Flowers
Male and female flowers appear on the same tree, but separately, as the leaves start to unfold. Male flowers appear as drooping clusters (catkins) and females in clusters of 1 to 4. Acorns are either single or born in pairs, are oval, and up to 3/4 inch long.

A few Oak facts ..

The quote above states the flowers of Black Oak are in drooping clusters, both male and female but "females in clusters of 1 to 4". The tree in question has single catkins, what is the possibility they are all female in single 'clusters'?

Shumard oak ..

Shumard Oak, a monoecious species like all other Oaks, has pendulous pollen-bearing male catkins in mid-spring that fertilize the miniature female flowers on the same tree or on nearby trees.
