It takes its name from holm, an ancient name for holly. The spanish name is ''encina'' and the catalan name is ''carrasca'' or ''alzina''. It is a medium-size tree 20-27 m tall with finely square-fissured blackish bark and leathery evergreen leaves. The old leaves fall 1–2 years after new leaves emerge. The leaves are dark green above and pale whitish-grey with dense short hairs below. An estimated half-life of Spanish oak stands at present around 400 years. The flowers arecatkins, produced in the spring; the fruit is an acorn, which matures in about sixmonths.
