Evergreen oak in blossom in spring, with new, soft leaves of greyish shade, opposite to the old, deep green, hard leaves. The picture on top displays the tassels, which are masculine inflorescences delivering pollen to be disseminated by the wind. The picture below displays the minute female flower in the axilla of one leaf. Once pollinized, she'll madurate to be one acorn. [photos Florenci Vallès]
