Quercus ithaburensis Quercus ithaburensis

A rare semi-evergreen tree with a crown that starts off oval and is later broad oval. The old bark is dark greyish-brown and has remarkably deep grooves. The dull green leaves are sometimes elongated but can also be oval or practically round. They are usually heart-shaped at the base, giving them a characteristic violin-like shape. They are 6 - 12 cm long and the edge has a few pointed serrations. The acorns are remarkably large, approx. 4 cm in size. They are elliptical to oval and half (or even a little more) enclosed by the cupule: the latter is densely covered with remarkably woody, backward-bending scales. This distinguishes this species from the equally little known Q. macrolepsis that has much softer and hairier scales on the cupule. Q. ithaburensis could be used more frequently because of its remarkable leaves and fruit.
