Short description: Elm cultivar


Ulmus × hollandica 'Etrusca'
Hybrid parentageU. glabra × U. minor
Cultivar'Etrusca'
OriginEngland

The hybrid cultivar Ulmus × hollandica 'Etrusca' was first mentioned by Nicholson in Kew Hand-List Trees & Shrubs 2: 139. 1896, as U. montana (: glabra) var. etrusca, but without description. The tree at Kew,[1] judged by Henry to be "not distinct enough to deserve a special name",[2] was later identified as of hybrid origin, U. glabra × U. minor 'Plotii', by Melville.

Description

The Kew specimen was a small tree with ascending branches.[2] Herbarium specimens show oval or near orbicular leaves (the latter with an abrupt, longish tip, without tapering), and a short petiole.[1]

Etymology

The tree was possibly named for its resemblance to Tuscan cypress. Melville photographed a mature, roughly conical elm at Bulby, Lincolnshire, labelling the photograph U. glabra × U. plotii [:U.minor 'Plotii'], but the tree is otherwise unconnected with 'Etrusca'.[3]

Cultivation

It is not known whether 'Etrusca' remains in cultivation.[4]

Synonymy

  • Ulmus montana (: glabra) var. etrusca: Nicholson in Kew Hand-List Trees & Shrubs 2: 139. 1896.
