Zelkova carpinifolia, known as Caucasian zelkova, Caucasian elm or just zelkova, is a species of Zelkova, native to the Caucasus, Kaçkar, and Alborz mountains in the extreme southeast of Europe and southwest Asia.
It is a medium-sized to large deciduous tree growing to 20–35 m (66–115 ft) tall, with a trunk of up to 2 m (6 ft 7 in) in diameter. The crown is a highly distinctive vase-shape, with a short broad trunk dividing low down into numerous nearly erect branches. The leaves are alternate, 4–10 cm (1.6–3.9 in) long and 2.5–6 cm (1–2+3⁄8 in) broad, the margin bluntly serrated with 7–12 teeth on each side. The flowers are inconspicuous and greenish, with no petals, and are wind-pollinated. The fruit is a small nutlet 5–6 mm (3⁄16–1⁄4 in) in diameter.
It is grown as an ornamental tree in Europe (huge exemplars of it can be found quite often in the western Georgian province of Imereti, used for decorating courtyards in villages and providing pleasant shade) and more rarely in North America (where the related Japanese Z. serrata is more popular).
