''Ulmus minor'' 'Microphylla Pendula'

Ulmus minor 'Microphylla Pendula'
Species Ulmus minor
Cultivar 'Microphylla Pendula'
Origin Europe

The Field Elm cultivar Ulmus minor 'Microphylla Pendula' was first listed by the Travemünde nursery and described by Kirchner[1] in Petzold[2] & Kirchner's Arboretum Muscaviense (1864),[3] as Ulmus microphylla pendula Hort..[4]

Not to be confused with Rehder's U. campestris var. microphylla pendula (an 1896 Kew Hand List name, given by Rehder as a synonym of Schneider's 'Propendens',[5] a similar but suberose cultivar). Henry (1913) described a microphylla pendula at Kew as "a form of Ulmus nitens var. suberosa", equating it with Schneider's 'Propendens'.[6]

A tree growing under that name at Kew was classed as a nothomorph of U. minor 'Sarniensis' by Melville.[7]

Description

Kirchner described 'Microphylla Pendula' as an elm of graceful habit with nettle-like foliage similar to but distinct from U. antarctica, the leaves being smaller and a lighter green, with pale smooth twigs and long pendulous branchlets.

Pests and diseases

Most field elm clones are susceptible to Dutch elm disease.

Cultivation

Only one specimen is known to survive, at the RBG Wakehurst Place, where it is cultivated as a hedging plant to keep it free from the attentions of the Scolytus beetles which act as vectors of Dutch elm disease. An Ulmus microphylla pendula, 'Weeping Small-leaved Elm', appeared in the 1904 catalogue of Frederick W. Kelsey, New York,[8] and an U. campestris microphylla pendula in the 1909 catalogue of the Bobbink and Atkins nursery, Rutherford, New Jersey, where it was distinguished from U. suberosa pendula.[9]

Synonymy
