Ulmaceae

Species of tree in the family Ulmaceae

Ulmus laciniata, commonly known as the cut-leaf elm, is a species of tree in the family Ulmaceae. It is native to northeastern Asia, including regions of China, Japan, Korea, and Russia. This species is notable for its deeply lobed leaves, which give it a distinctive appearance compared to other members of the genus Ulmus.

Description

Ulmus laciniata is a deciduous tree that can grow up to 20 meters in height. The bark is grayish-brown and becomes fissured with age. The leaves are alternate, simple, and deeply lobed, with a serrated margin. The leaf surface is rough to the touch, and the underside is paler with prominent veins.

The flowers of U. laciniata are small, greenish, and appear in clusters before the leaves emerge in spring. The fruit is a samara, which is a winged seed that aids in wind dispersal.

Distribution and habitat

This species is found in mixed forests and along riverbanks in its native range. It prefers well-drained soils and can tolerate a range of soil pH levels. Ulmus laciniata is hardy to cold temperatures, which allows it to thrive in the northern parts of its range.

Uses

Ulmus laciniata is occasionally used in landscaping for its ornamental foliage. It is also studied for its potential resistance to Dutch elm disease, a serious threat to many elm species worldwide.

Conservation

While not currently listed as threatened, Ulmus laciniata faces habitat loss in some areas due to deforestation and land development. Conservation efforts focus on preserving natural habitats and studying the species' ecological role in forest ecosystems.
