A baby-acorn of red oak on a branch fallen perhaps from the middle part of the crown. Acorns of red oak are borne mostly singly
at the bottom of current-year shoots. It takes two years for the red-oak acorns to ripen. This is not unique: some oaks grow
acorns in one year, others in two. In species with a two-year growth span, such as this, fertilization takes place only after
a year upon pollination.
