Weeping beech measure in length. Flowers appear in the spring and are inconspicuous. The beechnuts sit in a thin spiny husk and are less than 5 cm in diameter. The triangular beech nuts are popular in autumn with birds, mice and squirrels. The green leaves become copper-toned in the fall. In winter the skeleton of the silvery stem with its branches remains attractive.

Forests of the Iberian Peninsula blackberry bushes, blackthorn, hawthorn and other more or less thorny shrubs; this role can also be filled by smaller thorny plants, "los piornales", and clumps of broom. The major forests in this area are beech, oak, birch, and fir. Beech forests ("Fagus sylvatica") are found in the mountain layer of the Iberian Eurosiberian region from 800 to 1500 metres up. The soil is cool, as often chalky as siliceous (rich in silica), and nearly always acidified by rain. The layer is characterised by the beech tree. The beech tree projects a deep shadow, and so its dense foliage usually excludes
