[1] 'Myrtifolia' was listed by Nicholson in Kew Hand-List Trees & Shrubs (1896), but without description.
[4] '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.
[8] There were specimens at Arnold Arboretum in the mid-20th century, sourced in the 1920s from a tree in Cleveland, Ohio.
A small, slow-growing, dense-crowned old elm (15 m, girth 2 m), with very small narrow myrtle-like 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).
[9] Ulmus campestris myrtifolia appeared in the lists of the adjacent Wardie Nursery (Lawson Nursery group) in the late 19th century,[3] and Ulmus myrtifolia in the Lawson's of Edinburgh lists from the 1830s.
