The family Fagaceae, or beech family, is characterized by alternate
leaves with pinnate venation,
flowers in the form of
catkins, and
fruit in the form of
nuts, one to seven in a scale or spiny husk that may or may not enclose the nut. The best-known group of this family is the
oaks, genus Quercus, the fruit of which is called an
acorn. The husk of the acorn in most oaks only forms a cup in which the nut sits.
