The Field ElmcultivarUlmus 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]
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.[10]
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,[11] 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.[12][13] Two of these nurseries also stocked 'Propendens'.[1][13]
