n.
Any of several distinct trees called by the same name though in different genera and families.
In the U.S. the term refers to the American plane tree or buttonwood ( Platanus occidentalis ), a hardy street tree. The sycamore maple , or mock plane ( Acer pseudoplatanus ), is sometimes also called simply sycamore. The biblical sycamore, actually the sycamore fig ( Ficus sycomorus ), was used by the ancient Egyptians to make mummy cases.
