بلوط متساقط الأوراق
Also known as the “deciduous oak”, the valonia oak is the national tree of Jordan. It is a woody tree with strong branches, serrated leaves, and small flowers clustered in separate male and female drooping spikes. Female flowers are pollinated by wind. They produce large acorns 4–6 cm long with cups covered by long, leathery strips.
Woodlands of the Northern Highlands, including Irbid, Ajloun, Jerash, Salt, and Wadi al-Seer.
Spring. Sheds its leaves every autumn.
Seeds are edible when leached or cooked. Bark damaged by the wasp Cynips calicos produces galls (see Plant Gall). Acorn cups and galls are used to make black ink.
