It also is known as cobnut or filbert nut according to species. A cob is roughly spherical to oval, about 15--25 mm (0.59--0.98 in) long and 10--15 mm (0.39--0.59 in) in diameter, with an outer fibrous husk surrounding a smooth shell. A filbert is more elongated, being about twice as long as its diameter. The nut falls out of the husk when ripe, about 7 to 8 months after pollination. The kernel of the seed is edible and used raw or roasted, or ground into a paste. The seed has a thin, dark brown skin, which sometimes is removed before cooking.
