Ulmus 'Tiliaefolia'

Ulmus 'Tiliaefolia'
GenusUlmus
Cultivar'Tiliaefolia'
OriginEurope

The Elm cultivar Ulmus 'Tiliaefolia' was first mentioned by Host in Flora Austriaca (1827),[1] as Ulmus tiliaefolia [:linden-leaved]. The Späth nursery of Berlin distributed a 'Tiliaefolia' from the late 19th century to the 1930s as neither an U. montana hybrid nor a field elm (U. campestris) cultivar, but simply as Ulmus tiliaefolia, suggesting uncertainty about its status.[2][3] Herbarium specimens appear to show two clones, one smaller-leaved and classified as a field elm cultivar,[4] the other larger-leaved.[5]

Description

[edit]

The tree was said to have ovate leaves, rounded or subcordate and not usually strongly oblique at the base.[6] Host said the leaf was biserrate. The catalogue of the Späth nursery, Berlin, describes 'Tiliifolia' [:'Tiliaefolia'] as having smooth shiny dark green leaves.[2][3]

Pests and diseases

[edit]

'Tiliaefolia' is not known to have any resistance to Dutch elm disease.

Cultivation

[edit]

No examples of 'Tiliaefolia' are known to survive. Reichenbach noted briefly that the tree was once grown in Bohemia and Austria.[7] One tree was planted in 1898, as U. tiliifolia, at the Dominion Arboretum, Ottawa, Canada.[8] Three specimens were supplied by the Späth nursery to the Royal Botanic Garden Edinburgh in 1902[9] as U. tiliaefolia, and may still exist in Edinburgh as it was the practice of the Garden to distribute trees about the city (viz. the Wentworth Elm);[10] the current list of Living Accessions held in the Garden per se does not list the plant.[11] A specimen obtained from Späth before 1914, and planted in 1916, stood in the Ryston Hall arboretum, Norfolk,[12] in the early 20th century.[13]

Putative specimens

[edit]

A tree with leaves matching herbarium specimens of 'Tiliaefolia'[14][15] stood in Dyke Road, Brighton, till 2012.

An old elm with leaves close to herbarium specimens of Späth's 'Tiliaefolia', stands (2016) in Belgrave Cescent Gardens, Edinburgh.
