Balm, a tree the specific name being given because it was once supposed to be the Scriptural "Balm of Gilead" -- an opinion probably erroneous, for it does not at present grow in Gilead, either wild or in gardens, nor has it ever been satisfactorily proved that it ever did. It is a shrub or small spreading spineless tree, 10 to 12 feet high, with trifoliate leaves in fascicles of 2-6, and reddish flowers having four petals. It is found on both sides of the Red Sea, in Arabia, Abyssinia, and Nubia. It does not occur in Palestine.
