The family Fagaceae
, or beech
family, is characterized by alternate, entire leaves
with pinnate venation, flowers
in the form of catkins[?]
, and fruit
in the form of nuts, either one or two 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 cap on the nut.
This family is closely allied with the Betulaceae, the birch family.
