This is the rendering of the Hebrew word libneh , which occurs in (Genesis 30:37) and Hose 4:13
Several authorities are in favor of the rendering of the Authorized Version and think that "white poplar" (Populus alba ) is the tree denoted: others understand the "storax tree" (Styrax officinale , Linn.). Both poplars and storax or styrax trees are common in Palestine, and either would suit the passages where the Hebrew term occurs. Storax is mentioned in Ecclus. 24:15, together with other aromatic substances. The Styrax officinale is a shrub from nine to twelve feet high, with ovate leaves, which are white underneath; the flowers are in racemes, and are white or cream-colored.
