|discussion=<p>In North America Platanus is usually called sycamore, a name apparently borrowed from the European sycamore maple, Acer pseudoplatanus Linnaeus, which has similar leaves. That name in turn comes from the Middle Eastern sycomore fig, Ficus sycomorus Linnaeus, its specific epithet from the Greek sykomoros, mulberry.</p>
