The acorn is the nut of the oaks and their close relatives (genera Quercus, Notholithocarpus and Lithocarpus, in the family Fagaceae).
Acorns have bowl-shaped caps that cover one third of the nut. Acorns usually mature in autumn. The quantity of acorns produced can vary year to year, producing about 32,000 acorns one year and very few the next. Germination of acorns is highly correlated with the amount of moisture during the rainy season. [7]
The acorn contributes to the overcup oak's common name. The acorns are almost entirely covered by their cup, hence the name overcup. [3] The cup has gray, pubescent scales. The acorns also have a unique spongy shell that make them buoyant. [8] The pericarp of overcup oak acorns is unusually large for oaks and makes up 50% of acorn mass.
