In fruit-trees, the stamens and pistils are in the sameflower, but these two sets of organs often mature at differenttimes. Crossing is mostly effected by insects, which, becom-ing thickly dusted with powder from one flower, plunge intothe recesses of another, and effect a cross-pollination. Wheremany varieties grow in one garden, in close proximity, casesof promiscuous intermixture are constantly occurring. Thecrosses thus produced are shown usually only by raising fruitfrom the seedlings. In the annexed figure of the pear-blossom (Fig. i6), the five.
