White Oak Acorns

These acorns are littering a gravel path near one of our oldest white oaks (Quercus alba). You can read more about the tree here. Note: one of the acorns is split; it has started to germinate.
These are long bullet-shaped acorns, measuring more than an inch.
These white oak acorns have a different shape. They taper much less quickly. They were collected from another old, on-site native, growing in the arboretum drainage channel on the east side of the Student Union Building. Again, one acorn has started to sprout.

We have two different white oaks, with two different acorn shapes. Both are big acorns, but one is longer and the other is fatter. Intraspecies variation on display!
