The two kinds of fruit intergrade, depending on the state of the endocarp. The fruit is an orange size purple color berry with fleshy endocarp. The fruit is a berry with fleshy endocarp, which in several species is delicious. Pome-type fruit with stony rather than leathery endocarp may be called a polypyrenous drupe. Inside is a walnut-sized, thick-walled stone (endocarp). Stony cells are found in the endocarp of fruits such as cherries or walnuts. Germination time can also be shortened to 7 days by carefully cracking the endocarp. The innermost layer of the pericarp is the endocarp. Like other fruits, it has three layers&colon; the exocarp, mesocarp, and endocarp. Fruit is a globose, succulent drupe, with a hard endocarp; diameter ; average mass . The endocarp is the innermost layer of a fruit's pericarp. In apples, layers of elongated sclereids form the endocarp that encloses the seeds.
