Ulmus × androssowii

The hybrid cultivar Ulmus 'Androssowii' R. Kam. (or 'Androsowii'), an elm of southern Kazakhstan, Uzbekistan and Tajikistan sometimes referred to in old travel books as 'Turkestan Elm' or as 'karagach' [:black tree, = elm], its local name, is probably an artificial hybrid. According to Lozina-Lozinskaia the tree is unknown in the wild in Uzbekistan, and apparently arose from a crossing of U. densa var. bubyriana Litv. (now Ulmus minor 'Umbraculifera'), which it resembles (see the disputed species Ulmus densa), and the Siberian Elm Ulmus pumila. It is sometimes listed as Ulmus × androssowii (see below). Not to be confused with the Ulmus 'Turkestanica' distributed by the Späth nursery of Berlin. For so-called Ulmus androssowii var. subhirsuta C. K. Schneid. and Ulmus androssowii var. virgata (Planch.) Grudz. , see Ulmus chumlia....read more on Wikipedia.
