|discussion=<p>In North America <i>Platanus</i> 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, <i>Ficus</i> sycomorus Linnaeus, its specific epithet from the Greek sykomoros, mulberry.</p>
