Ulmus × viminalis Lodd. is an elm hybrid derived from the crossing U. minor subsp. minor × U. minor var. plotii Druce. It is a very graceful but slow-growing tree that can ultimately reach 20 metres high, with ascending branches and pendulous branchlets bearing sparse foliage. It has deeply serrated leaves < 50 mm long which are nearly symmetrical at the base, are long-acuminate at the tip, and have prominent white axil tufts on the undersides. The tree has been likened to Zelkova x verschaffeltii.
The variety was first described from specimens growing in an avenue and in coppice growth nearby at Hanwell in England in 1677, possibly arising from a natural hybrid that occurred from Essex to Oxfordshire.
