Ulmus minor 'Microphylla Pendula'

The Field Elm cultivar Ulmus minor 'Microphylla Pendula', the Weeping small-leaved elm,[1] was first listed by the Travemünde nursery, Lübeck, and described by Kirchner[2] in Petzold[3] & Kirchner's Arboretum Muscaviense (1864), as Ulmus microphylla pendula Hort..[4][5] By the 1870s it was being marketed in nurseries in Europe and America as Ulmus campestris var. microphylla pendula.[1]

Not to be confused with Schneider's suberose cultivar 'Propendens'. Kew's U. campestris var. microphylla pendula (1896 Hand List) was equated with 'Propendens' by Henry (1913), who called it "a form of Ulmus nitens var. suberosa",[6] and by Rehder (1949),[7] and was classed by Melville as a nothomorph of 'Sarniensis'.[8][9]

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

One specimen survives at the RBG Wakehurst Place, England, 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.

In the US, an Ulmus microphylla pendula, 'Weeping Small-leaved Elm', was marketed by the Mount Hope Nursery (also known as Ellwanger and Barry) of Rochester, New York,[1] and by Frederick W. Kelsey of New York,[10] while an U. campestris microphylla pendula was supplied by the Bobbink and Atkins nursery, Rutherford, New Jersey, and the Perry Nursery Co. of Rochester, N.Y.[11][12] Two of these nurseries also stocked 'Propendens'.[1][12]
