Q. faginea - Portuguese Oak - אלון אשורי

Gall ( Quercus faginea ) Lam. Monoecious plant with showy flowers are not pollinated by the wind. Fruit in Acorn. Tree species belonging to the family Fagaceae, distributed by the western Mediterranean. Appears in the hills in a very sporadic and limited, on the slopes facing north (a Septentrion) drop of the moor, over the masses of kermes and holm oak (Wolf Canyon) and among the pine reforestation of Pinus halepensis Mill (Cerro del Viso), on more or less developed soils (loamy character, margo-gypsiferous and calcareous) and along the Paramo, also accompanying masses of kermes and holm oak (this species reached a remarkable development in the hills near the Humosa Saints, where you will find fresh and deep soil). Usually, the gall is installed on soils highly developed, deep and fresh (wet), so it is situated in a very timely in the area of study. The rare presence of gall in the hills of Alcalá, is due no doubt to the historical use that has made humans such vegetation, the lack of depth of soil is due largely to the intensity of deforestation activities and agricultural character has been suffering the territory historically, what has caused an intense washing of the soil by the action of rainfall and stormwater runoff. The gall is a tree with leaves less consistent and slightly higher than those of the oak, with a hairy back, and limbs of jagged edge. Are very characteristic galls (cancerous tissue that the plant produces in leaves, stems or shoots), where larval development occurs in a highly specific insect with the plant. It is known as the oaks marcescent ie: the leaves wither and die in autumn, but not usually detached from the tree until it is pulled and replaced by new spring leaves. It is therefore common to see blade (green / living or brown / dry) throughout the year.
