Ulmus chumlia
''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. Richens noted that the species appeared to be the same as that named by Grudzinskaya as ''Ulmus androssowii'' var. ''virgata'', which she considered an intermediate between ''U. minor'' and ''U. pumila''. 〔Richens, R. H. (1977). Variation, cytogenics, and breeding of the European field elms. ''Annales Forestales Analiza Sumartsvo (Zagreb).'' 7, 107–141.〕
==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 apetalous flowers appear in spring, followed by orbicular samarae 10-12 mm in diameter.〔Fu, L., Xin, Y. & Whittemore, A. (2002). Ulmaceae, in Wu, Z. & Raven, P.
