Ulmus canescens is a small deciduous tree occasionally known by the common names Grey Elm, Grey-leafed Elm, and Hoary Elm. Its natural range extends through the lands of the central and eastern Mediterranean, from southern Italy, the islands of Sicily, Malta, Crete, Rhodes and Cyprus, to Turkey, and as far south as Israel, where it is now considered rare and endangered in the wild. The tree is typically found amidst the comparatively humid coastal woodlands and scrublands.

Taxonomy
The taxonomy of the tree remains a matter of contention; some authorities, notably Richens, treated it as a subspecies of Ulmus minor.
Description
The tree is comparatively small, < 20 m high; the slender trunk, its bark coarsely fissured, supporting a rounded crown. The leaves are elliptic to ovate, bluntly toothed, and densely downy on the underside when mature, imbuing them with a distinctive greyish hue. The young shoots also have a whitish-grey down. The tree flowers in February and March, the round samarae, < 15 mm diameter, deeply notched at the outer end, ripen in April.
Pests and diseases
U. canescens is highly susceptible to Dutch elm disease.
Cultivation
U. canescens is planted as a street tree in Israel and in Jordan, especially Amman. There are no known cultivars of this taxon, nor is it known to be in commerce.
Notable trees
Mature trees occur in Jerusalem near the Damascus Gate along the Prophets Road and Antal Ben Shaddad street. In Nazareth, a line of mature trees is found along the road leading to the Basilica.
