Some sources have attempted to quantify the difference, e . g . requiring the endocarp to be less than 2 mm thick in a berry.

Stone fruits are referred to as drupe, which are fruits containing a seed encased by a hard endocarp, surrounded by a fleshy outer portion.
43.
The dry and densely textured flesh ( mesocarp ) easily separates from the stone ( endocarp ) and opens along the ventral suture at full maturity.
44.
The large fruit is round or slightly egg shaped, maturing to bright red or orange in color, with a fleshy mesocarp and a membranous endocarp.
45.
Trees are usually 10 30 m tall; trunk is usually 10 50 cm velutinous, with persistent style branches; endocarp ca . 1 mm thick.
46.
A pecan, like the fruit of all other members of the hickory genus, is not truly a nut develops from the endocarp and contains the seed.
47.
The fruit usually weighs 25g, of which 30 % is pulp, 65 % is ligneous endocarp and 5 % is seed ( bean / almond ).
48.
Differences between tree populations are expressed morphologically based on leaf length, width and area, endocarp shape, seed shape, pulp thickness and number of leaves.
49.
It contains fat, carbohydrates, protein, zinc, calcium and vitamin A . The endocarp is hard, woody, containing a large seed with abundant endosperm.
50.
They are both termed drupes because both have a hard endocarp, or pit, surrounding the seed, with the endocarp naturally splitting along a fracture line during germination.
