Quercus libani - Lebanon oak
Lebanon oak, the Quercus libani, is a species of oak native to the eastern Mediterranean in western Asia, including in Lebanon, western Syria, northeastern Israel, eastern Turkey, and northern Iraq and Iran.
Description
Quercus libani is a deciduous tree growing to 8 metres (26 ft).[1] The deciduous leaf is slender, elongated and often asymmetrical, its base is round and its tip is slightly pointed. In the adult state the leaf's upper side is dark green and the under side is pale green.
The flowers are monoecious, meaning that flowers from both sexes can be found on the same tree. They are pollinated by wind. The tree produces acorns that grow to about 2 cm to 3.5 cm in diameter.[1] Its length is half covered by the cupule.
Uses
- Lebanon oak wood is very hard and resistant to insect and fungal attack and is used in construction works.
- Galls produced by the larvae of different insects that may be found on the trees have especially high tannin concentrations, are highly astringent and were used in the treatment of haemorrhage and diarrhea.
- Tannin from the galls are also used as dye.
