| cultivar = 'Myrtifolia' | genus = Ulmus | origin = England? }} The elm cultivar Ulmus 'Myrtifolia', the Myrtle-leaved Elm, was identified by Nicholson in Kew Hand-List Trees & Shrubs 2: 135, 1896 but without description. It was later listed as a cultivar by Rehder in 1939,[1] and by Krüssmann in Handbuch der Laubgehölze 2: 540, 1962. The specimen under this name in the Herb. Nicholson at Kew was considered by Melville to be a probable U. minor × Ulmus minor 'Plotii' hybrid.[2] It is not known whether the earlier cultivar 'Myrtifolia Purpurea' was related to 'Myrtifolia'. Description'Myrtifolia' was described as having leaves ovate or rhombic-ovate to oblong-ovate, 2–5 cm long with nearly simple teeth, loosely pilose on both sides. CultivationA 'Mytifolia' was present in North Road, Bath in 1902.[3] The tree is not known to remain in cultivation. Putative specimenA small, slow-growing, dense-crowned old elm (15 m, girth 2 m), possibly 'Myrtifolia',{{cn|date=September 2016}} with very small narrow leaves, stands near 90 Lower Granton Rd, Edinburgh (2016), in a garden that was once part of the elm-planted grounds of Wardie House (demolished 1955).[4] Its leaves, which flush and fall late,[5] are lance-shaped or oval (2–4.5 cm by 1.3–2 cm; petioles 0.5–1 cm). The tree, which has smooth branchlets, has been grafted on to a suberose U. minor stock. Synonymy
