Туркестанское генерал-губернаторство
Regel's "Gartenflora" (1881) contains an illustration, mentioned by Elwes and Henry in their account of 'Umbraculifera', of a great old tree near Eriwan. An avenue of dense globose trees, considered 'Umbraculifera' by Meyer at a time when the hybrid 'Androssowii' determination was unknown, once grew at the Russian imperial estate of Murgrab at Bairam-ali near Merv, formerly Russian Turkestan.
