Size and bearing
Up to 30 meters high, imposing appearance and dense foliage that almost reaches the ground.
Trunk and bark
The trunk is completely branched a short distance from the base; it is deeply grooved and covered with an opaque, wrinkled, greyish peeling in small irregular plates.
Deciduous, alternate, elliptical leaves, 5-9 cm lubricates, with acute apex and toothed margin.
Monoecious plant: male flowers are arranged in sessile, axillary, yellow-greenish glomeruli; the female ones are solitary, axillary, greenish. The fruit is a woody, subglobose, asymmetric, apiculate, 5-8 mm achene.
The yellowish-brown wood is similar to that of the elms, however the shortness of the trunk limits its use. It has no particular pedological needs and also adapts well to urban greenery.
