sycamine tree

Sycamine tree
mentioned only in Luke 17:6. It is rendered by Luther "mulberry
tree" (q.v.), which is most probably the correct rendering. It
is found of two species, the black mulberry (Morus nigra) and
the white mulberry (Mourea), which are common in Palestine. The
silk-worm feeds on their leaves. The rearing of them is one of
the chief industries of the peasantry of Lebanon and of other
parts of the land. It is of the order of the fig-tree. Some
contend, however, that this name denotes the sycamore-fig of
Luke 19:4.
