OriginEngland

The

Loddiges of Hackney, London, in their catalogue of 1823 as Ulmus campestris cucullata, and later by Loudon in Arboretum et Fruticetum Britannicum (1838), as U. campestris var. cucullata.[1][2]

Hooded-leaved field elm is not to be confused with U. campestris L. cucullata (= Ulmus montana cucullata Hort), the curled-leaved

wych elm cultivar 'Concavaefolia'
.

Description

Loudon described Ulmus campestris var. cucullata as having "leaves curiously curved, something like a hood". He thought the tree resembled an undescribed cultivar he called var. concavaefolia.[2][3] This brief description was dismissed by Elwes and Henry (1913) as "insufficient" for distinguishing concave- and hooded-leaved elms. They ignored Loudon's var. cucullata and expressed the view that his var. concavaefolia was identical to the cultivar 'Webbiana'.[4]

Cultivation

If Loudon's Ulmus campestris var. cucullata was the tree later cultivated as

wych cultivar 'Concavaefolia'
, which fits his description of curled grey leaves.

Field elms with 'hooded' convex leaves, however, are not unknown in cultivation, one clone being present in Brighton and Edinburgh (see below). They are not known to have been introduced to Australasia.

Hooded-leaved field elms in the UK

A pruned field elm clone with rather elongated convex ('hooded') leaves, stands in Victoria Park, Portslade, East Sussex.

The same clone is present (2019, girth 2.2 m) in Duncan Place, Leith Links, Edinburgh.[note 1][note 2][note 3] A herbarium specimen in the Royal Botanic Garden Edinburgh incorrectly labels this clone U. racemosa.[10][11] Both an U. racemosa and an U. campestris cucullata were sent by Späth to RBGE in 1902.[7] They are listed separately in Späth's 1903 catalogue,[12] where the former appears as U. racemosa Thomas, a synonym of the American species U. thomasii. The Edinburgh U. racemosa herbarium specimen appears, therefore, to have been mis-labelled. Its likely source-tree was the cucullate field elm clone labelled U racemosa that stood in RBGE in the 20th century, renamed by Melville in 1958 U. carpinifolia × U. plotii [:U. minor × U. minor 'Plotii'].[13] See also Ulmus minor 'Concavaefolia.

Varieties

A variegated form, U. minor 'Cucullata Variegata', was also in cultivation from the late 19th century.[3]
