[7][8] 'Turkestanica' was distributed in Europe as U. turkestanica Regel by the Späth nursery of Berlin from c.1890,[9][10][11] in whose catalogues it was listed separately from U. pinnato-ramosa, now U. pumila 'Pinnato-ramosa', and from U. campestris umbraculifera.
One tree was planted as U. turkestanica Regel, 'Turkestan Elm', in 1899 at the Dominion Arboretum, Ottawa, Canada, where it was distinguished from U.
[16] A specimen of 'Turkestanica' Regel stood in the Arboretum national des Barres, Nogent-sur-Vernisson, France, in the 20th century, where it was distinguished from 'Pinnato-ramosa'.
It was listed there under the queried synonym of Ulmus campestris turkestanica, suggesting that the Arboretum thought it possibly a field elm cultivar.
[26]) A 'Turkestanica' (listed separately from 'Umbraculifera'), "a compact grower with smallish leaves", appeared in early 20th-century catalogues of the Gembrook or Nobelius Nursery near Melbourne, Australia.
[30] A 1929 Dutch herbarium specimen renames Regel's clone "Unknown Ulmus, formerly known as U. turkestanica", reflecting this change in nomenclature.
in the 1930s, but gave as a synonym U. pumila arborea Litv., another name for 'Pinnato-ramosa', confirming that their tree was not Regel's field elm clone.
