| name = Ulmus minor 'Cucullata' | species = Ulmus minor | cultivar = 'Cucullata' | origin = England }} The Field Elm cultivar Ulmus minor 'Cucullata', the Hooded elm, was listed by Loddiges (Hackney, London) in the catalogue of 1823 as Ulmus campestris cucullata, and later by Loudon in Arboretum et Fruticetum Britannicum (1838), as U. campestris var. cucullata.[1][2] DescriptionLoudon described the tree as having "leaves curiously curved, something like a hood". He thought the tree resembled U. minor 'Concavaefolia'.[3] Pests and diseasesThe tree has no resistance to Dutch elm disease. Cultivation'Cucullata' is rare in cultivation. One tree was planted as U. campestris cucullata in 1897 at the Dominion Arboretum, Ottawa, Canada.[4] Three specimens of U. campestris cucullata were supplied by the Späth nursery to the Royal Botanic Garden Edinburgh in 1902. Specimens may survive in Edinburgh, as it was the practice of the Garden to distribute trees about the city (viz. the Wentworth Elm);[5] the current list of Living Accessions held in the Garden per se does not list the plant.[6] A specimen of U. campestris cucullata, planted in 1916, stood in the Ryston Hall arboretum, Norfolk,[7] in the early 20th century.[8] The cultivar is not known to have been introduced to Australasia. Putative specimens in the UKA cultivar matching the description of 'Cucullata' stands in Victoria Park, Portslade (see gallery below). The same clone survives (2016, girth 2.2 m) in Duncan Place, Edinburgh (see gallery).[9][10][11] A herbarium leaf-spray specimen from the Royal Botanic Garden Edinburgh shows the Portslade and Edinburgh clone, but labels it U. racemosa.[12] Since U. racemosa and U. campestris 'Cucullata' are listed separately in the Späth 1902 consignment to the Royal Botanic Garden Edinburgh,[5] as they are in Späth's 1903 catalogue,[13] where the former is listed as U. racemosa Thomas, a synonym of U. thomasii, the herbarium specimen or the tree it was taken from appears to have been mis-labelled. A concave-leaved tree labelled U racemosa in RBGE was determined by Melville in 1958 as U. carpinifolia × U. plotii [:U. minor × U. minor 'Plotii'].[14] If, as the evidence suggests, this was one of the three 'Cucullata', only two will have been planted in the city outside the Garden. VarietiesA variegated form, U. minor 'Cucullata Variegata', was also in cultivation from the late 19th century.[3] Synonymy
