The more common name for the tree is a sycamore fig, sycomore fig, or a fig mulberry. The trees do produce fruits, like other figs, but they tend to be small. Yet they are still edible and the tree is cultivated for its fruit. The sycamore fig is mentioned in I Chronicles 27:28; Psalm 78:47; Amos 7:14; and Luke 19:4. The Hebrew name for the tree is shaqam and its Greek name is sukomoraia. In England, a sycamore is a type of maple tree (acer pseudoplatanus).
