This cross between Q. macranthera and Q. frainetto was bred and grown in 1961 by Mr. Van Hooey of the Trompenburg Arboretum, Rotterdam. In its younger years it grew as a narrow spherical tree but later became more broadly spherical to almost ovoid. The leaves closely resemble those of Q. frainetto but are more obovate and remain a little smaller. The top of the leaf is somewhat more pointed. The dead leaves remain on the tree until deep into winter. The acorns are elongated, 3 - 4 cm long. The cupule is covered with contiguous scales. Despite being still young, the tree has already proved its worth as a park tree. Q. 'Macon' is also a very worthy avenue tree.
