Ulmus 'Myrtifolia'

The elm cultivar Ulmus 'Myrtifolia', the Myrtle-leaved Elm, first appeared in nursery and horticultural lists from the 1830s, as Ulmus myrtifolia and Ulmus campestris myrtifolia,[1][2][3] the name Ulmus myrtifolia Volxem being used at Kew Gardens from 1880.[4] Lawson's nursery of Edinburgh appears to have been the earliest to list the tree.[1] 'Myrtifolia' was listed by Nicholson in Kew Hand-List Trees & Shrubs (1896), but without description.[5] It was later listed as a cultivar and described by Rehder in 1939[4] and by Krüssmann in 1962.[6]

GenusUlmus
Cultivar'Myrtifolia'
OriginEngland?

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.[7]

The cultivar 'Myrtifolia Purpurea', which has larger leaves, is not related to 'Myrtifolia'.[4]

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. The petiole is 2 to 4 mm long, the samarae 12 to 15 mm long.

Cultivation

A 'Mytifolia' was present in North Road, Bath in 1902.[8] There were specimens at Arnold Arboretum in the mid-20th century, sourced in the 1920s from a tree in Cleveland, Ohio.[4]

The tree is not known to remain in cultivation.

Putative specimen

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.[10] Its leaves, which flush and fall late,[11] 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.

gollark: GTech™, of course, perfectly simulates the oracle in order to predict what *it* will do, then does the optimal thing for that.
gollark: There are two boxes in front of you, A and B. B has 10,000 dollars in it, and A contains either 1,000,000 or 0 dollars.You may choose to take either only box A, or take both boxes.A perfect oracle has predicted your choice beforehand, and filled box A with the money if and only if it was predicted that you would take only box A.
gollark: (My model for this is that if I find myself choosing between the boxes, I may be being simulated, so I can "change the past" ish)
gollark: You can't change the past, and given the boxes in front of you the two box option is strictly better.
gollark: I'll go harvest my original writeup of the money version.
