This collection is the only authentic material of this species from the flora region, and indeed from the entire Himalaya. The closest other collections of the species are from the Tien Shan region and western Iran, each nearly 1000 km distant. It is difficult to imagine, however, that it is introduced at this remote locality; Distribution: Europe except extreme north, to Caucasus and Central Asia; North Africa, South Africa; adventive in Australasia and South America.
