Summary
Ulmus 'Karagatch' is a hybrid cultivar from Turkestan (from a region now part of Turkmenistan), selected in the early 20th century and considered either a backcrossing of U. × androssowii and U. pumila, or simply a cultivar of × androssowii. It was grown from seeds, introduced from Bairam Ali in Russian Turkestan by Arthur P. Davis in the 1930s, as U. 'Karagatch', under which name it was planted at Kew.[1][2]

Description edit
The Kew specimen had the appearance of a northern European field elm, more tall than broad.[1] 'Karagatch' was described by the US Department of Agriculture (1917) as a "rapid-growing elm", suitable for semi-arid regions, with harder wood than that of American Elm.[2]

Cultivation edit
'Karagatch' was present at Kew and in The Hague from the early 1930s.[3] The Kew specimen was felled in 2015 as 'unsafe'. It was cloned and remains in cultivation (see 'Accessions').
Etymology edit
The name 'karagatch' (:'black tree' in the Turkic languages, widely used for 'elm') has historically also been applied to U. minor 'Umbraculifera' (syn. U. densa) from the same region [1], and more loosely to field elm found in Turkey and to U. pumila found in Mongolia.[4]
