presence in con-siderable amount of peculiar acids, (2) the predominanceof sugar in the dry substance, and (3) the presence of usefulsalts. These chemical characteristics are shown on the will also be
