Steve,
Splendid display. You've taken us to a higher level. Thanks.

In the leaf photo, the four at upper left are pin oak, the four at upper right scarlet oak, three at lower left black, three lower right northern red. Both the black and red oak display more shallowly lobed foliage on more shaded branches; this is also the case with pin and scarlet to a lesser degree. Here in N Ohio, black and pin oaks are fully defoliated, some red oaks still have some foliage remaining, while scarlet oaks typically have many leaves remaining and are still in good fall color. The acorn photos show, left to right: northern red, scarlet, black, and pin oaks. Note the stripes on the black oak acorn, along with the free-tipped scales on the cap. Barely visible on the scarlet oak acorn are the concentric striations at the tip. The red oak has typically shallow caps as shown in the photo, but this can be a variable trait.
