Description
Petzold and Kirchner in Arboretum Muscaviense (1864) described the leaves of their Ulmus campestris concavaefolia (Loudon), as "short and rounded, dark green above and whitish green below, more or less concave, that is, curling upwards at the edges so that the pale underside is more prominent than the darker upper"[https://archive.org/stream/arboretummuscav01kircgoog#page/n573/mode/1up Petzold and Kirchner in Arboretum Muscaviense (Gotha, 1864), p.557] – a description, as Henry noted, that exactly matches 'Webbiana'. 'Webbiana', as described by Henry (1913), is "pyramidal in habit, with ascending branches and sparse foliage. The leaves are folded longitudinally, so that most of the upper surface is concealed", but are "in other respects similar to those of var. stricta". Späth's 1903 catalogue said it had "small roundish leaves". The Ellwanger and Barry Nursery of Rochester, New York, described it as "a handsome variety, with small curled leaves".[https://archive.org/details/ellwangerbarrymo1898moun/page/62 Ellwanger & Barry (Mount Hope nurseries), Rochester, N.Y., 1898, p.62] Bean (1936) described it as "columnar in habit".Bean, W. J. (1936) Trees and shrubs hardy in Great Britain, 7th edition, Murray, London, vol. 2, p.618 The Royal Victoria Park, Bath, where there was a specimen, described 'Webbiana' in 1905 as "an elegant tree". The reddish seed is on the notch of the samara.[http://arboretum.harvard.edu/plants/image-search/?keyword=Ulmus&submit=Search 'Webbiana' samarae, by William Friedman, arboretum.harvard.edu/plants/image]
Etymology
The origin of the epithet is obscure, but may commemorate Philip Barker Webb, an English botanist of the early 19th century.
Pests and diseases
The tree is not known to have any significant resistance to Dutch elm disease.
Cultivation
Two 'Webbiana' were planted at Kew Gardens in 1871. One tree was planted in 1899 as U. campestris webbiana at the Dominion Arboretum, Ottawa, Canada.{{Cite book|last1=Saunders|first1=William|last2=Macoun|first2=William Tyrrell|url=https://archive.org/stream/bulletinissues00ottogoog#page/n80/mode/2up/|title=Catalogue of the trees and shrubs in the arboretum and botanic gardens at the central experimental farm|year=1899|edition=2|pages=74–75|publisher=Ottawa }} 'Webbiana' and an Ulmus campestris concavaefolia were listed separately at the Royal Victoria Park, Bath (1905).{{cite journal |last=Inman |first=T.

At least two specimens are known to survive, one in the United States and one in the UK, the latter treated as a hedging plant to avoid the attentions of the Scolytus beetles that act as vectors of Dutch elm disease.
