In fleshy fruits, however, there is frequently a deposition of ligneous cells in the endocarp, forming the stone of the fruit; and even in the pulpy matter of the sarcocarp, there are found isolated cells of a similar nature, as in some varieties of pear, where they cause a peculiar grittiness.

In some cases this appearance is local, occupying one end of the fruit, or making a band around the middle and contracting it like a cincture, as though its presence prevented the proper growth and development of the sarcocarp or fleshy mass of the fruit.

It would be an interesting study to trace out those plants which do furnish a well developed fleshy substance or sarcocarp, without the true seeds.

The mesocarp is generally pulpy and succulent, so as to be truly a sarcocarp, as in the peach, but it is sometimes of a tough texture, as in the almond, and at other times is more or less fibrous, as in the coco-nut.

These layers are well seen in such a fruit as the peach, plum or cherry, where they are separable one from the other; in them the epicarp forms what is commonly called the skin; the mesocarp, much developed, forms the flesh or pulp, and hence has sometimes been called sarcocarp; while the endocarp, hardened by the production of woody cells, forms the stone or putamen immediately covering the kernel or seed.
