Ulmus minor 'Ademuz'
The Field Elm cultivar ''Ulmus minor'' 'Ademuz' was cloned by root cuttings from a tree growing in the eponymous town in the environs of Valencia, Spain, by researchers at the Escuela Técnica Superior de Ingenieros de Montes, Universidad Politėcnica de Madrid in 1996. The tree is one of seven discovered to have a very high resistance to Dutch Elm Disease, on a par with, if not greater than, the hybrid cultivar 'Sapporo Autumn Gold'. In the Madrid study, the appearance of the tree was rated 4.5 / 5, making it the most attractive of the seven selected cultivars. 〔Martin, J. et al. (2013). Seven Iberian Ulmus minor clones resistant to Dutch elm disease registered for their use as forest reproductive material. ''Journal of Biogeosciences & Forestry'', Vol. 8 pp172–180.

The other Spanish cultivars are: Dehesa de Amaniel, Dehesa de la Villa, Fuente Umbria, Majadahonda, Retiro, Toledo.
==Description==
'Ademuz' is monopodial, and is comparatively fast-growing, at 100 cm per annum, the fastest of the seven ''U. minor'' clones under assessment at Puerta de Hierro, Madrid. The branches are devoid of corky tissue. The leaves, on 5 mm petioles, are ovate, typically oblique at the base and acuminate at the apex, the average length and width 54 × 34 mm, the margins doubly serrate. Foliar density relative to 'Sapporo Autumn Gold' is described as 'medium'. 〔
