"Ulmus chumlia" Melville & Heybroek is a small deciduous tree endemic to the Himalaya from the Kashmir to central Nepal, and the provinces of Yunnan, Sichuan and Xizang (Tibet) in China. It is found in broadleaf forest on mountain slopes at elevations of between 1000 m and 3000 m.

Description

Very occasionally growing to 25 m high, it has a spreading crown of sinuous branches. The blackish-grey bark of the trunk is irregularly reticulate, and exfoliate. The wing-less branchlets bear narrow obovate-acuminate to elliptic-acuminate leaves < 10 cm long x 4 cm broad. The wind-pollinated petal-less flowers appear in spring, followed by orbicular samarae 10 mm - 12 mm in diameterFu, L., Xin, Y. & Whittemore, A. (2002). Ulmaceae, in Wu, Z. & Raven, P.

Uses

Like most elms, the tree is valued as fodder. The bark fibres are used for rope making and are also included with wool to make extra warm clothing Melville, R. & Heybroek, H. M. (1971). The Elms of the Himalaya. "Kew Bulletin" Vol. 26 (1). Royal Botanic Garden, Kew, London.] .

Cultivation

The tree is not known to be in cultivation beyond Asia. Specimens introduced to the Netherlands by Heybroek in the 1960s did not prove hardy in the north European climate.
