This fine tree is monoecious and deciduous and one of the few that provides genuine fall color, even if not quite up to New England standards. It is most easily identified by its leaves which while large, tend not to be as large as the authorities suggest and are rarely any larger than the leaves of California Sycamore with which they are often confused. There are several distinct differences (see the 4th photo). First, the maple leaf has a much longer petiole. Secondly, its main veins all radiate from the point where the petiole meets the leaf blade (the two lowest lobes on the Sycamore leaf have veins splitting off from the adjacent lobe). Thirdly, the underside of the maple leaf is glabrous, not tomentose. Fourthly, it is always clearly 5-lobed and the lobes are more diamond-shaped than triangular. The maple’s flowers and fruits are also quite different, the fruits being winged samaras. Lastly, the bark is dark brown and deeply fissured in mature trees.
