| Origin | C. Asia |
The elm cultivar UlmusDensa was described from specimens growing near Ashkabad as U. densaLitv. in Schedae ad Herbarium Florae Rossicae (1908). [1] Litvinov, reporting it growing wild in the mountains of Turkestan, Ferghana, and Aksu, as well as in cultivation, considered it a species, a view upheld by the Soviet publications Trees and Shrubs in the USSR (1951) [2] and Flora of Armenia (1962), [3] and by some current plant lists. [4] [5] [note 1] Other authorities take it to be a form of U minor, distinctive only in its dense crown and upright branching. [6] [7] [8] The Moscow State University herbarium gives (2020) Ulmus minor as the "accepted name" of U. densaLitv.. [9] [10]

Litvinov considered U. minor 'Umbraculifera', with its "denser crown and more rounded form", a cultivar of U. densa, [6] calling it U. densa var. bubyriana. Rehder (1949) and Green (1964), ignoring reports of the wild form, considered U. densa a synonym of 'Umbraculifera'. [11] [12] The U. densa photographed by Meyer in Aksu, Chinese Turkestan on his 1911-12 expedition does not appear to be the tidy grafted cultivar 'Umbraculifera' and was said to be named 'Seda'. [13] [14] Zielińksi in Flora Iranica (1979) considered 'Umbraculifera' an U. minor cultivar. [15]
In its natural range U. densa overlaps with U. pumila. The extent of hybridization between the two is not known.
