Zelkova

Zelkova is a genus of six species of deciduous trees in the elm family Ulmaceae, native to southern Europe, and southwest and eastern Asia. They vary in size from shrubs (Z. sicula) to large trees up to 35 m tall (Z. carpinifolia). The leaves are alternate, with serrated margins, and (unlike the related elms) a symmetrical base to the leaf blade. The fruit is a dry, nut-like drupe, produced singly in the leaf axils
