Bdellium
Occurs only in Gen. 2:12, where it designates a product of the land of Havilah; and in Num. 11:7, where the manna is likened to it in colour. It was probably an aromatic gum like balsam which exuded from a particular tree (Borassus flabelliformis) still found in Arabia, Media, and India. It bears a resemblance in colour to myrrh. Others think the word denotes "pearls," or some precious stone.

Pine tree
Heb. tidhar, mentioned along with the fir-tree in Isa. 41:19; 60:13. This is probably the cypress; or it may be the stone-pine, which is common on the northern slopes of Lebanon. Some suppose that the elm, others that the oak, or holm, or ilex, is meant by the Hebrew word. In Neh. 8:15 the Revised Version has "wild olive" instead of "pine." (See [490]FIR.)

Plane tree
Heb. armon (Gen. 30:37; Ezek. 31:8), rendered "chesnut" in the Authorized Version, but correctly "plane tree" in the Revised Version and the LXX. This tree is frequently found in Palestine, both on the coast and in the north. It usually sheds its outer bark, and hence its Hebrew name, which means "naked." (See [497]CHESTNUT.)

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.
