Quercus canariensis

Algerian oak is in the white oak group (Quercus) in the beech or Fagaceae family, and is native to southern Portugal, Spain, Tunisia, Algeria and Morocco (not occurring in the Canary Islands as the name might suggest). It can reach about 30 m in height.

• Leaves are deciduous to semi-evergreen, and are alternate, simple, up to 10–15 cm long and 6–8 cm wide, with 6–12 pairs of shallow lobes.
• Flowers: Male catkins are 4-8 cm long; female (pistillate) flower is inconspicuous, on a short pedicel; flowering is between April and May.
• Fruit is an acorn 2.5–3.5 cm long, ovoid-cylindrical, short-stalked (0.5-1 cm), in clusters of 2–3, the cup covering 1/3 of the nut; cup is hemispherical with tomentose, lanceolate, bulging scales; fruit matures in one year.
• Bark is blackish, fissured, thick; twigs are grey green, first densely pubescent, then smooth and glabrous; bud is narrowly conical, 7 mm long, with pale brown scales covered with white hairs.
