Quercus rubra L.

Red Oak

A widespreading deciduous tree. Bark grey and smooth. Young shoots are said to be slightly hairy and the cup to cover up to one quarter of the acorn but this is variable in SE Australian trees. Buds pointed and shortly hairy towards the tip. Leaves 10-22 cm long (but generally more than 15 cm long) with a dull upper surface and shallow lobing (less than half way to midrib), the longest lobes not as long as the width of the narrowest part of the leaf and the lobes tapering gradually to the tips and with a tapering leaf base; autumn colouring dull red to yellow. Acorns 1.5-2.5 cm long (sometimes foreshortened) with cup hairy inside, variable amount of acorn enclosed. [Q. borealis Michx.]
